    1. Mechanical Polishing: a polishing method that obtains a smooth surface by cutting and plastic deformation of the material surface to remove the polished convex parts, such as whetstone strips, wool wheels, sandpaper, etc., mainly by manual operation. If the surface quality is high, the super-precision polishing method can be used. Super-finishing polishing is a special-purpose grinding tool, which is pressed against the processed surface of aluminum alloy die-casting parts in the polishing liquid containing abrasives for high-speed rotational movement.


    2. Chemical Polishing: the aluminum alloy die-casting parts are preferentially dissolved in the microscopic convex surface of the chemical medium than the concave part, so as to obtain a smooth surface. The main advantage of this method is that it does not require complicated equipment, can polish aluminum alloy die castings with complex shapes, and can polish many aluminum alloys die castings at the same time, with high efficiency. The core problem of chemical polishing is the preparation of the polishing solution. The surface roughness obtained by chemical polishing is generally several 10 μm.



    3. Electrolytic Polishing: the basic principle is the same as that of chemical polishing. The surface is smoothed by the selective dissolution of tiny protrusions on the surface of the material. Compared with chemical polishing, the effect of cathode reaction can be eliminated, and the effect is better.



    4. Ultrasonic Polishing: put the aluminum alloy die-casting parts into the abrasive suspension and put them together in the ultrasonic field. By virtue of the oscillating action of the ultrasonic wave, the abrasives are ground and polished on the surface of the aluminum alloy die-casting parts. Ultrasonic processing has a small macro force and will not cause deformation of aluminum alloy die castings, but the tooling is difficult to manufacture and install. Ultrasonic processing can be combined with chemical or electrochemical methods. On the basis of solution corrosion and electrolysis, ultrasonic vibration is added to stir the solution, so that the dissolved products on the surface of the aluminum alloy die-casting parts are detached, and the corrosion or electrolyte near the surface is uniform. The cavitation effect of ultrasonic waves in the liquid can also inhibit the corrosion process and benefit the surface brightening.



    5. Fluid Polishing: it depends on the high-speed flowing liquid and the abrasive particles it carries to wash the surface of the aluminum alloy die-casting to achieve the purpose of polishing. Common methods are: abrasive jet processing, liquid jet processing, hydrodynamic grinding, etc. Hydrodynamic grinding is driven by hydraulic pressure so that the liquid medium carrying abrasive particles flows back and forth at high speed across the surface of the aluminum alloy die casting. The medium is mainly made of a special compound (polymer-like substance) that flows through at a lower pressure and is mixed with abrasives. The abrasive can be silicon carbide powder.

    6. Magnetic Grinding and Polishing: the use of magnetic abrasives to form abrasive brushes under the action of a magnetic field to grind aluminum alloy die castings. This method has high processing efficiency, good quality, easy control of processing conditions, and good working conditions.

    According to the latest research released by the American Foundry Association some time ago, the direct output value of the American metal foundry industry in 2020 can reach 44.3 billion U.S dollars, which will drive the overall U.S economy up to 110.52 billion U.S dollars.

    Metal casting is a highly modern industry with a long historical foundation and cutting-edge technology, and it is the backbone of the manufacturing economy. It is an industry with a total economic output of 110.52 billion U.S.dollars, and it, directly and indirectly, provides nearly 500,000 jobs for the United States. The die casting industry is at the core of economic growth, modern infrastructure, and the defense industry.

    Castings are critical to our country's infrastructure, national defense, and quality of life's said Doug KurKul, CEO of the American Foundry Association. This latest analysis clearly shows that the metal foundry industry how importance is our manufacturing economy and the job market.

    However, for the Chinese die casting industry, the United States has an increasing demand for the die casting industry, which has led to a continuous increase in China's castings exports and stimulated more companies to develop the foundry industry. Therefore, the increase in the output value of the American foundry industry not only has an impact on the American economy and the market but also brings more orders to China and more overseas markets.

    The following is the impact of the American die casting industry on the U.S. economy and work from the figure. It can that due to the increase in the output value of the American die casting industry, the U.S. metal casting industry has nearly 500,000 jobs each year, with total wages and benefits exceeding 32 billion U.S. dollars. The contribution to federal, state, and local taxes is approximately $10.59 billion. And at the 2020 online summit held on the Internet, the American Foundry Association published an economic impact analysis, during which die casting manufacturers and decision-makers discussed the chain effect of the die casting industry on the economy.

    Ø Description:

    The corrosion products generated by the aluminum alloy die castings due to the action of the medium form a layer of film, which closely covers the surface of the aluminum alloy die castings, and changed the surface state of the aluminum alloy die castings, the electrode potential of the aluminum alloy die-casting part is greatly changed in the positive direction, and becomes a passive state of corrosion resistance.

     image.png


    Ø Advantage:

    1. After the passivation treatment, it has the characteristics of not increasing the thickness of the parts and changing the colour, which improves the precision and added value of the product and makes the operation more convenient;

    2. Since the passivation process is carried out in a non-reactive state. The passivation agent can be added and used repeatedly, so life is the cost is more economical.

    3. Passivation promotes the oxygen molecular structure passivation film formed on the surface of aluminum alloy die castings, the film layer is dense, the performance is stable, and it has a self-repairing effect in the air at the same time. Therefore, compared with the traditional anti-rust oil method, passivation The passivation film formed by chemical treatment is more stable and corrosion-resistant.


    Ø Process:

    1. The first process: pre-degreasing - main decreasing - water rinsing - water rinsing - whitening and descaling - ultrasonic cleaning -water rinsing - activation - water rinsing - water rinsing - passivation - water rinsing - water rinsing - drying. That is a relatively complete process, which is widely suitable for different passivation environments and aluminum alloy products.

    2. The second process: degreasing-water rinsing - water rinsing - activation - water rinsing - water rinsing - passivation - water rinsing - water rinsing - drying. That is the process flow after aluminum alloy polishing.

    3.  The third process: degreasing-water rinsing - water rinsing - passivation - water rinsing - water rinsing - drying. If the casting part is mechanically polished, the film colour is required to be natural, and the corrosion resistance is not high. For example, the neutral salt spray test requires about 48-72 hours, can try this simplified process.

    4. The fourth process: degreasing-water rinsing - passivation - water rinsing - drying. If the casting parts drain well and the part structure is relatively simple, then you can choose to streamline the process flow.

    1. Description

    In the die casting process, the factors of pressure and insufficient clamping force, etc. It is inevitable that die casting parts will have burrs. Recently, with the increasing quality requirements of die castings, the requirements for burrs have become more strict, and methods for deburring have emerged endlessly.

    surface_finishing5.jpg

    2. Method

    1) Manual Deburring  

    This is the most traditional and commonly used method in die casting plants, using files (files include manual files and pneumatic files), sandpaper, belt machines, grinding heads, etc. as auxiliary tools.

    Application: Low technical experience for workers, suitable for aluminum alloy die castings with small burrs and simple product structure.

     

    2) Grinding and Deburring (Vibration Grinding)

    This type of deburring includes vibration, sandblasting, rollers, etc., which are currently used in many die casting plants.

    Application: suitable for small aluminum alloy die castings with larger quantities in mass production.

    image.png

    3) Trimming  

    Use a production die to cooperate with a punch for deburring.

    Application: Suitable for aluminum alloy die castings with simple parting surfaces, and the efficiency and deburring effect are better than manual.

     

    4) Automatic Deburring

    The principle is similar to manual deburring, except that the power is turned into a robot. With the support of programming technology and force control technology, flexible grinding (pressure and speed conversion) is realized, and the advantages of robot deburring are prominent. 

    微信图片编辑_20201014161948.jpg

    Most of our die-casting parts use automatic deburring, which not only saves labour costs but also improves production efficiency.

    1. Friction Stir Welding (Friction Stir Welding, FSW for short)--Using a special form of stirring head to move forward while rotating, the friction between the stirring head and the casting parts generates heat, and the heat of friction makes the metal in the part in a thermoplastic state, and under the pressure of the stirring head, the parts to be welded together to one part.

    image.png

    2. Advantages of friction stir welding:

    • Good Welding Quality: The weld is extruded in a thermoplastic state, and belongs to solid-phase welding, which has excellent mechanical properties.

    • Widely used: Not limited by shaft parts, it can be welded straight welds, fillet welds, girth welds, etc., expanding the scope of application

    • No need for high operating skills and training: Friction stir welding uses automated mechanical equipment for welding, avoiding the dependence on the technical proficiency of operators, stable quality, and high repeatability.

    •  No need for welding wire and a protective atmosphere: There is no need for filling materials and shielding gas during welding, no pre-treatment of the surface of the casting parts before welding, no protective measures need to be applied during the welding process, which simplifies the welding process.

    • High dimension precision: Since friction stir welding is solid-phase welding, its heating process has the characteristics of high energy density and fast heat input.

    • Green welding method: The friction stir welding process does not produce arc radiation, smoke and spatter, and has low noise, which realizes the environmental protection of the welding process. Therefore, friction stir welding is called the "green welding method".

    • The "fuel tank" of new energy vehicles-batteries: the battery is one of the main parts of electric vehicles, and the function of the battery is the only source of power for the vehicle's drive system. At low speed and starting, the battery plays the role of the main power source of the car's drive system; when accelerating at full load, it acts as an auxiliary power source; during normal driving, deceleration, and braking, it acts as storage energy.

    图片1.png

    • The key to determining power-motor: The motor has two working states, one is used as a motor, responsible for converting the electrical energy in the battery system into kinetic energy, and when it is not needed to drive the vehicle, it can also play the role of a generator Features, convert the kinetic energy of the vehicle into electric energy and store it back in the battery. The power supply provides electric energy for the driving motor of the electric vehicle. The electric vehicle motor converts the electric energy of the power supply into mechanical energy and drives the wheels and working devices through the transmission device or directly.

    • The "housekeeper" of the new energy vehicles-electronic control system: The electronic control system of electric vehicles is the brain of electric vehicles, which refers to the entire vehicle control system, which integrates the functions of ECU and TCU (engine and gearbox control computer). We all know that the ECU control of traditional fuel vehicles is more complicated. The fuel injection quantity, timing phase, throttle opening of the engine, ignition, exhaust gas circulation, etc. all need to be controlled, and according to the driver’s intentions, the ECU must also interact with the gearbox. The program is calibrated in coordination to complete smooth gear changes and fully understand the driver's intentions.

    • Reasons:

    ① It is caused by the side and corner of the mold, equipment, or worktable when opening the mold.

    ② The castings of each operation process are stacked.

    ③ Improper behaviour of each process, such as throwing.

    ④ During operation and transfer between processes, the castings were not separated and protected, or the castings collapsed.

    ⑤ During each operation procedure, such as die-casting pick hooks, picking pliers, files and punches in the cleaning process.


    • 5 ways of avoiding “scratches”:

    ① When the casting is demoulded, be careful not to bump.

    ② Obey the operating instructions, the castings are not allowed to be stacked and must be neatly placed in the workstation equipment one by one.

    ③ Not allowed throwing the castings during production, and must be handled carefully.

    ④ Placed the castings must be protected separately, and the transfer must be slow to prevent them from collapsing or falling.

    ⑤ Using the tools correctly. It is not allowed to hook or pinch the casting body when removing them from the moulds.

    EMP treats every customer's project with a careful, scientific, and rigorous attitude, and we never allow the slightest flaw in the die-casting parts.

    A. Reason:

    1. Sticking mold.

    2. The iron content in the aluminum alloy is less than 0.6%.

    3. The ejection of the casting is skewed, or the core axis is skewed.

    4. The core and wall have pressure scars.

    5. The wall surface is rough.

    6. The casting slope of the core and wall is too small or the inverted slope appears.

    7. Paint is often not sprayed.

    B. Measures:

    1. Correct the mold to ensure the manufacturing slope.

    2. Polish the indentation.

    3. the rational design of the gating system, avoiding the metal core flow hedges, wall type, and appropriate to reduce the filling speed.

    4. Modify the mold structure.

    5. Polish the surface.

    6. The amount of paint is thin and even, and paint cannot be missed.

    7. Appropriately increase the iron content to 0.6~0.8%. Aluminum alloy die-casting parts can be manufactured into die-cast auto parts, die-cast auto engine pipe fittings, die-cast air-conditioning parts, die-cast gasoline engine cylinder heads, die-cast valve rocker arms, and die-cast valve branches.

    1. There is gas in the raw material. In the production of die castings, since the main component of the gas contained in the aluminum liquid is hydrogen, the level of hydrogen content in the aluminum alloy liquid is directly related to the number of pores produced in the casting. The holes in the casting reduce the mechanical properties, corrosion resistance & airtightness of the alloy.


    2. The influence of mold gating system. The gating system determines the design quality of a die-casting mold, and it is the main factor that determines the quality of the die-casting parts in later production. The runner is open in the direction of the dense side, the molten aluminum will reach the blind spot first, and when it returns, it will produce a vortex and roll-up. The quality of the left side of the casting is reduced & the airtightness is reduced.


    3. Equipment performance. Air holes, shrinkage holes, and cold zones in aluminum die castings are also the air leakage of causes in aluminum die castings, and the performance of the equipment plays an important role. For products with strict requirements on airtightness, a suitable die-casting model needs to be selected.


    4. Method of operation. During the die casting process, some coatings have high volatilization points & large air volume directly affects the casting porosity. The release agent is sprayed manually, and the dosage has determined by experience. If the spray volume is too large or the spraying time is too long, a large amount of gas will evaporate. Also, low mould temperature & untimely volatilization will result in large porosity.


    5. Control the machining allowance. During the moulding process of die castings, the cavity has filled at the fastest speed, molten aluminium can be rapidly solidified in the mould to form a product, and holes or shrinkage will appear inside the casting. Due to the rapid solidification, the surface layer of the casting is a fine particle layer. The mechanical properties of these fine particles are very high. The production process changes for different castings, the thickness of the dense structure layer will be different.


    6. Reasonably add rebates. The pinhole degree reflects the spatial distribution density of pinholes and is a factor that affects the casting airtightness. Due to the influence of small holes and oxidized inclusions in recycled materials, there are more pinholes in the castings, resulting in a higher scrap rate of single castings in production. To save energy, waste materials and runner recycling are reused in production, resulting in a decrease in the casting airtightness.


    7.  Choose a reasonable pressure chamber fullness. After selecting the punch diameter and die casting machine, each casting has a different molten metal weight. If the amount of molten metal injected into the pressure chamber is insufficient (when the pressure chamber is low), the pressure chamber gas cannot remove, and turbulence will form, which is easy to participate inside. Defects such as pores and insufficient perfusion will appear at this time. Too much oxide scale in the pressure chamber will form a partition wall inside the casting, and the casting strength will reduce. Under the action of the leak test pressure, leakage is prone to occur.

    According to analysis, it is difficult to solve the problem of poor air-tightness of die castings. The reason may be the comprehensive influence of various casting defects.  When dealing with poor airtightness, it is necessary to analyze the alloy properties, the process, and the mold. Then find out the main reason and take targeted measures, which can effectively improve the air-tightness of aluminum alloy die castings.

    1. Zinc Alloy

    Zinc alloy is an alloy based on zinc and other elements. Commonly added alloying elements include low-temperature zinc alloys such as aluminum, copper, magnesium, cadmium, lead, and titanium. Zinc alloy has a low melting point, good fluidity, and is easy to weld, braze and process plastics. Also, in the atmosphere, zinc alloys are highly corrosive and easy to recycle. Material made by melting method, die casting, or pressure processing.

    • Advantages of Zinc alloy:

    1.  Good casting performance. It can die-cast precision parts with complex shapes and thin walls, and the surface of the castings is smooth.

    2. Various surface treatments are available. E. g: electroplating, spraying, painting, polishing, grinding, etc.

    3. When melting and die-casting, it does not absorb iron, does not corrode the pressure, and does not stick to the mold.

    4. It has good mechanical properties and abrasion resistance at room temperature.

    5. Low melting point. Melty at 385°C, easily die-casting.


      B. Aluminum Alloy

    Aluminum alloy is the most widely used non-ferrous metal structural material in the industry and used in aviation, aerospace, automobile, machinery manufacturing, shipbuilding, and chemical industries. With the rapid development of the industrial economy, the demand for aluminum alloy welded structural parts is increasing, and the weldability of aluminum alloy also study in-depth.

    •  Advantages of Aluminum Alloy:

    1. The density is small. The density aluminum alloy is close to 2.7g, about 1/3 of that of iron or copper.

    2. Aluminum alloy has high strength. After cold working, it will increase. Heat treatment is strengthening other grades of aluminum alloy.

    3. Good electrical and thermal conductivity. The electrical and thermal conductivity of aluminum is second only to silver, copper, and gold.

    4. Good corrosion resistance. The aluminum surface is prone to naturally produce a dense and strength AL2O3 protective film, which can protect the substrate from corrosion. Through artificial anodic oxidation and coloring, cast aluminum alloy with good casting performance or deformed aluminum alloy with good processing plasticity can obtain.

    5. Easy to process. After adding certain alloying elements, a cast aluminum alloy with good casting properties or a deformed aluminum alloy with good processing plasticity can obtain.


    • The differences between zinc and aluminum alloy as below chart:

    Zinc-Aluminum-chart.png

    Everyone who sees here has already felt the difference between zinc alloy and aluminum alloy. Each has its advantages and disadvantages. Should choose the material suitable for your product according to the quality, technology, life, and other product requirements. EMP insists on producing according to customer needs and using the highest quality and most suitable materials.

    • The post-treatment of the heat sink housing surface refers to the filling, surge, and powder spraying of the internal anti-corrosion paint.

    • Common defects are as follows:

    1.  The internal anti-corrosion cannot be hung up. Because of poor pre-treatment effect or improper coating configuration, the welding area is directly exposed to water & corrosion occurs.

    2. After drying, there are honeycombs or cracks on the internal anti-corrosion end. If the inner cavity is wet and full of anti-corrosion paint, water will evaporate. The raw material of water-based paint, the ratio problem, too much water/ethanol can also cause evaporation. Solvent-based internal anti-corrosion coatings increase the boiling point. If the solvent content is lower, the time in the mold cavity is shorter, which will cause the solvent to evaporate rapidly during the baking process, and honeycomb holes will appear. Thus, after filling the paint, it requires at least 1 hour and air-dried as soon as possible.

    3. Many cases of heat sink housing cracks cause by local accumulation of paint that is too thick and not fully cured. The upper part solidifies, while the lower part is still evaporating the solvent, causing cracks.

     

    • Above drawbacks, impurity ions in water infiltration/accumulation/fouling. Or the accumulation of scale inhibitors (acid or alkali) added to the water will cause faster corrosion.

    • Internal anti-corrosion, no adhesion. The internal anti-corrosive resin and filler are important.  

    1. With less resin, the film becomes brittle and not smooth, which will reduce the corrosion resistance.

    2. The filler fineness is insufficient, and many uneven particles appear in the film. Large particles are easily washed away and cause pitting corrosion.

    3. The filler grade is too low, resulting in the film thickness does not increase, the hiding power reduces, the hardness is insufficient, and the corrosion resistance being reduced.

    •  The defects of the outer coating include broken wires, cracks on the exposed bottom, serious orange wires, pinholes, small cracks, etc. Under normal circumstances, the material is too poor, the pre-treatment is unqualified, and the heat sink processing technology is unqualified. Due to the long development time of powder coatings, plastic powders above the medium level will not have quality problems.

    • It refers to neutral total carbon emissions, which are balanced by offsetting as much carbon as emissions.

    For example, humans produce 10g of carbon dioxide when they breathe, while plants absorb 10g of carbon dioxide during photosynthesis. In this process, the amount of carbon emitted and the amount of carbon absorbed cancel each other out, and no produced excess carbon dioxide.

    Carbon_Neutral.png

    • Impact:

    1. "Carbon neutrality" electrifies transportation. To achieve "carbon emission neutralization", policies have been explored to explore transportation electrification plans and policies have been formulated to ban the sale of fuel vehicles.

      Electrification-of-transportation.jpeg

      In the future, transportation will electrify, and fuel vehicles will gradually replace. The utilization rate and sales volume of new energy vehicles will increase. It even promotes the development of the automobile industry to hybrid and pure electric cars and expands the business of electric vehicle manufacturers.

      new-energy-vehicles.jpg

    2. The development of automobile brands electrification. Automobile companies such as Volvo, Volkswagen, and Mercedes-Benz have all proposed electrification strategies. And stop the production of pure fuel vehicles, switch to electric, and develop in the direction of hybrid and pure electric. From last year to this year, the stock prices of many electric vehicle companies have been affected and have soared. Among them, Tesla CEO Musk was promoting to the world's richest man. From this year to the next ten years, the electrification of automobiles may become the mainstream trend.

      energy-car.jpg

    3. The industrial chain that drives automobile production. When the demand for electric vehicles gradually increases, the need for manufacturers and aluminum alloys will also increase, which promotes the development of aluminum alloy die-casting plants. The formation of the industrial chain will help the economy and production development, reduce carbon emissions and protect the environment.

    1. Different sources of energy.

    As can be seen from the name, electric cars use electricity, while ordinary cars use ordinary gasoline. Due to different energy sources, their use methods are also unequal. Electric vehicles mainly rely on charging, and fuel vehicles mainly rely on petroleum.

    2. The waiting state is different.

    While the car is waiting, ordinary vehicles still need to consume gasoline. For example, when you encounter a red light or a traffic jam, you are unlikely to turn because the waiting time at this time is uncertain. It may be a few minutes or tens of minutes, which is different for electric vehicles. The electric car is not afraid of stalling, it can stop completely, and it will not take long to start like an ordinary car. In addition, some electric vehicles have battery panels. When waiting for the auto, if there is sun, you can charge while waiting.

    3. The emissions are different.

    General energy vehicles burn gasoline, so the exhaust contains a lot of exhaust gas, which causes harm to air pollution. The air quality in big cities is low, mainly because cars burn too much oil and exhaust gas exceeds the natural balance. Electric vehicles have no emissions, are perfectly environmentally friendly, and will not adversely affect the environment.

    • The motor controller is the nerve centre connecting the motor and the battery, used to adjust the performance of the vehicles. It not only guarantees the basic safety and precise control of the car but also exerts sufficient power. At present, the more common forms in the industry are single motor controllers, integrated motor controllers, and integrated powertrains. Compared with micro-face logistics and special vehicles, there are more single-motor controllers. Light trucks and buses use a second all-in-one motor controller. The overall development goals are the best performance, reliability, best cost, and lightweight development.

    electric-vehicle-motor-controller-housing.png


    • The motor controller is used to drive the main motor on the electric vehicle. Generally, it receives the signal of the whole vehicle controller to control the starting, running, speed regulating, and stopping of the main motor. Together with the whole vehicle controller, it is just like the brain of the electric vehicle being an important part of the electric vehicle. At present, the motor controller is increasingly integrated, including single main drive controller, three-in-one controller (integration: EHPS controller + ACM controller + DC/AC), five-in-one controller (integration: EHPS controller + ACM controller + DC/DC + PDU + dual-source EPS controller), passenger car controller (integration: main drive + DC/DC) and other controllers.


    • Function: When the controller protects by over-discharge or the motor is running, a fault or malfunction may cause damage and other malfunctions. The circuit will take protective measures based on the feedback signal.

    A.Improve efficiency and output 

    1. The foam model used for the infiltration of aluminum alloy die castings adopts mechanical foaming. While ensuring the quality of the model, the production speed is also quite fast.

    2. The dipping process of aluminum alloy dies castings simplifies the cumbersome steps of traditional crafts, such as forming the core, which is time-consuming, labour-intensive, and inefficient.

    3. The aluminum alloy dies casting is immersed in a box for multiple injections until the metal solution uses up.


    B.Cost savings

    1. The infiltration mold used for aluminium alloy dies castings can be used for life with almost no loss, reducing or eliminating mold costs.

    2. The impregnation of aluminum alloy dies castings abandons the traditional core forming process, saves labour, and reduces manufacturing costs.

    3. The penetration of aluminum alloy dies castings has gradually increased the number of female workers in the foundry industry. All aspects of labour and wage costs have been reduced.

    4. The sand used for the soaking of aluminium alloy die castings can be recycled, and the loss rate is 2%-5%.

    5. Immerse the die-casting parts in the impregnation liquid, penetrate the loose parts inside the die-casting parts, and improve the air-tightness of the die-casting parts.

    1. Production process

    Incoming material selection, smelting and refining → die-casting molding → shaping and trimming → finishing → cleaning and cleaning → assembly and assembly



    2. Process value

    According to the structural modeling characteristics and processing conditions of the shell aluminum alloy castings, the casting pressure needs 350T. In addition, when the staff summarizes the experience of similar parts processing in the past, they will find that once the mold and process values are inappropriate. When the aluminum alloy parts are open, the liquid metal filling time will be too short. The timely volatilization of a large amount of gas in the closed cavity is blocked and blocked, resulting in a series of quality defects such as large dense pores and oxidized impurities in the finished product, which reduces the qualification casting rate. Therefore, precise positioning requires during use, and the processing needs controlling within 0.5mm. Improve the compression resistance of the parts, shorten the machining time, and enhance the inherent quality of the production of aluminum alloy parts for the shell.



    3. the model scheme

    In the production and processing process of aluminum alloy parts, it is necessary to conform to the wave of social development, realize information innovation, introduce corresponding information technology, improve work content, and increase work efficiency. The staff repeatedly compared and polished, and when filling with liquid sulfur, the model with a large flow channel flow will select as the actual part processing mold. It can improve the hidden defects inside the castings and increase the yield rate.

    filling.jpg


    4. Melting temperature

    According to the actual weight of the finished product, a 350T high-quality cold die-casting machine can use as the main body for die-casting of parts. Real-time temperature control is necessary. In the case of semi-finished products, they should maintain within the range of 640°C to 20°C. In the process of a liquid metal filling, to keep the pressure stable, it should be emphasized to prevent errors such as splashing and laminar turbulence, and the pressure rise rate is limited to 1.5kP/s. It helps to avoid repeated oxidation of slag inclusions and frequent scouring of the mud core by molten metal.



    5. Alloy liquid purification

    To improve product quality, refining is carried out when the semi-finished alloy is completed. At the same time, install a fibre filter at the riser nozzle and a ceramic filter at the level gate of the gold tail liquid. It is also necessary to add a filter screen made of double-layer fibres to the residue of the horizontal gate and the slit to achieve three-time fine filtration.



    6. Defect detection

    In the quality control of aluminum alloy production and processing, X-rays must be used to complete flaw detection tasks and control the internal quality of parts. When shell parts are processed in batches, visual examination and X-ray inspection will lead to labour and capital shortages. Therefore, the staff can use CAE modern technology to analyze and monitor the entire production process of the parts and find out the hidden quality problems of the components in the casting process in time. The quality problems of integral castings are limited to semi-finished blanks and completely concentrated processing stages.

    • Methods to reduce porosity in aluminum die-casting products


    1. Ensure the refining and degassing quality of aluminum alloy smelting, and select a good refining agent and degassing agent to reduce the gas content in the aluminum water. Remove the scum, bubbles, and other oxides on the liquid surface in time to prevent the gas from entering the die-casting parts again.


    2. Choose a great release agent. The selected release agent should not generate gas during the die-casting process and has good release performance.


    3. Ensure that the exhaust of the mold is unobstructed, and ensure that the gas in the mold is completely exhausted, especially the exhaust channel for the final polymerization of the aluminum liquid.


    4. Adjust the die-casting parameters, and the filling speed should not be too fast to prevent air entrainment.


    5. Pay attention to the use of core pulling and cooling in product design and mold design to minimize the shortcomings of excessive wall differences.


    6. The pores that often appear in the fixed position should be improved from the mold and design.

    1. To ensure the refining and degassing quality of aluminum alloy smelting, select good refining agents and degassing agents. It reduces the gas content in the aluminum water, removes scum, foam, and other oxides on the liquid surface in time, and prevents the gas from being brought into the die-casting again.


    2. Choose a good release agent. The selected release agent should not generate gas during the die-casting process and has good release performance.


    3. Ensure that the mold exhaust is smooth and not blocked. Smooth exhaust to ensure that the gas in the mold is completely exhausted, especially the exhaust channel where the aluminum liquid is final aggregation must be unobstructed.


    4. Adjust the die-casting parameters, and the filling speed should not be too fast to prevent air entrainment.


    5. Pay attention to the use of core-pulling cooling in product design and mold design to minimize the shortcomings of excessive wall differences.


    6. The pores that often appear in the fixed position should be improved from the mold and design.


    • The uneven wall thickness of the casting is prone to defects such as shrinkage. The solution is to increase the feed channel of the casting (increase the fillet of the casting) when the thickness changes to avoid the vertical shape in the casting.


    • Another method is to increase the temperature difference during the solidification of the casting. This not only guarantees the bottom-up solidification sequence of the casting but also reduces shrinkage.


    • The other is to reduce the amount of gas discharged from the casting cavity. If the amount of gas discharged from the cavity is too large, the casting will have many cavities.

    1. The anodizing temperature of die-cast alumina colouring is generally below 23 °C. If the temperature is too high, the consumption of cold sealant will be large, and the surface will turn green.


    2. When die-casting aluminum is anodizing and coloured, take out the falling aluminum in time. Otherwise, it will accelerate the increase of pH and fluorine consumption.



    3. It needs to be cleaned in time after anodizing because staying in the oxidation tank will affect the sealing. Otherwise, it will cause pollution and increase the fluorine consumption of the sealed tank.



    4. After the closed fluoride tank is regular with ammonium fluoride, it should fall once to clear the bottom. The hydrofluoric acid-adjusted fluorine sealed tank should be produced 5-10 minutes after addition, preferably in the form of a 10% dilute solution.


    5. To improve the sealing quality and speed up the drying speed, after cold sealing, it is recommended to wash with hot water at 55±5℃ for 10 to 15 minutes, also known as cold sealing post-treatment.

    • To achieve ultra-high data transmission rate and extremely low network delay, on the one hand, the signal transmission power consumption of 5G AUU (RRU and antenna integrated unit) increases significantly; Power consumption will also increase significantly. According to the data of the tower company, the power consumption of a 5G single station is 2.5-3.5 times that of 4G. From the perspective of thermal design, the heat generation of the base station increases, and the difficulty of temperature control increases sharply. To solve the heat dissipation problem of 5G base stations, it is necessary to develop new high-conductivity die-casting materials.

    • Al-Si casting alloys are often used as die-casting aluminum alloy materials. The main problem with this type of alloy is that the thermal conductivity is low, but it does not meet the design requirements. Taking the commonly used ADC12 alloy as an example, the thermal conductivity of aluminum is about 96W/(m·K), while the thermal conductivity of aluminum profile-6063 is 200W/(m·K). Therefore, it is a problem to be solved to study the factors affecting the thermal conductivity of die-casting aluminum alloys and try to improve its thermal conductivity.

    • Due to the purifying effect of boron on aluminum parts, three aluminum alloy materials with high thermal conductivity have been developed. It not only ensures high thermal conductivity but also improves the casting performance of the alloy. High thermal conductivity aluminum alloys have been widely used in base station radiators, photovoltaic inverter radiators, 5G optical modules, LED lights, and other fields.

    With the need for a light-weight, energy-saving, and emission reduction, aluminum alloys are more and more used in transportation fields such as aerospace, automobiles, and ships. The use of light-weight materials for automotive parts is an effective way to reduce the weight of a vehicle. Aluminum dies casting is the preferred choice due to its excellent material properties, ease of forming, and light-weight. The application of aluminum alloys die castings in automobiles mainly focuses on housing parts, engine parts, and other components.


    1 The shape of pores in aluminum alloy die castings

    Porosity is a spherical porous defect with a smooth inner surface in die castings. Generally, the gas precipitated in the form of bubbles during the cooling and solidification process is too late to discharge the liquid level and remains in the die casting to form. Can not be discharged in the casting solidification process to form a small scattered pore, the so-called pinhole, and more round and uneven, often appear in the thick section of the casting and the cooling rate is slower parts.

    2 Techniques for optimizing stomata

    2.1 Dual-channel high vacuum technology

    Through the application of the new dual-channel high vacuum technology, the gas content in the mold cavity and the pressure chamber is reduced to make it close to the vacuum state, and the application of purification and degassing technology is increased to reduce the gas content of the melt, to reduce the formation of air holes in the die casting.


    2.2 Optimization of the powder coating process

    Optimize the powder coating process, and reduce the residual amount of mold release agent by shortening the powder coating time, improving the nozzle direction, and prolonging the blowing time, which can effectively avoid the intensive pinhole defects caused by the instantaneous vaporization of molten aluminum and moisture.


    2.3 Ways to Improve Porosities for Aluminum Alloy Die Casting
    Reasonable choice of high-speed switching point has a great influence on the internal quality of die casting parts. Colleagues improved the pouring system of die casting parts according to the internal quality requirements of products, which has positive significance for the improvement of die casting part’s quality.

    As we all know, Engine is the heart of the car and it plays a grate influence on mechanical machine.Engine is an energy conversion institution,upcoming gasoline or gas heat,through the gas cylinder in seal burning,to push piston expenditure then turns the energy into mechanical energy,which is the most basic principle of engine.And the body is the framework of the engine and the installation foundation of the engine's institutions and systems. All the main parts and accessories of the engine are installed inside and outside the body and bear various loads. Therefore, the body must have enough strength and stiffness. The block is mainly composed of cylinder block, cylinder liner, cylinder head and cylinder gasket.


    For example,the cylinder head is mounted on the car cylinder block to seal the cylinder from the upper part and form a combustion chamber. It often contacts with high temperature and high pressure gas, so it bears a lot of heat load and mechanical load. There is a cooling water jacket in the cylinder head of a water-cooled engine. The cooling water holes at the lower end of the cylinder head are connected with the cooling water holes of the cylinder body. Use circulating water to cool high temperature parts such as combustion chamber.Cylinder head is usually cast with gray cast iron or alloy cast iron. But as aluminum alloy has good thermal conductivity and is conducive to improving compression ratio. Therefore, in recent years, more and more aluminum alloy cylinder head has been used.


    Regarding for the car engine parts, in order to effectively reduce the weight of the whole vehicle, 1.4L gasoline engine uses aluminum alloy cylinder block, which has achieved very obvious lightweight effect. And using aluminum material and plastic intake pipe processed by special technology instead of traditional metal intake pipe can not only achieve lightweight effect, but also effectively reduce the resistance of intake pipe wall, improve intake efficiency and increase engine power.

    1.Overview of auto starter parts

    What is auto starter?Engine starting needs external support, the car starter is playing this role. Generally speaking, the starter use three parts to realize the whole starting process. The DC motor introduces the current from the battery and causes the driving gear of the starter to produce mechanical movement. The driving mechanism meshes the driving gear into the gear ring of the flying wheel and can automatically detach after the engine starts. The opening and closing of the starter circuit is controlled by an electromagnetic switch.Among them, the motor is the main internal part of the starter.

    The starter is the core part of the starting system. The starter consists of three parts:DC series motor, transmission mechanism and control device in which there contain aluminum alloy parts of end cover, casing, and one-way clutch. Why there needs aluminum alloy part in a starter?Generally speacking, aluminum alloy is lighter and has stronger heat dissipation potential than any other material.

    EV battery box overview

    The main purpose of the battery shell of an electric vehicle is to accommodate and protect the battery. They come in different shapes and sizes, and aluminum and steel are the traditional materials for battery housings. The main obstacle to the large-scale adoption of electric vehicles is the fear that they will not be able to drive far enough on a single charge. Composite materials can provide an improved alternative to significantly improve the performance of electric vehicles. In order to alleviate this problem, it is necessary to provide qualified cars, and the parts that make up them must also have these qualities.

    Advantages of EV battery case

    Lose weight. The main driving force for choosing composite materials is that if the shell is made of 100% composite materials instead of aluminum, weight savings of up to 40% can be achieved, which will play an important role in the large-scale adoption of electric vehicles. 

    Reduce noise. Noise is the result of acoustic propagation of vibration or noise in the cabin. 

    Although not obvious in other ways, it is important in terms of commerciality and driving experience. 

    Security issues. The strength and stiffness of the composite battery shell exceeds that of aluminum or steel and can be designed as part of the body structure to protect not only the battery but also the passengers. 

    Pultrusion. Mass production is essential to reduce overall costs. 

    Continuous manufacturing methods can be used to produce battery box components for electric vehicles, and Pultrusion process can be used to produce stronger but lighter products.

      With the development of industries such as automobiles and motorcycles, and the realization of requirements for improving the quality of die castings, saving energy consumption and reducing pollution. The application range of non-ferrous metal alloy die castings, especially light alloy (aluminum and magnesium alloy) die castings is expanding rapidly. The information shows that the replacement of steel castings with aluminum alloy and magnesium alloy castings in industrially developed countries is becoming an important development trend. At present, die casting has become one of the more widely used processes in the forming process of aluminum alloys for automobiles, accounting for 49% of various automobile forming processes.


      At present, there are about 3,000 non-ferrous metal die-casting enterprises in China, and the average annual increase rate of die-casting output is 12.58%, of which aluminum alloy die-castings account for more than 3/4 of all die-castings. The market capacity of China's automotive aluminum alloy die-casting parts is about 84 billion in 2018. The market capacity in the next 2-3 years is expected to exceed 100 billion yuan and maintain a high single-digit growth rate every year.


      With the improvement of technical level and product development capabilities, the types and application fields of aluminum alloy die-casting products are continuously expanding, from automobiles to communications, medical equipment, machinery, and artificial intelligence and other industries.


      Since the die-casting aluminum alloy was put into commercial production in 1914, with the development of the automotive industry and the invention of the cold chamber die-casting machine, its alloy types have been rapidly developed. Such as the die-casting aluminum alloy Japanese standard ADC12, ADC10, American standard A380, A360, EU ENAC43400, ENAC44300, German standard ALSi9Cu3, etc., are the most commonly used aluminum alloys for the die-casting factory.


      EMP's products are mainly composed of small and medium-sized parts, which have a wide range of products and many types. With the increase of orders and the expansion of the market size, the EMP team has achieved a good annual output value of 250 million yuan in 2019. The continuous development of the market and the long-term cooperation of customers have enabled EMP to better grasp the industry trends and product development directions and strive to create new glories.

    Definition of aluminum die casting parts

    Aluminum alloy die casting is a kind of pressure casting part, which uses the die casting mechanical die casting machine to install the casting mould, and pours the heated liquid aluminum alloy into the feed port of the die casting machine. The aluminum alloy parts with limited shape and size of the die are cast by the die casting machine. Such parts are usually called aluminum alloy die castings.


    Advantages of aluminum die casting parts

    Because the metal aluminum alloy has good fluidity and plasticity.Aluminum alloy die castings can not only make a variety of complex shapes, but also have high precision and finish.The mechanical processing of castings and the casting allowance of metal aluminum alloy are reduced, which not only saves electric power and metal materials, but also greatly saves labor costs.Aluminum alloy has excellent thermal conductivity, low specific gravity and high processability.


    Applications of aluminum die casting parts

    Aluminum alloy die castings are widely used in automobile manufacturing, internal combustion engine production, motorcycle manufacturing, motor manufacturing, oil pump manufacturing, transmission machinery manufacturing, precision instruments, landscaping, power construction, architectural decoration and other industries.

    Aluminum alloy die-casting parts can be made into aluminum die-casting automobile parts, aluminum die-casting automobile engine fittings, aluminum die-casting engine cylinder, aluminum die-casting gasoline engine cylinder head, aluminum die-casting valve support, aluminum die-casting power accessories and other parts.


    Recycling aluminum die casting parts

    There is little difference in the function of primary and secondary recycled aluminum die-casting. Secondary aluminum alloy is made of pure aluminum mixed with magnesium, iron, copper and other materials. Due to cost, it is rarely used in pure aluminum casting. More than 95% of aluminum castings made in North America are made from recycled aluminum after consumption. The ease of use of aluminum alloy in die casting and its lighter weight and durability make it the first choice for designers in almost all industries, for which secondary aluminum needs only 5% of energy to be produced. Most of the energy consumption of aluminum die casting is used to heat and remelt the metal in the manufacturing process.

    1.Overview of Cylinder Head Cover

    There are three types of cylinder heads include flathead, overhead valve and overhead camshaft cylinder heads, each of which can be made of cast-iron or aluminum material, depending upon the specific system in which they are being used in. Our engine cylinder head cover is made of aluminum alloy. In general, aluminum alloy is lighter and has stronger heat dissipation potential than any other material. Meanwhile, Why choose aluminum alloy to be the material of cylinder head valve cover? Not only aluminum cylinder head cover can reduce the weight of the car, but also improve the heat dissipation effect of the engine.Cylinder head covers serve to seal off the cylinder head space from the outside of the engine. As a result of operation of the internal combustion engine, blow-by gases from the combustion process and oil droplets from the lubricant system of the engine are present inside the cylinder head.

    A cylinder head is usually located on the top of the engine block. It serves as a housing for components such as the intake and exhaust valves, springs and lifters and the combustion chamber.


    2.Advantages of Cylinder Head Cover

    It conveys air and gasoline to the combustion chamber and serves as a cover for the cylinders. The main advantage of the cylinder head is to help the head gasket seal the cylinders properly so that they are able to build enough compression for engine operation.

    Electric vehicle battery charger

    In terms of control safety technology, the three-layer safety monitoring technology of the whole vehicle control system for electric vehicles was developed, and the working parameters related to vehicle safety were monitored and processed from the functional level, the software level and the hardware level,and the large-scale operation of the electric vehicle was solved.Security monitoring issues.


    The controller aluminum shell has high specific strength, specific modulus, fracture toughness, fatigue strength and corrosion resistance. Because the aluminum alloy material has low density and is non-magnetic, the alloy phase is stable at low temperatures.


    The aluminum shell of the electric car battery parts will be treated by hot and cold processes, and the aluminum shell of the battery thus produced will have strong corrosion resistance. The controller of the aluminum housing is thus safer.


    This kind of shell also has good ductility and can be made into a light alloy with many metal elements. Its chemical properties are stable, non-magnetic, and can be recycled. It is a benign and recyclable metal material.


    The aluminum shell is also small in density and light in weight compared to other metals, so it can be said that the aluminum shell is a good partner for the new energy controller.

    (1)Shape and structure requirements of custom aluminium die casting:

    a. Eliminate the internal side concave;

    b. Avoid or reduce the core pulling part;

    c. The reasonable die-casting structure can not only simplify the die casting structure, reduce the manufacturing cost, but also improve the casting quality,


    (2)Wall thickness requirements of custom aluminium die casting design:

    The wall thickness of die casting is a special factor in the process of die casting. The wall thickness is closely related to the whole process specification, such as the calculation of filling time, the selection of internal gate speed, the calculation of solidification time, the analysis of mould temperature gradient, the effect of pressure (final specific pressure), the length of mould retention time, the height of casting ejection temperature and operation efficiency.


    (3)Requirements for design reinforcement of custom aluminium die casting:

    The function of the rib is to improve the strength and rigidity of the parts after the wall thickness is thinner, to prevent the reduction of the shrinkage deformation of the custom aluminium die casting. And avoid deformation when the workpiece is ejected from the mould. The thickness of the custom aluminium die casting bar should be less than the thickness of the wall, generally 2 / 3 ~ 3 / 4 of the thickness;


    4Fillet requirements of custom aluminium die casting design:

    On the custom aluminium die casting, the connection between the wall and the wall, no matter the root of right angle, acute angle or obtuse angle, blind hole and groove, shall be designed as the round corner. Fillet connection is not used only when it is expected to be determined as the part of the parting surface, and the rest parts must be fillet generally. The fillet should not be too large or too small, too small customer aluminium die casting is easy to produces cracks. Too large is easy to produce porosity. Generally, the fillet of custom aluminium die casting is 1 / 2 of the wall thickness ≤ R ≤ the wall thickness; the function of the fillet is to help the metal flow, reduce eddy current or turbulence;


    5Avoid the crack caused by stress concentration due to the presence of fillet on parts;

    When the parts are to be electroplated or coated, the fillet can obtain a uniform coating to prevent deposition at sharp corners;

    The utility model can prolong the service life of the die-casting mould, and can not cause the angle to collapse or crack due to the existence of the sharp angle of the mould cavity;


    (6)Casting slope requirements of custom aluminium die casting design:

    The inclination function is to reduce the friction between the casting and the mould cavity, to take out the custom aluminium die casting easily, to ensure that the surface of the custom aluminium die casting is not strained, and to extend the service life of the custom aluminium die casting mould.

    2.The influence of aluminum die casting parts on electric vehicles

      Aluminum alloy, which has the characteristics of high strength and strong conductivity, can be used for die-casting electric vehicle parts. It can be cast quickly and reliably, for example by a high pressure die casting process. After casting, a suitable alloy must maintain its properties sufficiently to meet the necessary applications. In recent years, the development of aluminum alloy die-casting technology has generally been through continuous optimization and adjustment of the composition of alloy materials, combined with high vacuum die-casting technology and heat treatment process parameter adjustment, to give full play to the process characteristics of alloy materials, with the help of high-pressure injection and low-speed filling continuously improve the comprehensive mechanical properties of die-casting alloy materials.


    3.Electric Vehicle battery housing

      The density of aluminum alloy is 2.7g/cm³, and aluminum alloy has obvious advantages in terms of compression or welding. The density of magnesium alloy is 1.8g/cm³ and that of carbon fiber is 1.5g/cm³. These materials are used to produce battery trays, which will greatly improve the lightweight level of new energy vehicles. As known that the battery housing are mainly uses AlSi10MgFe, ENAC43400, A380 materials for aluminum alloy die-casting. The battery housings die cast from these materials have good plasticity and excellent corrosion resistance, especially no stress corrosion cracking tendency, and good welding performance, making these aluminum materials extremely suitable for the application of this project. In order to ensure the product quality of aluminum alloy die castings, it is necessary to adopt advanced welding technologies such as friction stir welding to ensure that the products are integrated.

      Especially built BEVs use "skateboard"-style platforms, such as Rivian and Volkswagen MEB platforms. Usually, the battery housing is located between the axles, and the motor and control system are installed above the axles.

    Which shows a typical method that uses a grid-type (or egg-shaped carton) structure to fix and protect the battery module within the frame and the lower cover (providing both protection and chassis integrity).


    4.Summary

      Nowadays, the development of electric vehicles is getting better and better, the annual sales are gradually increasing, the popularity of the public is also getting higher and higher, and it brings more and more opportunities to the aluminum alloy die-casting industry.It is believed that the demand for aluminum alloy die castings for electric vehicles will increase in the near future.

    1.Overview of Engine Mounting Bracket

    Engine mounting bracket which is divided into two parts is a component of automobile engine. The first one is torsional bracket, the second one is engine mounting rubber whose main function is fix the shock absorption. Torsion bracket is a kind of engine fastener, which always connected to the engine on the front axle of the vehicle body. It is different from the ordinary engine mounting rubber is that the mounting foot is a rubber pier directly installed in the bottom of the engine, and the torsional bracket is similar to the appearance of an iron bar installed in the side of the engine. There is also a torsional bracket rubber on the bracket, which plays the role of damping.


    2. Overview of car engine bracket

    The car engine bracket is the part that holds the engine in the car. In most cars, the engine and transmission are bolted together and secured together by three or four bases. Part of the car engine bracket is bolted to the body or frame. The other part holds the engine. The engine is a source of vibration because it has many moving and rotating parts. Car engine bracket's job is not only to hold the engine in place, but also to reduce the engine vibration felt in the car. To further suppress vibration, some car engine bracket are filled with liquid and act as shock absorbers. The car engine bracket does not require any maintenance or regular maintenance and needs to be replaced only in the event of failure or wear and tear.


    3. How engine bracket works 

    The working principle of engine bracket is to fix the engine firmly on the subframe or engine base of the car. It is one of several mounts that hold the engine and transmission together and in place. In this way, the metal surface of the engine does not friction with the metal surface of the body, allowing the shock wave to pass through the car, and rubber is used to fill the engine bracket. Some automakers use vacuum control or electromagnetic mounting to further control vibration absorption. Problems occur when the installation material begins to deteriorate.

  • Die casting can be divided into: casting, mold, die casting. Die casting is a precision casting method that uses a high pressure to force a metal solution into a complex metal mold.


    There are many types of die casting, whose process can be divided into casting, mold, die casting.


    What  is die casting? Die casting is a precision casting method that uses a high pressure to force a metal solution into a complex metal mold. Die casting is abbreviated as die casting, which is a casting method in which a molten alloy liquid is poured into a pressure chamber, a cavity of a steel mold is filled at a high speed, and the alloy liquid is solidified under pressure to form a casting.


    Casting dimensional accuracy is high, generally equivalent to 6~7, even up to 4;Good surface finish, generally equivalent to 5~8;

    High strength and hardness, generally higher than sand casting by 25~30%, but extended the rate is reduced by about 70%;The size is stable and the interchangeability is good;The thin-walled complex casting can be die-cast. For example, the current zinc alloy die castings have a minimum wall thickness of 0.3 mm; custom aluminum alloy die casting up to 0.5 mm; the minimum cast hole diameter is 0.7 mm, and the minimum pitch is 0.75 mm.


    Defination of high pressure aluminum casting

    High pressure aluminum casting is a process of pressing molten metal into a sealed mold cavity under pressure. It is held in place by a strong compression force until the metal solidifies. After solidification, the mold is released, opened, and the metal is released. After disassembly, the mold cavity is re-sealed for the next cycle. The stage of exerting extremely high pressure on the molten metal true injection plunger is called strengthening.


    Systems in high pressure aluminum casting

    This process uses two different systems:

    Hot chamber system. The injection system of the hot chamber machine is immersed in the molten metal of the blast furnace. When the piston is pumped, it forces the metal along the nozzle into the mold.

    Cold room system. Generally speaking, small parts are made in hot chamber systems, while large parts are made in cold chamber systems because the size of hot chamber machines is limited. Compared with the hot chamber system, the pressure of the cold chamber system is higher.


    Advantages of high pressure aluminum casting

    Higher production speed. 

    Significantly reduced processing operations. 

    The welding agent has good surface finish. 

    Reducing the total weight of the welding agent can reduce the thickness of the plate wall. 

    The mold is durable, so the cost is reduced. 

    More complex parts can be made, reducing the number of parts required at a time.

    Time Parameter of Die Casting

    Holding Time

    After the molten metal fills the cavity, the casting is completely solidified under pressure. This period of time is called the holding time, and the holding time is related to the wall thickness of the casting and the metal crystallization temperature.

    Retention Time

    The time from the end of the holding pressure to the ejection of the casting from the mold opening is called the mold retention time. The mold retention time is determined according to the nature of the alloy, the wall thickness of the casting, and the structural characteristics. Generally, the minimum time for the die casting manufacturing process to eject without deformation or cracking is appropriate.

    Temperature of Die Casting

    Pouring Temperature

    The average temperature of the molten metal poured into the injection chamber to the filling cavity, also known as the molten metal temperature, is usually at the lowest possible temperature, generally higher than the die-casting alloy, while ensuring the filling and quality requirements. The liquidus temperature is preferably 10~20 °C.

    Die Casting Mold Temperature

    The die-casting mold should be preheated before production, and a certain temperature should be maintained during the die-casting process. The die-casting mold is always in a hot state, which provides a basic guarantee for the filling and solidification of the alloy liquid. The zinc alloy is generally 150~200 °C; the preheating of the die casting mold can avoid the rapid cooling of the molten metal and reduce the fatigue stress of the die casting mold.

    Telecom Cover Parts Overview

    Vehicle telecommunication is often developed as part of the Intelligent Transportation System (ITS). Vehicle telecommunication parts are computer network in which vehicles and roadside units are communication nodes that provide information to each other, such as security warnings and traffic information. They can effectively avoid accidents and traffic congestion. Common telecommunication structures are master-slave transfers and bus transfers.The communication cavity is the main component of the communication component.

    The Communication Cavity is composed of resonator tuning screw and so on. The cavity filter adopts a microwave filter with a resonant cavity structure, and the cavity can be equivalent to an inductance parallel capacitor, thus forming a resonance level and realizing a microwave filtering function. Compared with other microwave filters, it has a firm structure, stable and reliable performance, small size, moderate Q value, far parasitic high-end passband and good heat dissipation performance, being used for larger power and frequency to filter out strong out-of-band interference signals. In general, it is better than other microwave filters.

    During the process of manufacturing telecommunication parts, the main material is aluminum alloy, because it has the advantages of small density, high mechanical strength, good shock absorption performance, excellent casting performance, easy plating and spraying, and good thermal conductivity, corrosion resistance and oxidation resistance.

    As mobile telecommunication systems gradually develop toward high frequencies, RF metal components, as an important internal component of RF devices, will develop toward higher integration and precision, smaller volume, and lighter weight.It is mainly used in telecommunication base station.


    Importance of Telecommunication Parts

    Any organization will have different forms of communication, some face-to-face, others can use technical communication, this is telecommunication, such as e-mail, phone calls, video conferencing, text messages, browsing the web, download and transfer files, these communications use telecommunications systems. Telecommunications system is a collection of nodes and links that realize telecommunications. The nodes in the system are the devices we use to communicate with, such as a telephone or a computer. 

    Telecommunication parts is used to produce these devices. High-quality telecommunication parts is an important guarantee for normal communication, which can ensure the smoothness and stability of communication, as well as the security of communication. Therefore, if you want to maintain normal communication, you need to choose a guaranteed telecom parts.

    Advantages of Aluminium Alloy Die Casting Products

     

    1. The microstructure of aluminium casting parts is compact and has high strength and hardness.

     

    Because die casting is the filling of molten liquid metal in a very short time, it is cooled rapidly in die casting die and solidified and crystallized under high pressure. Therefore, the microstructure of aluminium casting parts near the surface layer is fine and dense, which makes aluminium casting parts have high strength, hardness, good wear resistance and corrosion resistance.

     

    2. Aluminium casting parts have good surface quality and high precision.

     

    The dimensional accuracy of aluminium casting parts can reach the i13-i level, even ir9 level at the highest level; the surface roughness r-value of aluminium casting parts usually reaches o.8-3.2 μm or even O.4 μm. Aluminium casting parts have good interchangeability and can produce aluminium casting parts with complex shapes, clear outlines and thin walls and deep cavities. The minimum wall thickness of aluminium casting parts is 0.5mm. At the same time, it can cast clear characters and patterns.

     

    3. High production efficiency, can realize mechanized or automatic production, especially suitable for mass production.

     

    According to the size of the die casting machine, the cold chamber dies casting machine can die-cast 3100 times per hour, or even more. The hot chamber dies casting machine can die-cast 40-1000 times per hour.

     

    4. High material utilization

     

    Aluminium casting parts can be directly assembled and used without machining or with a small amount of machining, and the material utilization rate can reach 60% ~ 80%, or even higher, which means good economic benefits. Because of high precision, good surface quality, less machining allowance or assembly without machining, machining equipment and cost are reduced, and good economic benefits can be obtained.

     

    5. It can simplify the manufacturing process.

     

    Other inserts with special properties can be directly embedded in aluminium parts in automobile die casting production. It can not only meet the requirements of service performance, expand the use of products, but also reduce the assembly process and simplify the manufacturing process.

     ▲   Die-casting process is the process of unifying pressure, speed and time by using three major elements: die casting machine, die casting mold and material alloy. For metal hot processing, the existence of pressure is the main feature of die-casting technology that distinguishes other casting methods. Pressure casting is a fast-developing special casting method with less cutting and no cutting in modern metal processing technology. It is a process in which molten metal is filled into a mold under high pressure and high speed, and crystallized and solidified under high pressure to form a casting. High pressure and high speed are the main characteristics of die casting. The commonly used pressure is tens of megapascals, the filling speed (inner gate speed) is about 16-80 m/s, and the time for molten metal to fill the mold cavity is extremely short, about 0.01-0.2 seconds.

     ▲   The following is the die casting process:

      1) Raw material: This is the raw material for the production of aluminum alloy die casting ingots.

    aluminum-alloy-aluminum-ingot.jpg

      2) Melting: In order to manufacture aluminum alloy die castings, it must be heated to a certain temperature to melt the aluminum ingot. The general choice of aluminum alloy: 610-700 degrees; different pouring temperatures will affect the mechanical properties and quality. The pouring temperature of aluminum castings should be determined according to specific conditions.

    melting.jpg

      3) Die casting: The molten metal is in a molten state, and the molten metal is filled into the mold under pressure.

    die-casting.jpg

      4) Degating: The sprue sleeve is also called the inlet gate, the in-gate handle, etc., which allows molten aluminum to be injected into the mold.

    degeting.jpg

      5) Deburring: Deburring the die-casting parts, rounding the corners, removing rust and descaling.

    去毛刺2.png

      6) Trimming: Decorative surface finishing to improve functional edges and surface appearance.

    trimming.png

      7) Shot blasting:

          ✧  Able to clean up purposefully, and clean up wherever needed

          ✧  The angle and spray distance of the spray gun can be adjusted to the best position at any time according to the observation of the operator

          ✧  The moving speed of the nozzle of the spray gun relative to the surface of the casting can also be observed by the operator, and the optimal value can be adjusted at any time to minimize the projectile indentation and improve the cleaning effect.

    shot_blasting.jpg

      8) CNC Machining: CNC Machining ,it is set up and adjust on the CNC machine tool, and then the die casting is processed and manufactured.

    CNC_Machining.jpg

      9) Leak test: For products with air tightness requirements, the leak test can quickly identify whether the parts have poor leakage.

    Leakage_Tester.jpg

     10)Cleaning: Cleaning the product directly or indirectly affects the liquid and dirt, disperses, emulsifiers, and peels the dirt layer to achieve the purpose of cleaning. Even without damage to the surface of the product, the deep holes, crevices, and hidden areas of the parts can also be cleaned to make the product shinier.

    ultrasonic-cleaning-machine.jpg

     11)Packaging: After the finished product comes out, it will be fully packaged to prevent damage to the finished product.

    packing.jpg

      ▲   Summary: The casting process of aluminum alloy die castings is to fill the mold cavity with molten metal first at low or high speed. The mold has a movable cavity surface, which is pressurized forged with the cooling process of the molten metal. Eliminate the shrinkage cavity and porosity defects of the blank, and also make the internal structure of the blank reach the forged broken grains. The comprehensive mechanical properties of the blank have been significantly improved. In addition, the rough produced by this process has an outer surface finish of 7 (Ra1.6), which has a metallic luster like the surface produced by the cold extrusion process or machining.

Heat sink enclosure can be customized according to customer drawings.


    Overview of aluminum heat sink enclosure

    Aluminum is light in weight and easy to manufacture. Aluminum alloy is the most common radiator material. The cost of aluminum is lower than that of copper and has high performance-to-price ratio, so it is an ideal choice for most radiators. Its heat transfer capacity, or thermal conductivity, is about half that of copper. This limits the distance at which heat moves and conducts from the heat source in the radiator base. The radiator is designed to maximize the surface area in contact with the coolant.

    With the development of science and technology, people's requirements for the safety and beautiful appearance of die casting products are constantly improving. The evaluation of the quality of the parts is different with different uses. This paper analyzes how the die design affects the quality of aluminium dies casting. How produce high-quality parts is of great significance to save materials, energy, shorten manufacturing hours and improve economic benefits.


    Factors affecting the quality of die casting

    Many factors affect the quality of die casting part, such as the type and quality of the die-casting machine, the geometric structure of die-casting parts, the rationality of technical requirements, the structure of die, the technical level of operators, etc.

     

    1. Design of die casting

    The designer should first fully understand the user's requirements and working conditions, as well as the stress of the die casting. Then the designer chooses the appropriate material according to the use requirements and working environment and understands the die casting performance of the material. In the design, special attention should be paid to making the die casting structure as simple as possible on the premise of meeting the use requirements. The wall thickness shall be proper and uniform, and the necessary die inclination shall be reserved, otherwise, the defects such as pit, air hole, shrinkage porosity, under casting, pull mark, crack, deformation and so on will appear on the die casting. The requirements for dimensional accuracy of die-casting parts should be reasonable, otherwise, it will cause unnecessary troubles to die design, die processing, formulation and management of process conditions, and also cause a large number of unqualified products.

     

    2. Die structure, machining accuracy and die material selection


    Die casting is made by die casting. There is no doubt that the design, processing and selection of die materials are closely related to product quality. If the die structure is unreasonable, no matter what measures are taken from the process, it is difficult to make the product qualified. Also, the quality of the product and the shelf life of the die will be affected by the die material, the processing accuracy, the surface roughness, the processing trace, the micro-crack of the heat treatment, the thickness of the nitriding layer and the improper assembly of the die.

     

    3. Shrinkage of casting materials

    The average shrinkage of casting material is usually selected when it is given in the form of an average percentage or percentage with a certain range of change. For high-precision die-casting parts, we should pay special attention to the material shrinkage when we design the mould. If necessary, we can make a test mould first, and then design and manufacture the mould for mass production after obtaining the required data on the test mould.

     

    4. Formulation and implementation of the die casting process

    The formulation and implementation of the die casting process are related to the quality of die-casting equipment and the technical level of operators. Under the condition of the existing die-casting equipment in China, it is difficult to achieve stable, reliable and accurate control of the die-casting process parameters. The realization of basic control of the die casting process is the process of combining and using die casting equipment, die casting materials and dies. If the process and main parameters are not strictly carried out, the die casting will have shrinkage, deformation, under casting and unqualified dimensions.

     

    Relationship between die casting quality and mould

    Die is the main tool for die casting. Therefore, when designing the die, we should try our best to make the overall structure of the die and the structure of die parts reasonable, easy to manufacture, easy to use, safe and reliable. To keep the die from deforming in the die casting, the molten metal can flow stably in the die, the casting can be cooled evenly, and the die casting can be fully automatic without failure. Besides, according to the production batch, material conditions and other reasonable selection of suitable mould materials.

     

          1. The structure of the mould and its parts should be reasonable

    From the point of view of strength, it is better to design the die parts as a whole. This kind of mould can be firm and durable, not easy to be damaged and deformed in use. However, if the shape of the die-casting is complex and the parts of the die-casting are complex, it will be difficult to process the die-casting and the accuracy of the processing is not high. If the mould parts are made into a combined type, the processing is greatly simplified, and it is easy to obtain high processing accuracy, and then high-quality die-casting parts can be obtained.

     

    2. Influence of cavity number

    To determine the number of cavities, we should consider the equipment capacity, the difficulty of mould processing, the production batch size, the precision requirements of castings, etc. Especially the multi-cavity mould. Because of the difficulty of die machining, the large error of dimension accuracy, and the difficulty of balancing the runner configuration, the performance of each cavity casting may be inconsistent. The first mock exam is required for high precision, so when the geometry is complex, it is best to use one cavity for one mould. Small castings depend on the situation.

     

    3. Design of pouring system

    The gating system is not only the channel for liquid metal to fill the die casting mould but also plays an important role in regulating the flow velocity and pressure transfer of the melt as well as the exhaust conditions and the thermal stability of the die design for die casting. Therefore, it is necessary to analyze the structural characteristics, technical requirements, alloy types and characteristics of the casting to design the gating system. It is necessary to consider the type and characteristics of the die casting machine to design a reasonable gating system.

     

    4. Design of exhaust system

    The mould shall be equipped with an overflow groove and exhaust channel with sufficient overflow range, which is very important to ensure product quality. People often ignore the phenomenon that the overflow channel is blocked up prematurely by the incoming liquid metal. A reasonable structure shall be adopted to make the liquid metal flow into the deeper part of the overflow tank first, to ensure that the vent hole is always open for the longest time. Besides, the overflow tank shall be equipped with an ejector rod to remove the metal in the overflow tank.

     

    5. Mould temperature

    The temperature of the die casting die is an important factor that affects the quality of the casting. Improper mould temperature not only affects the internal and external quality of the die casting (such as porosity, shrinkage cavity, porosity, mucous membrane, coarse grain and other defects), but also affects the dimensional accuracy of the casting, even the deformation of the casting, causes the crack of the die casting, forms the net burrs on the surface of the casting that are difficult to remove, and affects the appearance quality of the die casting. Take the aluminium alloy as an example, the alloy temperature is 670-710 ° C cast into the mould. In the long-term production practice, it is concluded that the best temperature of the mould should be controlled at 40% of the casting temperature. The temperature of aluminium alloy die casting die is 230-280 ° C, which is favourable for obtaining high quality and high yield castings. Generally, the mould does not need gas or electric heating but uses preheating and cooling devices. These devices use oil as the medium according to the requirements to preheat and cool the mould.

     

    6. Dimensions of formed parts

    When calculating the size of the die casting part, the shrinkage of die-casting materials should be in line with the actual situation, otherwise, die casting components produced will be unqualified. If necessary, the size of the die casting shall be calculated after the actual measurement of the test die. For high-precision products, we even need to take into account the thermal expansion of die-casting parts and the influence of preservation and use environment on the dimensional accuracy of products after die-casting.

     

    7. Influence of dying joint position

    The position of the parting surface will affect the mould processing, exhaust, product demoulding, etc.

    Generally, the parting surface will leave a trace line on the product, which will affect the surface quality and dimensional accuracy of the product.

    Therefore, in the design of the parting surface position, in addition to considering product demoulding, mould processing, exhaust and other issues, we can place the parting surface position where the product surface quality requirements are not high or the dimensional accuracy is not high.

     

    8. Mould deformation effect

    Friction welding overview

    Friction welding is a pressure welding method that uses the heat generated by the relative frictional movement of the weldment to achieve reliable connection of materials. 

    The welding process is under the effect of pressure, the friction between the materials to be welded increases the temperature of the interface and its vicinity and reaches in the thermoplastic state, with the action of upsetting force, the interface oxide film is broken, the material undergoes plastic deformation and flow, and the joint is formed by the interface element diffusion and recrystallization metallurgical reaction.

    EMP Tech Co., Ltd, offering professional friction welding services, can finish many kinds of friction welding, including the continuous drive friction welding, rotational friction welding and orbital friction welding, etc..


    Friction welding aluminum

    The surface temperature of friction welding is the temperature of the heat source of friction welding, which will directly affect the heating temperature and temperature distribution of the joint and the deformation and diffusion of the joint metal. In the process of friction heating, the friction surface can also adjust the friction heating power through the influence of the friction coefficient, so that the heating power and the temperature of the heat source are in balance. Welding test and production practice show that when the diameter of the workpiece increases, the rotation number increases and the friction pressure increases, the temperature of the friction welding surface increases. Otherwise, the surface temperature of friction welding will be reduced.


    Friction welding services overview

    Heating deforms the material, and the rotating tool stirs the material at the weld. In this way, friction welding technology creates a uniform structure with excellent performance. The whole process is emission-free. When welding must be very tight, friction welding is the preferred method. It can connect the workpiece with repeatable pressure and medium seal. Friction welding can be optimized and integrated into industrial batch production. The result is top quality that is easy to copy.


    Friction Welding


    As a machinery parts manufacturer, we provide various products and services in this area, and actually friction welding services and production, continuous drive friction welding, phase-controlled friction welding, inertial friction welding and friction stir welding are more common used.


    Advantages of friction welding services

    Durable, medium-sealed and pressure-sealed welds.

    Height, repeatable seam quality.

    Low warping joint.

    No pores or hot cracks.

    No exhaust emissions, no shielding gas, powder, welding wire and other auxiliary materials.


    Friction Welding


    In actual friction welding services and production, continuous drive friction welding, phase-controlled friction welding, inertial friction welding and friction stir welding are more common.

    Friction welding machine is mainly used for welding of medium-sized shaft parts. It can weld a wide range of metals, and has the characteristics of stable performance, high production efficiency and low energy consumption, which is important for friction welding companies.


    Orbital friction welding

    Rail friction welding is similar to rotary friction welding, but the two welding parts of rail friction welding rotate in the same direction and at the same speed,with axes offset up to 3 mm. At the end of the welding, the two parts return to the common shaft, the relative motion ends, and the welding relay remains intact or increases. Rail friction welding has the advantage of uniform surface velocity in the whole contact zone. You can connect non-circular components and multiple individual parts in a friction welding sequence. Although rail friction welding has been demonstrated in many materials and joint configurations, it is rarely used in industry.

    The quality of aluminum die castings has a great impact on the performance of automotive and mechanical parts. For example, the sizes of the impellers, casings and inner parts of various types of pumps, the accuracy of the profile and surface roughness directly affect the working efficiency of pumps and hydraulic systems, energy consumption and the development of cavitation. The strength and resistance to coldness and heat of cast aluminum parts such as cylinder blocks, cylinder heads, cylinder liners, piston rings, and exhaust pipes will directly affect the engine's working life.

     

    So how do we check the quality of aluminum die castings?

     

    You may follow the below procedures to check the quality of aluminum die castings:

    1. Aluminum alloy composition analysis with spectrometer ;

    2. Analyze the crystallization of castings with metallographic analyzer;

    3. Detect the internal quality of the casting with X-ray flaw detector

    4. Check whether there are cracks on the casting surface with Fluorescence analysis;

    5. Detect the mechanical properties of castings with universal testing machine

    6, Check the size of the measurement with calipers, height rulers, three-coordinates for dimensional detection of castings, and so on.

    1. Visual inspection method of aluminum alloy die casting

     

    We usually use visual inspection. Visual inspection conditions: under the approximate natural light of 300-600lx natural light (such as the distance between 40W fluorescent lamp and 500mm). The distance between the examiner and the target is 600-650mm, and the viewing angle is 45-90 °. The visual acuity level of the examinee should be above 1.0 (including after correction).

     

    2. Common appearance quality problems of aluminum alloy die casting

     

    (1) Die sticking

     

    Along the direction of demoulding, due to the adhesion of metal, the manufacturing slope of the mold is too small, resulting in the scratch marks on the surface of the casting, which is called the scratch surface when it is serious

    The global die casting manufacturing centre is transferred to the mainland of China. China's precision dies casting enterprises are mainly distributed in Guangdong, Jiangsu, Zhejiang, and other places. Most of the large-scale and specialized enterprises are concentrated in the Pearl River Delta and the Yangtze River Delta. Due to the dominant position of Asia, especially China, in market demand, raw material supply, labour resources, industrial chain supporting, policy support, and the rapid development of China's automobile industry, since the 21st century, the global die casting production has shown a trend of transfer to Asia, especially to the mainland of China, which is still continuing. The expansion of market scale and the entry of international excellent enterprises have promoted the technical level and management level of domestic die casting manufacturers, and further promoted the development of the industry. China has formed the Yangtze River Delta, Pearl River Delta, northeast three provinces, southwest region and other pressure casting industrial clusters, of which the Yangtze River Delta and the Pearl River Delta are the most prominent. The two regions have an active economy, developed supporting industries and obvious regional advantages.


    Advantages of Aluminium Parts in Automobile

    Under the premise of ensuring vehicle strength and safety performance, vehicle lightweight can improve vehicle power, reduce fuel consumption and exhaust pollution by reducing vehicle quality. Reducing the mass of different parts such as body, interior, and exterior decoration, power system and so on will help to reduce the energy consumption in the process of driving. Aluminium parts in automobile is light, recyclable and easy to form, so it is widely used in automobile body and parts. In theory, automotive aluminum parts can reduce the weight of steel cars by as much as30% - 40%, of which aluminium engine can reduce 30%, the aluminum radiator is 20% - 40% lighter than copper, the all-aluminium body is 40% lighter than steel, and aluminum hub of the automobile can reduce 30%. Therefore, aluminum alloy material is an ideal material for automobile lighting.


    Reducing the vehicle weight can reduce the engine load, improve the driving performance of the vehicle, effectively reduce the braking distance, make the steering and bending process more flexible so that the vehicle is more stable, and the aluminum alloy structure can absorb and disperse more energy when impacted, so it is more comfortable and safe. As a result, in the next decade, the aluminum penetration rate of all major parts of the car will be significantly increased, and the penetration rate of the aluminum engine hood is expected to increase from48% in 2015 will increase to 85% in 2025, and the penetration rate of aluminum doors will increase from 6% in 2015 to 46% in 2025. Specifically reflected in the average aluminum consumption per vehicle in North America in 1975, the average aluminum consumption per vehicle in North America was 38kg, which increased to 180kg in 2015. In 40 years, the aluminum consumption per vehicle in North America continued to increase, with a compound growth rate of 4%. It is estimated that China will achieve 190 kg/vehicle aluminum consumption in 2020, which is in line with North America, with a corresponding market space of about 152 billion yuan.


    The concentration of the die-casting industry in China is relatively low. There are about there are more than 12000 enterprises, of which more than 70% are die-casting enterprises. The enterprises are mainly distributed in Guangdong, Jiangsu, Chongqing, and other places. Most of the large-scale and specialized enterprises are concentrated in the Pearl River Delta and the Yangtze River Delta, and the proportion of large-scale die-casting enterprises is only about 10%. There are two main types of domestic enterprises with a large production scale of automobile die-casting, one is the supporting enterprise in automobile field, which is subordinate to the group company of downstream industry; the other is the independent automobile precision die casting production enterprise, which is specialized in the production of automotive casting components, and has established a relatively stable long-term cooperation relationship with downstream customers.

    Surface treatment overview

    Surface treatment is a process for artificially forming a surface layer on the surface of a base material that is different from the mechanical, physical, and chemical properties of the base body. The purpose of surface treatment(E-coating/KTL) and finishes is to meet the requirements of product's corrosion resistance, wear resistance, decoration and other special functions.


    KTL surface treatment

    KTL provides products with long-term anticorrosion, high resistance to mechanical damage, salt water resistance and chemical resistance. 

    During the KTL process, the product is completely immersed in a liquid-colored KTL bucket, soaked through an anode and placed on both sides and bottom of the KTL, and charged with a positive electrode. 

    In this process, the immersed product is connected to the negative electrode and acts as the cathode. 

    KTL is used as the final coating or primer under the paint and is suitable for all products and their initial sandblasting, providing the highest quality surface treatment.

    Preheating requirements of cast aluminum mold casting in process

    Die casting aluminum parts  It is necessary to preheat the casting aluminum die before die casting. The unheated die will make the aluminum liquid cool too fast and reduce the fluidity, making the casting easy to have problems such as cold separation, incomplete moulding, inclusion, porosity, etc. At the same time, the mold is strongly impacted and the stress is doubled, which makes it easy to be destroyed. Therefore, preheating can improve the surface quality of castings and prolong the service life of dies.

    Generally, the preheating temperature is controlled at150 ℃ ~ 300 ℃, and it can be used after holding for about 0.5h.

    Do not use molten metal(aluminum water) directly to preheat the mold, because if the cold mold directly contacts the hot liquid metal, it is bound to be impacted by heat, resulting in thermal erosion, accelerating the surface cracking and peeling of the mold caused by thermal fatigue.


    Cooling requirements of cast aluminum moldcasting in process

    In the continuous die casting production, the temperature of the aluminum mold often increases. The high temperature not only causes the liquid metal to bulge but also causes the slow cooling of the casting, resulting in the coarse grain and the decline of the quality of the high pressure die casting aluminum. Therefore, when the mold temperature is too high, cooling measures should be taken.

    (1) Water cooling: a cooling water channel is arranged on the aluminum alloy die-casting die to make the circulating water flow into the forming insert or core and bring the heat out of the die. The cooling efficiency of water-cooling is high, which can effectively reduce the temperature of the cavity surface, but increase the complexity of die-casting mold structure, mainly used for mold with large heat dissipation. In order to prevent condensation on the surface of the cavity, the temperature of the cooling water should be higher than the room temperature.

    (2) Air cooling: for the parts that are difficult to be cooled by water in the die casting mold, air cooling can be adopted, and blower or compressed air can be adopted for air cooling. Air cooling can not only cool the aluminum alloy die-casting mold, but also blow the coating evenly, disperse the volatile gas of the coating, and reduce the porosity of the casting. The cooling temperature of air cooling is much lower than that of water cooling.

    (3) Heat pipe cooling: mainly used for small parts that are difficult to be directly cooled by cooling water. In the small parts to be cooled, the heat pipe is used to export the special heat, and then the cooling water is used to cool the heat pipe.


    Storage management after using

    After the use of the aluminum mould, the mold cavity shall be cleaned in time to effectively remove the residual aluminum. After the cooling, the rust prevention treatment shall be carried out, and the mold shall be put in storage and placed horizontally for centralized management for reuse. The service life of aluminum mold can be effectively extended by grasping the relevant links of die cast tooling, manufacturing, use and maintenance management.

    Cast aluminum is a process in which molten aluminum is poured into a mold and cooled to form aluminum parts in the desired shape. Castings obtained by casting aluminum are called aluminum castings.

    During the casting process, aluminum castings are prone to defects such as internal looseness, shrinkage, and porosity. these castings with defects are after machined, the surface dense layer components are removed, but the internal tissue defects are exposed.


    Defective appearance:

    Casting crack: It is a crack formed at a higher temperature. It is easy to appear when the volumetric shrinkage of the casting is large and the thermal expansion coefficient is large.

    Heat treatment cracks: Due to overheating or overheating caused by heat treatment, often showing trans-crystalline cracks.

    The causes of cracks and suggestion:

    1. The structural design of the casting is unreasonable, with sharp corners, and the thickness of the wall changes too much. If cracks occur in this case, the structural design of the casting should be improved to avoid sharp corners, and strive to strengthen wall thickness and smooth transition.

    2. Cracks can also occur in sand molds (cores) with poor yielding properties. Measures should be taken to increase the concession of the sand mold (core).

    3. Partial overheating of the mold will cause cracks, and it should be ensured that all parts of the casting are solidified simultaneously or sequentially, and the design of the pouring system is improved.

    4. If the pouring temperature is too high, cracks will also occur, and the pouring temperature should be appropriately reduced.

    5. When the casting is taken out from the casting mold too early and the casting will be deformed, the thermal correction method should be used. The cooling time of the mold should be controlled.

    6. The heat treatment is overheated, and the cracks are generated after the cooling rate is excessively exciting. The thermal correction method is used when the casting is deformed. Correctly control the heat treatment temperature and reduce the quenching cooling rate.

    Compared with other materials, aluminum alloy has many advantages, such as high strength and good corrosion resistance, which makes it widely used in civil and industrial fields, and has become the first choice of metal materials in the field of electronic and electrical, transportation and other fields.


    The application status of aluminum alloy products

    (1) Application of aluminum alloy in the field of transportation

    Nowadays, the key issue in the field of social transportation is energy conservation and environmental protection, but choosing aluminum alloy is an effective way to achieve this goal. Therefore, since 1980, aluminum alloy materials have become the main materials in the transportation industry. At present, the use of aluminum alloy materials in the transportation industry has exceeded 25%, among which the use of aluminum alloy materials in the automobile industry has exceeded 15%, which has gradually become the largest field of aluminum alloy materials in the world.


    Aluminum alloy has good impact resistance, vibration resistance, tensile resistance and other mechanical properties, so as to meet the relevant standards of materials selection for automobiles and high-speed trains. In addition, the compactness of aluminum alloy material is only that of steel material33%, which reduces the weight of the car itself, reduces driving resistance, and thus saves fuel consumption.


    Moreover, aluminum alloy itself has better wear resistance and corrosion resistance, without rust removal, which greatly reduces the maintenance cost and manufacturing cost. What's more, compared with traditional steel, aluminum alloy is more convenient for recycling. Generally, the recovery value of an end-of-life car is  6 times as high as a steel car. Therefore, aluminum alloy is widely used in motorcycles, trains, high-speed rail, subway and other vehicle structural parts and air conditioning, as well as skin and armour plates of different types of yachts and cruisers. In recent years, with the continuous development of high-speed railway construction in China, all aluminium alloy structures are used in high-speed railway bodies. 6xxx series aluminium alloy with high strength is often selected for the body frame in the field of automobile materials.


    (2) Application of aluminum alloy in the aerospace

    In 1972, Alcoa successfully developed a new type of 7075 alloy by using Ti, Mn and other trace elements, and the application of aluminum alloy in Boeing 747 aircraft successfully opened the prelude of large-scale production of aluminum alloy in aircraft. At present, aluminum alloy has become the first material for spacecraft and aircraft lightweight. In civil aircraft structure, the aluminum alloy consumption is about 76%, for example, the aluminum alloy consumption of Airbus A380 is about 71%.


    At present, almost all kinds of aluminum alloys in the market can be put into the aerospace field. becauseAl-Zn-Cu has high strength and good machinability, which is often applied to aircraft structural materials, such as stressed structural parts and frames, etc. Al-Li alloy is widely used in the manufacture of low-temperature fuel tanks for rockets and aircraft because of its low density and good low-temperature toughness.


    (3) Application of aluminum alloy in the electronic and electrical field

    Today,  there is about 6% of annually produced aluminum in the world are used in the field of electronics and electrics, while aluminum alloy is the main electronic conductor. After all, first of all, the price of aluminum alloy is far lower than that of copper alloy, which can strictly control the cost of laying cables. Secondly, because the compactness of aluminum alloy is lower than that of copper alloy, aluminum alloy can obtain the required conductivity on the basis of light and heavy, and significantly reduce the transportation cost. In addition, the recovery rate of copper alloy is lower than that of aluminum alloy, and it has high corrosion resistance, which can reduce the maintenance cost. At present, aluminium-clad steel cored aluminum strand is commonly used in high-voltage transmission lines. This type of aluminum alloy has the characteristics of high strength and good conductivity. There is also a great demand in the field of home appliances, computers and so on, especially the disk substrate of computers, packaging materials of home appliances and so on.


    Future development trend of aluminum alloy products

    With the development of science and technology and economic globalization, I believe that in the near future, aluminum alloy industry can get rapid development, and began to replace the position of steel, its development trend is mainly reflected in the following aspects.

    (1) Optimize the production capacity structure, focus on corrosion resistance, financial, human and material resources and other products with better performance, so as to meet the needs of transportation, electrical packaging and aerospace fields.

    (2) Develop aluminum matrix composites. Under the premise of the properties of the original alloy, many new aluminum matrix composites have better physical and mechanical properties, which is also the main way for future development and research.

    (3) With the development and popularization of aluminum alloy comprehensive utilization technology, regeneration technology and recovery technology, the recovery rate is increasing.

    (4) Innovate process equipment, improve production and processing methods, improve the production quality of aluminum alloy, and speed up production.

    With the rapid development of China's economy, especially the machining and cutting functions, the development of aluminum alloy die casting is becoming more and more mature. But the impact of heat treatment of aluminum alloy die-casting mold on product performance is also crucial.


    1. Quenching cracking. The reasons for quenching cracks are generally due to improper design, overheating, decarburization, improper cooling, and poor quality of the mold steel.


    2. Insufficient hardness. Generally, the lack of hardness of the die-casting mold is caused by the incorrect method of putting the mold parts into the cooling groove. Excessively high quenching temperature, excessive tampering, improper cooling, and decarburization are also causes of insufficient hardness.


    3. Deformation exceeds the controllable range, mainly related to heat treatment.


    4. Insufficient toughness. The reason for the lack of toughness may be that the quenching temperature is too high, and the holding time is too long to cause the grain coarsening, or because the tempering brittle zone is not avoided for tempering.


    5. Grinding cracks. When there is a large amount of residual austenite in the mold parts, under the action of grinding heat, a tempering transition occurs, thereby generating tissue stress, which causes the mold parts to crack.

    X-Ray testing is the best nondestructive inspection method for detecting internal defects of castings can be examined to verify the internal structure and integrity of the specimen.The casting absorbs part of the radiation, and the remaining portion of the radiation exposes the radiographic film. Dense material withstands the radiation penetration, so the film is exposed to a lesser degree in those areas, giving the film a lighter appearance. Less dense materials allow more penetration and correlates to darker areas on the film. Any hole, crack or inclusion that is less dense than the casting alloy is revealed as a dark area.

    The application of die castings is widely used in all walks of life, and there is a huge demand in the market. However, during the production process, the problem of scratches on aluminum alloy die castings are easy to produce, and serious situations will cause scratches.



    Reasons for the drag marks on aluminum alloy die castings:

    1. The mold temperature is higher than 220 degrees, and castings are prone to scratches or sticky aluminum.

    2. The iron composition of the aluminum alloy is less than 0.6%, and the aluminum material has an affinity with the mold, which causes the casting to be scratched or sticky.

    3.  The ejection of the casting is not parallel, causing the casting to be pulled or deformed.

    4.  The surface of the mold core is rough, resulting in a strain or rough surface of the casting.

    5.  The draft angle of the casting core and wall is too small, which causes the casting to be scratched during the mould parting.

    6. Insufficient spraying of the parting agents can also cause drag marks.

    Aluminum metal and aluminum alloys have good fluidity and plasticity, but they tend to turn black during use. Why? The following are the reasons for the blackening of the surface of aluminum alloy die castings:



    1. Unreasonable process design

    The aluminum alloy die-casting parts are not handled properly after cleaning or pressure inspection, which creates conditions for the aluminum alloy die-casting parts to turn black and accelerate the generation of mildew.



    2. Improper storage management

    When the aluminum alloy die castings are stored at different heights in the warehouse, the moldy conditions are also different.



    3. Internal factors of aluminum alloy

    Many aluminum alloy die-casting manufacturers do not do any cleaning treatment after die-casting and machining processes, or simply flush with water, they cannot be thoroughly cleaned, and the surface of die-cast aluminum has corrosiveness such as mold release agent, cutting fluid, saponification fluid, etc. Substances and other stains, these stains accelerate the speed of black mold spots of aluminum alloy die castings.



    4. External environmental factors of aluminum alloy

    Aluminum is an active metal, which is easily oxidized to become black or mouldy under certain temperature and humidity conditions, which is determined by the characteristics of aluminum itself.



    5. Selection of cleaning agent is not appropriate

    The selected cleaning agent is highly corrosive, causing corrosion and oxidation of die-casting aluminum.

    In the automotive industry,some automotive aluminum parts are made of zinc and aluminum alloys die casting. The effects of impurities in the alloy, that the tooling and equipment may cause the internal defects of the casting. Some defects such as porosity, shrinkage holes, and loose tissues are difficult to detect with the naked eye. The existence of the defects will lead to the risk of leakage of the sealed performance and increase the wear of machining tools, and at the same time add extra production costs. The increase makes it difficult to guarantee product quality. To solve the problem of die casting high rejection rate, the "impregnation" process is adopted for remedy.
    Therefore, impregnation technology has been very mature since the 1970s. The application rate of this technology has reached 95%. The impregnation can be infiltrated with the small shrinkage holes and air holes in the casting to enhance the compactness of the die casting parts.

    To meet our customer requirement and improve the die casting parts’quality, EMP Die Casting can provide the impregnation services, leakage testing of aluminum casting, also we could offer FREE Technical Analysis on the die casting parts design, if you might require this, we are glad to support your projects at anytime.

    1) What is the cold shut of aluminum casting parts?

      The gap where metal flows butt or overlap but not merge is called cold shut. The main feature is the obvious, irregular, and sunken linear lines, the shape is small and narrow, and some junction edges are smooth and may be broken. The area where the cold shut occurs in aluminum alloy die castings are usually the area far from the gate. It is due to the fact that when the metal flow is divided into several strands, the flow front of each strand has been in a condensed state (called the solidification front), but under the push of the subsequent metal flow, it is still filled. When the metal stream that it meets also has a solidification front, the solidified layer that meets can no longer be fused, and the joints appear gaps. Severe cold shut has a certain hindrance to the use of castings, which should be determined by the use conditions of the castings and the type of cold shut.


    2) Why the cold shut will be caused in aluminum die casting parts:

    • The molten metal pouring temperature is low or the mold temperature is low.

    • The alloy composition does not meet the standard and the fluidity is poor.

    • The molten metal is filled in separate runners, resulting in poor fusion.

    • The gating design is improper and the filling process is too long.

    • Low filling speed or poor exhaust.


    3) How to improve the cold shut:

    • Properly increase the pouring temperature and mold temperature.

    • Change the alloy composition to improve fluidity.

    • Improve the gating system, increasing the speed of the inner gate, and improving the filling conditions.

    • Improve the overflow conditions and increase the overflow flow.

    • Increase injection speed and improve exhaust conditions.

    • Increase the specific pressure.

    In the year 2015, China produced 45.6 million metric tons of castings in total, followed by India (10.8), the US (10.4), Japan (5.4), and Germany (5.3). With 45 % of the total world casting production, China is the globally leading metal casting nation and has also become the nation with the largest die casting production worldwide. According to FICMES, China’s foundries produced 3.7 million tons of die castings in 2015. About 70 % of die castings are used for automobiles and motorcycles. Over the last 20 years, the average annual growth rate in the Chinese die casting industry has been around 13 % and thus higher than the average growth of the country.

  • 1) What’s the shrinkage porosity? Shrinkage and shrinkage porosity usually occur inside the casting, which is one of the common defects in the formation of aluminum alloy die castings. Shrinkage poro...

    1) What’s the shrinkage porosity?

     Shrinkage and shrinkage porosity usually occur inside the casting, which is one of the common defects in the formation of aluminum alloy die castings. Shrinkage porosity of aluminum alloy die-castings generally occurs in thick parts at the root of the riser near the inner runner, wall thickness transition points, and thin walls with large flat surfaces. The fracture of aluminum castings in the as-cast state is gray, light yellow, and grayish-white, light yellow, or gray-black after heat treatment. On the X-ray film, it is cloudy and severely filamentous. Shrinkage can be found by X-ray.


    2) The reason for shrinkage porosity:

    • During the solidification process, the casting cannot be supplemented from the aluminum distributing liquid and form holes.

    • The pouring temperature is too high, and the mold gradient distribution is unreasonable.

    • The injection ratio is low and the boost pressure is too low.

    • The inner gate is thin, the area is too small, and it solidifies prematurely, which is not conducive to pressure transmission and liquid metal feeding.

    • There are hot spots or cross-sections in the casting structure that change drastically;

    • The amount of molten metal pouring is too small, the remaining material is too thin, and it cannot be used for feeding.


    3) How to improve the shrinkage porosity:

    • Lower the pouring temperature and reduce the shrinkage.

    • Increase the injection pressure and boost pressure to improve the compactness.

    • Modify the inner gate to make the pressure better, which is conducive to the feeding effect of liquid metal.

    • Change the structure of the castings, eliminate the metal gathering parts, and make the wall thickness as uniform as possible.

    • Speed up the cooling of thick parts.


  • Due to the discussions about the future of the combustion engine in general and the diesel engine in particular, many die casting foundries have to adjust to profound structural changes on the demand ...

    die-casting.jpg


    As electric cars penetrate the market there is also likely to be an increase in the demand for lightweight castings.

     

    Under these circumstances, die casting offers ideal opportunities and can exploit its capabilities in a lot of applications, whether for optimized components for the control of traditional engines or for structural parts and components for electric drive systems.

     

    New energy vehicles use more aluminum than fuel/traditional cars. The rapid development of China's new energy vehicles will definitely promote the potential of aluminum parts in the new energy vehicle segment. An EMP is also seizing this opportunity to develop high-performance, highly applicable aluminum materials or deep-processed aluminum components to meet the diverse application needs of new energy vehicles, such as battery housing, motor housing, the motor controller housing, etc, which is our main products with mature engineering that can support our customers.

    Aluminum die casting parts are usually coated for appearance and anti-corrosion requirements. However, some factors will affect the quality of the coating, and even reduce the adhesion of the coating, affecting the performance of the castings.


    1. The grease and release agent are not removed completely

    For aluminum alloy products, special environmentally friendly degreasing agents should be selected. Common degreasers have little effect on mold release agents and can damage the surface of the material, and even cause discoloration of the product surface.


    2. The thickness of the passivation film should be moderate

    The trivalent chromium passivation film is uniform and dense, which can well enhance the adhesion between the coating and the substrate. However, care should be taken during the operation, and the film should not be too thin or too thick. If the film is too thin, the passivation effect will be poor; if it is too thick, the adhesion will decrease.


    3. The quality of washing

    Water washing after passivation is critical. Incomplete water washing can easily produce a secondary film on the surface of the passivation film, which also affects the adhesion of the coating.


    4. The thickness of the coating

    The thickness of the spray should be uniform, and attention should be paid to dust and wind during coating.


    5. The baking temperature

    The temperature in the oven should be constant and should not be hot or cold. If the temperature is too low, the coating will harden poorly, the adhesion will be poor, and the surface will be sticky; if the temperature is too high, the paint will be easy to age and crack.

    The outbreak of Novel Corona Virus in 2020 affects the work and life of all Chinese, which makes this Spring Festival a little "special."


    To prevent the virus and start resumption of work. EMP DIE CASTING has formulated strict epidemic prevention and control measures. It is still in a critical period of the prevention and control of the new crown pneumonia epidemic,the employees' physical health and livelihood are top priority before company's resumption of production. EMP Die Casting Company prepared the masks and medicinal alcohol to give out to employees, anyone who walks into the factory will have to be disinfected with medicinal alcohol. Employees must report their physical conditions and where they have been in the past 20 days before they come to work, employees who returned from other cities consciously quarantine themselves for 14 days. Moreover, everyone’s physical conditions will be recorded and reported to the government every day.


    On February 20, when we walked into the production workshop of EMP DIE CASTING,the aluminum die casting machine roar as usual, the workers on the production line all wore masks as required and were busy at their respective operating stations. The cleaning staff performs disinfection twice a day. Production and virus prevention are proceeding in an orderly way.


    At present, all production lines and workshops are operating at high efficiency as usual. Until now we have resumed work for one week, with a daily output of 20,000 pieces aluminum die casting auto parts.


    Due to the impact of the epidemic, many auto parts projects have been delayed. To resolve these delayed projects, we have readjusted our production plan, we are determined to clear all delayed projects within 15 days, and we will report production progress to customers during the process. We will also arrange shipment as soon as possible after production is completed to minimize the loss to our customers.


    Aluminum die casting parts quality inspection is also our top priority besides the delivery time. We added some procedures to the previous produce quality inspection. Firstly we’ll sterilize the warehouse to ensure the environment is clean. Secondly, we started inspection and packaging after the die casting parts and packaging materials are thoroughly cleaned and disinfected. All procedures are strictly monitored for customers’ concerns.


    Winter comes, can spring be far behind? Although epidemic prevention still faces some challenges. However, all of our employees are united to protect the health of all and the company's smooth production with effective measures and warm actions with the responsibility of the company. We believe we can win this "war."

    Casting post-treatment is the last process in aluminum casting production, which exerts important influence on the quality. But different post treatment has different corresponding effect. For example, heat treatment is used to improve or change the original structure of aluminum casting to eliminate the internal stress, ensure casting performance and prevent casting deformation and damage.


    The heat treatment of aluminum casting aims at different working conditions, generally including quenching, annealing, normalizing, as-cast quenching and tempering, artificial aging, stress relieving, softening and graphitization, etc. For example, casting requires high wear resistance and sufficient toughness whose internal structure should be austenite. For this reason, it is necessary to quench the casting that can be heated to the austenite region to make it completely austenitic, and then quenched and chilled quickly so that the austenite has no time to change and keep down.


    The post-treatment of aluminum casting is divided into three aspects: correction, repair and surface finishing.

    1. Correction

    Because some castings will be deformed in different degrees during solidification, cooling and heat treatment, making some dimensions are out of tolerance. It is necessary to repair them by means of correction. Correction is mainly carried out at normal temperature or warm state by mechanical force. When the deformation is too large, high temperature correction can also be carried out in the heating furnace by casting dead weight or external pressure weight.

    2. Repair

    The external defects of aluminum castings are mainly repaired by welding.

    3. Surface finish

    Casting surface roughness and unevenness are generally polished by suspension and high-speed grinding wheels.

    • What is Water Pump?

    There are multiple watercourses in automobile engine cylinders for cooling water circulation connected with the radiator (commonly known as water tank) placed in the front of the car through the water pipes, forming a large water circulation system. At the outlet on the engine, there is a water pump driven by a fan belt, pumping out the hot water within the engine cylinder waterway and pumping the cold. There is a thermostat beside the water pump. When the car has just started (cold), not open, making the cooling water without the water tank only circulate within the engine cycle (commonly known as small cycle). While the engine reaches above 95 degrees, it is opened, with hot water pumped into the water tank. The cold wind blows over the water tank when the car moves forward, taking away the heat.

    advantages-of-die-casting.jpg


    Compared to many other manufacturing processes, die-casting has advanced advantages that can produce cost-effective parts and high yields.

     

     

    1) Good product quality

    Due to the rapid heat conduction and metal cooling of the die casting mold and the crystallization under pressure, the casting has a fine grain structure and a solid surface, thereby improving the strength and hardness of the casting. In addition, the castings are stable in size and interchangeable, so thin-walled complex parts can be produced.

     

     

    2) High-speed production

    Die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required.

     

     

    3) Good economic benefits

    The machining allowance for die castings is small. Generally, only finishing and reaming can be used, which can save a lot of raw materials, processing equipment and time.

     

     

    4) high precision

    Aluminum die casting can meet the requirement of high precision, which can reach the tolerance to 0.01mm.


    (5) Convenient to use inserts

    It is easy to set up a positioning mechanism on the die-casting die, which is convenient for embedded casting inserts and meets the local special performance requirements of die-casting parts.

    The aluminum casting in the production process mainly refers to aluminum or aluminum alloy equipment obtained by casting. Aluminum or aluminum alloy parts of various shapes and sizes are often called aluminum die castings. The production method of aluminum castings also determines their service life or quite a long lifespan. In order to extend the service life of aluminum castings, the following points should be noted both in production and in use:


    1. The nitration case should not be too deep if choosing nitriding; Turn off the coolant when the surface of the model is at a high temperature. Reduce the temperature of liquid aluminum as much as possible; Spray release agent.


    2. Quenching and cooling must be fast enough after proper heat treatment; The surface of aluminum castings should not be highly polished; Stress relief and tempering should be carried out after a certain amount of die casting. Use inserts whenever possible.


    3. The distance between the cooling watercourse and the surface as well as the corner should be large enough; The jet speed of polymetallic liquid should not be too fast. Mold wall thickness and other dimensions should be designed reasonably.


    aluminum-casting


    4. Preheat the mold to the recommended temperature in the correct way; Stress relief and tempering after rough machining; Oxidation treatment of mold surface; The choice of corners.


    5. Remove the electro spark layer by grinding; Make sure mold is properly cooled; The cooling water is kept between 40 and 50 degrees Celsius; Slow hammers are used when casting 5 to 10 pieces of aluminum. In case of a temporary shutdown, set the mold as far as possible and reduce the cooling water to avoid thermal shock when the mold is restarted.

    • Temperature

    The casting process should be strictly controlled during the use of automobile die casting. Decrease the casting temperature and injection speed and improve the preheating temperature of the die as far as possible within the process permission. The lifespan of aluminum dies casting can be improved greatly once the preheating temperature is increased from 100 ~ 130℃ to 180 ~ 200℃.

    • Welding Repair

    Welding repair is a common method in mold repair. Prior to welding, command the steel pattern number of the welded mold and eliminate the surface defects by machining or grinding. The welding surface must be clean and dried. The welding rod used should be the same as the mold steel and must be clean and dried. The mold is preheated with the electrode (H13 is 450℃), and after the surface is consistent with the core temperature, the mold is repaired by welding under the protective gas. During welding, reheating occurs when the temperature falls below 260℃.


    After welding, when the mold is cooled to be touchable, it is reheated to 475℃ and is kept warm by 25mm/h. Finally, it is completely cooled in still air, and then the cavity is trimmed and finished. After welding, the die is heated and tempered, which is an important link in welding repair, that is, the elimination of welding stress and the tempering of the thin layer under the welded layer that has been quenched during welding.

    In the automotive industry today, traditional New Energy / Electric Vehicle (NEV/EV) battery packs typically adopt steel-framed battery pack structures to meet various puncture-proof, explosion-proof, and load-bearing performance requirements borne by industry and governmental regulations.

    While the steel frame delivers excellent performance for these required tasks, ultimately, one area where it hinders the performance of the NEV/EV is in overall vehicle efficiency. Because the steel-framed structure is very heavy it increases the weight of the vehicle, which directly affects its rolling resistance. Higher rolling resistance for the vehicle means higher energy requirements to get the vehicle up to speed, as well as maintaining steady-state cruising.  

    Because of this, researchers have been looking for ways to increase the overall efficiency of the NEV/EV by reducing the weight of the battery pack. One of the directions researchers have been exploring has been in the use of novel lightweight aluminum alloy battery pack enclosures formed with high-pressure die-casting.

    EN AC-43500, (or AlSi10MnMg for the EN chemical designation), is the main aluminum alloy currently used in the formation of structural parts and subassemblies that have high mechanical performance requirements in the automotive chassis. This alloy, mainly used in the oil pan, sunroof & convertible roof subassemblies, front axles, engine mounts, suspension mount assemblies, multi-component subframes, etc. The following table compares the physical properties of AlSi10MnMg and other aluminum alloy materials.



    In the as-cast condition, the strain value of the standard die-cast alloy is 5-10%. In order to achieve the maximum strain value at moderate strength values, the EN AC-43500 AlSi10MnMg die-cast alloy was developed. With additional heat treatment, elongation of more than 15% can be obtained, or the yield limit of 260 Mpa can be reached.

    In addition to these special mechanical properties, EN AC-43500 AlSi10MnMg alloy also has the following characteristics in die casting applications: excellent casting performance, no adhesion on die-casting molds, good corrosion resistance, high durability, good welding performance, suitable for punching and pressing.
          With different heat treatment processes (see table below), the mechanical properties of the alloy can be adjusted.

    EMP's engineering team, armed with years of aluminum alloy die-casting process experience, prepared experiments comparing the characteristics of various materials and landed on a technical solution combining EN AC-43500 AlSi10MnMg material with advanced die-casting technology.

    In order to make the castings meet the conditions of heat treatment, the engineers repeatedly tested different die casting methods and determined the vacuum die casting process due to its superior suitability to heat treatment. Castings produced under vacuum die-casting conditions have high compactness and fully meet the conditions of T4-T7 heat treatment.
        After corresponding heat treatment, the elongation rate (A%) of EN AC-43500 AlSi10MnMg can reach 15-20, which is 30-60 times that of general aluminum alloy materials, which meets the requirements for high strength, durable, structural component suitable for lightweight battery pack enclosures for NEV/EV usage.

    Friction welding is a forging welding process. Under the action of pressure, friction occurs between the surfaces of two pipe fittings, generating heat to form a welding line. The relative motion or friction between the two surfaces continues until sufficient heat is generated. After the friction stops, the two parts are forged together with sufficient force to form a welding line.


     friction-welding


    In most applications, the circular or cylindrical parts of pipe fittings are welded and it’s easy for the relative motion to cause friction. There are two different types of friction welding whose difference is the way the energy is transmitted to the system: a continuous drive, or making use of stored inertial energy.


     friction-welding


    Friction welding is not only used for welding plastic products, but also for the welding of different surfaces such as steel - steel, steel - aluminum, copper - aluminum, which are difficult to do with ordinary welding. The speed of friction welding is very fast and each workpiece only takes a few seconds, while ordinary welding takes several times the time.


     friction-welding


    The strength of friction welding is also very large, sometimes even greater than the strength of the material itself, that is, when the external force to pull, the first fracture is not the welding of the material itself rather than the welding point.


     friction-welding


    The application of friction welding is as follows:

    1. bimetallic parts manufacturing

    2. Production of oil drill pipe

    3. Friction welding can realize the composite of various materials and nickel-based super alloy

    4. Friction welding can realize the composite of various materials and copper alloy

    5. Manufacturing construction machinery transmission parts

    6. Production of drill pipe and drill tools

    Porosity is the most common problem of high-pressure aluminum castings. The improvement and elimination of porosity of high-pressure aluminum castings are put forward as follows:


    1. Guarantee the degassing quality of aluminum alloy smelting, the surface and tools of alloy ingot are dry, and the return charge is clean. Select good refining agent, degassing agent, control melting temperature, avoid overheating, reduce the amount of gas in the aluminum liquid, degassing processing. Remove liquid scum, bubble, and other oxides in time to prevent the gas into the high-pressure aluminum casting.


    2. Select a good demolding agent and spraying process, choose a good release agent which doesn't produce gas in the die casting and has good ejection performance.


    high-pressure-aluminum-casting


    3. Make sure that the mold exhaust groove, overflow groove position is correct. The sequence filling is conducive to gas discharge from the cavity, unobstructed exhaust. The smooth exhaust ensures the complete discharge of gas in the mold. Especially in the final convergence of aluminum liquid, the exhaust channel must be clear. The sprue and runner shall be of sufficient length (>50mm) to facilitate the smooth flow of the alloy and the opportunity for gas discharge. It can change the thickness, the direction of the gate, and set overflow groove and exhaust groove at the position where the air hole is formed. The total cross-sectional area of the overflow products shall not be less than 60% of the total of the internal sprue, or the slag discharge effect will be poor.


    high-pressure-aluminum-casting


    4. Select the coating with good performance and control the spraying amount.


    5. Adjust the parameters of high-pressure aluminum casting, especially the injection speed. Have a good command of the casting temperature and keep the filling speed not too fast so as to achieve an orderly and stable flow state and prevent separation and eddy current from forming air entrapment.



    high-pressure-aluminum-casting


    6. Pay attention to core-pulling and cooling to minimize excessive wall thickness differences in product design and mold design.


    7. For the pores that often appear at the fixed position, it is necessary to improve the mold and design, whether there are sharp corners or dead zones, and whether there are changes in the cross-sectional area of the gating system. Computer simulation of the filling process is used to select reasonable technological parameters.

  • Aluminum Aolly is Commonly Used in Auto Engine parts for its lightweight, thermal conductivity and corossion resistance features.

    aluminum-aolly.jpg


    Aluminum alloy is widely known for its lightweight feature, its application in car engine parts can generally reduce the weight of automobile engines by more than 30%. In addition, both the cylinder block and the cylinder head of the engine require good thermal conductivity and corrosion resistance, and aluminum alloys have outstanding advantages over other metal in these aspects.

     

    What is the best engine block material? The aluminum alloy commonly used in die casting engine parts are: American standard A380 / A360 / A356, German standard AlSi9Cu3, AlSi10Mg (Fe), European standard ENAC-43400, ENAC-46400, Japanese standard ADC12, ADC10 etc.

    High-pressure aluminum casting is a kind of widely used parts and components. Because aluminum has stable performance and is durable and hard, which is frequently used in auto parts and some larger structures of industrial machinery and equipment, but sometimes the surface of the high-pressure aluminum casting is oxidized. In this case, oxidized casting is very unstable at work which may lead to breaking down.

    high-pressure-aluminum-casting

    After observation and research, it finds that there are many factors causing surface oxidation of high-pressure aluminum casting. The equipment of high-pressure aluminum casting is not cleaned properly after use, which leads to many material impurities sticking to the surface of the castings and oxidation over time. Or the solution in the casting, which generally contains metal elements, also produces oxidation if kept in the equipment for a long time; In addition, some high-pressure aluminum castings are oxidized due to equipment damage which is caused by improper use during operation.


    high-pressure-aluminum-casting


     In the face of the above oxidation reasons, we need to take corrective measures according to the actual situation and timely clean the casting after use so as to keep the surface free from other impurities and pollution; Improve the casting capacity of the object and adopt appropriate production mode; Clean the metal solution in the equipment in time, fill it with clean water after cleaning, repeat several times and thoroughly clean; For the processing of the production material, remove the impurities contained in the material effectively and appropriately reduce the equipment service time.


    It is a problem widely concerned that the quality of the high-pressure aluminum castings. Some small manufacturers don't strictly control the quality of high-pressure aluminum castings when raising yield at the same time. It is quite easy to cause the failure of mechanical equipment using such defective goods, so you can choose EMP Tech co., LTD. for high-pressure aluminum castings. We have more than 20 years of experience in research and development, manufacturing, and precise processing in the aluminum industry and look forward to cooperating with you.

    Step 1: Analysis and digestion of the 2D and 3D drawings of the product


    die-casting-mold-design


    Step 2: Determine the injection type


    When selecting an injection, the designer mainly considers its plasticization rate, injection volume, clamping force, effective area of the installation mold (distance between the tie rods of the injection machine), modulus, ejection form, and fixed length.


    Step 3: Determine the number of cavities and arrange the cavities


    The number of mold cavities is mainly determined according to the projected area of the product, geometric shape (with or without side core pulling), product accuracy, batch size, and economic benefits.


    die-casting-mold-design


    Step 4: Determine the parting surface


    Generally speaking, the parting surface on the plane is easier to handle, and sometimes you should pay special attention to the parting surface of the three-dimensional form.


    Step 5: Design of the gating system


    The design of the gating system includes the selection of the main runner and the determination of the cross-sectional shape and size of the runner. When designing the gating system, the first step is to select the location of the gate. The proper selection of the gate location will directly affect the quality of the product molding and whether the injection process can proceed smoothly.


    Step 6: Design of the ejector system


    The ejection forms of products can be divided into three categories: mechanical ejection, hydraulic ejection, and pneumatic ejection. Mechanical ejection is the last link in the injection molding process. The quality of ejection will ultimately determine the quality of the product. Therefore, product ejection cannot be ignored.


    Step 7: Design of the cooling system


    die-casting-mold-design


    The design of the cooling system is a relatively tedious task, and the cooling effect, cooling uniformity, and the influence of the cooling system on the overall structure of the mold must be considered.


    Step 8: The guide device on the die-casting injection mold has been determined when the standard mold base is used.


    Under normal circumstances, designers only need to choose according to the specifications of the mold base. However, when precision guiding devices are required to be set according to product requirements, the designer must perform specific designs based on the mold structure.


    Step 9: Selection of mold steel


    The selection of materials for mold forming parts (cavity, core) is mainly determined according to the batch size of the casting and the material of the die casting.


    Step 10: Draw an assembly drawing


    After the ranking mold base and related content are determined, the assembly drawing can be drawn. In the process of drawing the assembly drawing, the selected pouring system, cooling system, core pulling system, ejection system, etc. have been further coordinated and improved to achieve a relatively perfect design in terms of structure.


    Step 11: Drawing the main parts of the mold


    When drawing a cavity or core diagram, it is necessary to pay attention to whether the given molding dimensions, tolerances, and demolding inclination are compatible, and whether the design basis is compatible with the design basis of the product. At the same time, the manufacturability of the cavity and core during processing and the mechanical properties and reliability during use must also be considered.


    Step 12: The exhaust system plays a vital role in ensuring the quality of product molding. The exhaust methods are as follows:


    1. Use the exhaust slot. The exhaust groove is generally located in the last part of the cavity to be filled. The depth of the vent groove varies with different plastics and is basically determined by the maximum clearance allowed when the plastic does not produce flash.


    2. Use the matching clearance of cores, inserts, pushrods, etc., or special exhaust plugs for exhaust.


    3. Sometimes in order to prevent vacuum deformation when the product is ejected, it is necessary to design a vent insert.

    HPDC



    Explanation

    A casting method in which liquid metal is poured into a mold made of metal using the gravity of the earth, and solidify under the action of gravity to form a casting.

    A casting method in which a 660-degree liquid aluminum alloy is poured into the pressure chamber of a die-casting machine to fill a mold cavity under high pressure and high speed, and then come into form under high pressure to obtain a casting part.

    Advantage

    1) There are few pores in the casting, which can be heat-treated, and the strength of the product can be greatly improved after heat treatment.

    2) Long mold life and low mold cost

    3) Higher elongation

    4) The process is relatively simple.

    1) Good product quality

    2) High productivity and more use of die casting molds

    3) Good economic benefits

    Disadvantage

    1) Slow filling and low production efficiency, leading to higher product costs.

    2) Relying on liquid self-weight molding, the product has low density and slightly lower strength.

    3) The surface finish of the product is not high, and the casting product is likely to form a blast-like pit on the surface after cooling and shrinking.

    4) Not suitable for the production of thin-walled parts

    1) The mold structure is complex, the manufacturing cost is high, and the preparation cycle is long.

    2) The die-casting speed is high, the gas in the cavity is difficult to exhaust completely, and the metal mold solidifies quickly in the mold, and the possibility of shrinkage is small, so that the casting is prone to produce small pores and shrinkage.

    3) The plasticity of the die-casting parts is low, so it is not suitable to work under shock load and vibration.

    Application

    Suitable for large wall thickness products, such as steering knuckles, control arms and other chassis safety parts.

    1) Disc, round cover, ring type-pump casing cover, bearing retainer, steering wheel, etc.

    In the process of aluminum castings, if the additives used are not correct, it will affect the degassing and slag removal effect during the casting process, or the casting temperature will be abnormal, which will cause the resulting aluminum castings to have blisters. Defects such as pores and pores affect the normal use of aluminum castings.


    aluminum-casting


    Melting

    In the process of casting a single piece of aluminum casting in an aluminum alloy foundry, if the shape or size of the material is too large, it can be cut into small pieces and then proceed again, which is beneficial to its melting and at the same time it can also have a good casting effect.


    Heat Treatment

    In the as-cast state, its structure and properties are relatively poor, so it is necessary to improve or improve its performance through heat treatment in order to carry out the follow-up process well to avoid some problems. Therefore, it is necessary to make a reasonable selection of the casting method, so as to effectively avoid some casting defects or problems, thereby ensuring the casting effect.


    Application of Aluminum Die Casting

    The aluminum alloy used in aluminum alloy casting is a non-ferrous metal structural material, and its application is very extensive. It has a large number of applications in aerospace, automobile, shipbuilding, machinery manufacturing, and chemical industries, and there are more and more requirements.


    aluminum-casting


    In the casting process of aluminum castings, if the degassing and slag removal is not good, it is mainly due to the two defects of blisters and pores, and this will definitely happen. Therefore, additives can be used for degassing and slag removal, but it is necessary to select the appropriate one and control its dosage to have a good use effect.

    Many customers will ask my product-aluminum die casting parts can be anodized? At present, die casting parts can be anodized, but is difficult. Silicone is an important element that affects the whole anodic oxidation. The content of silicone should not be more that 12%, because silicone is an inert element, while anodic oxidation relies on the chemical reaction between acid and aluminum alloy to generate oxide film on the surface. Cast aluminum alloys and die castings generally contain a high silicon content. The anodized film is dark. It is impossible to obtain a colorless and transparent oxide film. As the silicon content increases, the color of the anodized film changes from light gray to Dark gray to dark gray. it will react chemically with the anodization potion, and the product will be gray-black after anodizing. However, this does not affect its anti-corrosion features. Therefore, cast aluminum alloy can be anodized but is not suitable.


    Also, EMP could provide several suggestions to optimize this issue as below:

    1. Mold runner, gate design, mold temperature control

    2. Use of raw materials to avoid pollution

    3. Process control of die casting process to reduce marks and black watermarks

    4. Pre-processing of rough parts

    Friction welding is one of the welding methods of hot compression welding. The welding efficiency can reach 30~70%. Generally, friction welding with a large dynamic friction coefficient has higher efficiency. Its specific process is as follows:


    friction-welding.jpg


    friction-welding


    1) The contact surface of the two weldments starts to rub. Firstly, the oxides and impurities attached to the surface are destroyed and eliminated. At the same time, the unevenness of the contact surface produces plastic deformation and the crystal grains are destroyed. As a result, the contact surface is heated and reveals a relatively flat and pure metal surface.


    2) Continue to perform frictional motion on the contact surface of pure metal, so that the temperature of the contact surface continues to rise, the plastic deformation increases, and the phenomenon of metal mutual "bonding" (ie, local welding) begins to occur. As the frictional movement continues, the temperature near the contact surface of the weldment rises rapidly and approaches or reaches the welding temperature.


    3) When the welding temperature is reached, the metal has great plasticity. When the relative movement is stopped rapidly and great upsetting pressure is applied, the two weldments will produce great plastic deformation, the metal atoms on the contact surface will be closer, mutual diffusion and intergranular connection will occur, and common recrystallization and intermediate compound will be formed. And a small amount of recrystallized grains to weld the two weldments together.

    The reasons for blackened aluminum die casting parts after shot blasting are:

    1. The dust removal is not done in the equipment during shot blasting;

    2. There are oil stains, mold release and moisture on the casting surface;

    3. Stainless steel pellets are not pure enough.



    To prevent the aluminum die casting parts from blackening after shot blasting, here is some suggestion:

    1. The shot blasting equipment must have a relatively complete automatic dust removal effect;

    2. The surface of the casting should not be contaminated with oil, mold release agent, moisture or other impurities. If necessary, the casting should be washed and dried before shot blasting;

    3. Purchase pure steel shots, if necessary, add 10 ~ 30% aluminum shots to increase the whiteness after shot blasting. The specific amount depends on the requirement of the parts.

    As a highly anticipated processing technology, aluminum alloy die-casting has been expected by more and more people during years of development. How to improve the quality and output value of die casting has also become a key question for manufacturers.


    aluminum-alloy-die-casting


    • Mold Design

    In the aluminum alloy die casting process, the use of excellent quality molds is a useful way to improve the quality and output value of die casting.  As the saying goes, sharpening the ax won't delay the cutting of firewood―good preparation saves work time. The die-casting mold is the "knife" for the production of aluminum alloy castings. The use of high-quality molds will not delay the production of the castings and is more helpful to the improvement of the quality of the castings.


    aluminum-alloy-die-casting


    • Die Casting Technology

    Aluminum alloy die-casting skills are another "knife" for producing aluminum alloy castings. With the continuous improvement of skills and the need for professional development, the aluminum alloy casting profession is also constantly improving, and the die-casting skills are constantly updated. The manufacturers are committed to more perfect die-casting skills and higher-speed die-casting power and continue to improve die-casting skills. The most advanced die-casting skills can always provide aluminum alloy castings of very good quality and higher output value.

    The reason for porosity appeared in aluminum casting parts:

    1.Porosities caused by poor refining degassing quality

    2.Porosities caused by poor exhaust

    3.Porosities due to improper die-casting parameters

    4.Shrinkage hole of aluminum alloy

    5.Porosities caused by excessive wall thickness difference


    Suggestion to prevent the porosities:

    (1)To ensure the quality of refining and degassing of aluminum alloy smelting, choose good refining and deaerator to reduce the gas content in the aluminum liquid, and remove oxides such as liquid scum and bubbles in time to prevent gas from being introduced into the die casting parts.


    (2)Choose a good mold release agent. The selected mold release agent should not generate gas during die casting and have good mold release performance.


    (3)Ensure that the exhaust of the mold is unobstructed, and that the exhaust is smooth, and that the gas in the mold is completely discharged, especially the exhaust channel must be unobstructed at the place where the aluminum liquid is finally polymerized.


    (4)Adjust the parameters of die castings, the filling speed should not be too fast to prevent gas. The casting temperature should also be well controlled.


    (5)Pay attention to the use of core pulling and cooling in product design and mold design to minimize excessive wall thickness difference.


    (6)The air holes that often appear in fixed parts should be improved from the mold and design.

    As the benefits and proportion of motor housing production become increasingly prominent in the manufacturing industry, it is very necessary to understand and master the design and manufacturing process of motor housings.


    motor-housing

    Deep drawing is a processing method in which punched flat blanks are pressed into hollow pieces with various openings or the finished hollow pieces with openings are processed into hollow pieces of other shapes.


    The force process of the motor housing deepening is similar to the change of the fan-shaped blank being pulled through a wedge-shaped slot. While being elongated in the diameter direction, the tangential direction is compressed. In the actual drawing process, of course, there are no wedge-shaped grooves, and the fan-shaped small unit bodies on the blank do not exist alone but are in an interconnected and tightly integrated whole blank.


    motor-housing


    The thickness of the workpiece obtained after the deep drawing is different from the bottom to the mouth.


    The thickness of the upper part of the sidewall of the cylinder increases the most, about 30%; the thickness of the sheet is the smallest at the corner of the cylinder wall and the bottom, and the thickness is reduced by nearly 10%, where it is most likely to be broken during deep drawing. When the stress of the section exceeds the strength limit of the material at this time, the part will crack here. Even if the drawn part is not cracked, the product may be scrapped due to excessive thinning of the material.


    motor-housing



    At present, a large-area motor casing is being processed.


    The original process is to align the shape of one end to straighten the middle, position the hole, and process the end to form the motor casing through the four-jaw clamp for vertical vehicles. When this method is not easy to operate and the vertical processing is not accurate, the production efficiency is low. How to shorten its production cycle, improve labor productivity, and reduce its production cost under the premise of ensuring the quality of parts processing is particularly important.

    Die-casting machines are generally divided into hot-cast chamber die-casting machines and cold-pressure chamber die-casting machines. Cold-die chamber die-casting machines are divided into bedroom die-casting machines and vertical die-casting machines according to the structure and arrangement of their pressure chambers.


    Hot chamber die casting machine has a high degree of automation, less material loss, and high production efficiency. However, during the hot die casting process, due to the heat resistance of the machine parts, it can only be used for the production of zinc alloy, magnesium alloy, and other low melting point castings.


    The pressure chamber of the hot-press chamber die-casting machine is immersed in the liquid metal of the heat-preserving melting crucible. The injection parts are not directly connected to the machine base but are installed on the crucible. The advantages of this die-casting machine are the simple production process, high efficiency, low metal consumption, and stable process. However, the pressure chamber and injection punch are immersed in liquid metal for a long time, which affects the service life and easily increases the iron content of the alloy. Hot-press chamber die-casting machines are currently mostly used for die-casting low-melting alloy castings such as zinc alloys, but also for die-casting small aluminum and magnesium alloy die castings. Due to the high melting point of aluminum alloy die castings widely used today, most castings can only be produced on cold chamber die casting machines.


    The cold chamber die casting machine is to pour the molten metal liquid into the injection chamber (into the barrel) through the soup spoon, and then use the injection piston (hammer) to push the metal liquid into the mold at high speed, while maintaining a certain pressure In the case of cooling and solidification to obtain casting equipment. The cold chamber die casting machine is suitable for die casting of various non-ferrous metals and ferrous metals. The production operations are few and simple, the production efficiency is high, and it is easy to realize automation.

    The development of the aluminum alloy die-casting industry is not very smooth. In the process of its development, there will always be various factors that hinder its development. Let's take a look at what affects the development of the aluminum alloy die-casting industry.


    1. Aluminum production factors


    When it comes to the factors affecting the forward development of the aluminum alloy die-casting industry, the first thing that should be mentioned in the output of aluminum.


    aluminum-alloy-die-castingaluminum-alloy-die-castingaluminum-alloy-die-castingaluminum-alloy-die-casting

    Aluminum is the main raw material used in die casting. The global output of this metal has been declining in recent years, and the lack of raw materials has greatly restricted the development of this industry. The emergence of this situation cannot be solved by manpower, but we still need to actively solve it.


    2. Processing technology factors


    One of the solutions is the continuous improvement of processing technology, which is also the second factor affecting the development of the die-casting industry. If the companies in the industry can unite to carry out technical research and development and improvement, not only can the production efficiency be improved, but also the utilization rate of this kind of raw materials can be improved. This is also a mitigation measure for the lack of aluminum. It is worthy of priority consideration by enterprises in the industry.


    aluminum-alloy-die-casting


    aluminum-alloy-die-casting


    Based on the above influencing factors, the improvement of technology and the utilization of raw materials have a great influence on the development of the aluminum alloy die casting industry.


    Nowadays, with the advancement of science and technology, many industries have integrated computer control and filling technology in their production equipment, especially in the aluminum alloy die casting industry, this phenomenon is particularly obvious.


    Such a change, on the one hand, shortened the production cycle and greatly improved the efficiency of production. On the other hand, it also improved the quality of castings and started the brand war. The development of aluminum alloy die-casting equipment on the trend of automation is still at a basic stage. I believe that with our joint efforts, this technology can achieve greater progress.

    1. The heat dissipation of aluminum alloy is so good. It is much higher than radiators of other materials, so the heat dissipation capacity of aluminum alloy radiators is much higher than that of other materials.


    2. The chemical activity of aluminum in the alloy is very active, and it is easy to react quickly with oxygen in the air to form a dense aluminum oxide protective film whose thickness is about 1μm. Its combination with the substrate is very strong, which makes the surface of the coating passivated and prevents its own oxidation continuously. Therefore, the aluminum alloy itself is not afraid of oxygen, and there is no oxygen corrosion. The principle of the internal anti-corrosion of the radiator: the internal anti-corrosion treatment of the radiator is to coat a layer of organic paint with good adhesion and corrosion resistance on the inner surface of the radiator to isolate the water,  steel and aluminum material to antiseptic effect. The aluminum alloy has a dense aluminum oxide protective film on the surface, so it is difficult to adhere to the anti-corrosion coating. Even if it is applied, the anti-corrosion coating block on the surface layer of the aluminum alloy is easily peeled off under the scouring of the water inside the radiator.


    3. Aluminum alloy radiators, with their superior corrosion resistance, wide applicability, better heat-to-price ratio, higher value retention rate and beautiful appearance, will become the leading players in new radiators for a long time to come. The market prospect is also very broad. With the continuous development and promotion of aluminum alloy radiators, it will play a greater role in the development of the industry.

    Within the controllable range of the drying process, carry out 4h, 5h, 1h drying time tracking experiments for each layer of aluminum castings that are prone to surface burrs, quick-plug joints, etc. The data shows that the burrs of the aluminum castings dried for 4h continue to rise, while the castings dried for 6h and 12h are free of burrs. It can be seen that the drying time is too short and the mold shell is not dried deeply, which are the key elements that harm mold shell cracks and surface burrs of aluminum castings. Therefore, the drying time should be 8 to 10 hours.


    aluminum-casting


    According to the left and right processing technology, the wide range of actual results is good, but there are still cold barriers for the position of the outer bevel of some thick-walled aluminum castings and some. Therefore, first, raise the temperature to 950°C during the firing of the shell, then heat insulation, and then raise the temperature to 1050~1150°C within 5~7min before pouring, which can eliminate the shortcomings of cold insulation.


    aluminum-casting


    From the test, it is better to have a higher working pressure for dewaxing, but after measuring the increased rate of working pressure at 0.85MPa, 0.75MPa, and 0.65MPa, the working pressure can exceed 0.48-0.56MPa in the first 10s under these three working pressures. The higher the working pressure, the faster the increase rate, and the increase rate slows down significantly after 1 min. Therefore, generally in the production of aluminum castings, people manipulate the working pressure increase rate to exceed 0.48 MPa in the first 10s.


    It can be seen that in the production process of aluminum castings, the control of pressure and drying time is very important.


    aluminum-casting

    1. Adjust die casting process parameters

    The setting of process parameters has a great influence on the sticky mold, such as the size of pressure and speed, the pouring temperature of the alloy, the temperature of the mold, etc., so the reasonable process parameters should be calculated according to the structure and use requirements of the casting.



    2. Improve the design structure of the gating system

    The design structure of the improved gating system is to prevent the alloy liquid from continuously washing the cavity wall or core, and to appropriately increase the cross-sectional area of the inner gate. Change the position of the gate and the direction of introduction, so that the introduction is in a wide and thick position, and try to adopt the open pouring system of the bottom injection method. Sticking at the intersection: Start to improve the mold runner. The high gate speed makes the temperature of the local mold of the metal impact wall rise, and the formation of the sticky mold is faster, so you need to consider reducing the gate speed.



    3. Temperature control of aluminum alloy mold

    The higher the mold temperature, the easier it is to produce sticky molds. In the actual production process, we can use infrared thermometers to detect the mold sticking parts, control the mold temperature between 150 ℃ ~ 220 ℃, so that the mold reaches thermal equilibrium. The casting temperature of aluminum alloy is set to the minimum according to the requirements of castings, between 610 ℃ ~ 680 ℃, to reduce the formation of sticky mold.



    4. Mold surface treatment

    Some surface treatment methods can prevent the occurrence of sticky molds. Special materials with higher melting points should be used to treat the surface of the mold. Various materials to prevent the occurrence of sticky molds can also be used to treat the surface of the mold to improve the surface of the mold. The hardness of the material at high temperature, the method of reducing the activity of the mold surface to avoid sticking the mold and other ways.



    5. Adjust the spraying position and spraying amount; check the hardness value of the mold, adopt heat treatment and nitridation or replace the mold material; reduce the injection speed appropriately; increase the mold cooling, increase the spraying on the overheated position, and apply the Install a cooling system, etc.

    Aluminum castings need to be preheated before use. The aluminum mold must be preheated to a certain temperature before use. Preheating can prolong the service life of the mold. Generally, electrical appliances or induction heating are used for preheating. The preheating temperature is controlled at 250℃~300℃. It can be used after heat preservation for about 0.5h. It is forbidden to use molten metal to directly preheat the mold, because the cold mold is in direct contact with the hot liquid metal, and it is bound to be subjected to thermal shock, which will cause thermal erosion and accelerate the cracking and peeling caused by thermal fatigue.


    aluminum-casting1


    In the process of making aluminum castings, it can effectively improve the quality of the surface processing of the mold cavity. The surface of the mold cavity should not have obvious deep processing tool marks to prevent the mold from cracking due to stress concentration during mold finishing. The surface of the cavity should be effectively polished and ground so that the surface roughness of the cavity should be controlled below 0.8μm.


    aluminum-casting



    In continuous production, the temperature of the aluminum casting mold tends to rise. Excessive temperature not only causes the liquid metal to produce boulders but also slows down the cooling of the castings, resulting in coarse crystal grains and lower quality of the aluminum castings. Therefore, when the temperature of the cast aluminum mold is too high, cooling measures should be taken. Compressed air or water is usually used for cooling. Cast aluminum molds are generally designed with a cooling system to ensure the thermal balance of the mold.


     aluminum-casting


    After the cast aluminum mold is used, to a certain extent, the mold cavity should be cleaned in time to effectively remove the residual aluminum. After cooling, it should be anti-rust treated, and placed in the warehouse, and placed under centralized management for reuse. At the same time, by grasping the relevant links of mold design, manufacturing, use, maintenance, and management, the service life of cast aluminum molds can be effectively extended, and the cost of motor manufacturing can be reduced accordingly.

      Aluminum alloy die castings have many advantages than other castings, such as good surface, lightweight, corrosion resistance, etc., especially in automobile lightweight, aluminum alloy castings have been widely used in the automotive industry.


       1. Advantages of Aluminum Alloy 

      Aluminum castings are less dense than cast iron and cast steel, and stronger than the latter. Therefore, the use of aluminum alloy castings under the same load conditions can reduce the weight of the structure, so aluminum alloy castings are widely used in the aviation industry and the manufacture of power machinery and transportation machinery. Aluminum alloy has good surface gloss and good corrosion resistance in the atmosphere and freshwater, so it has a wide range of uses in the manufacture of civilian utensils. Pure aluminum has good corrosion resistance in oxidizing acid media such as nitric acid and acetic acid, so aluminum castings also have certain uses in the chemical industry. Pure aluminum and aluminum alloys have good thermal conductivity and are placed in heat exchange devices used in chemical production, as well as parts requiring good thermal conductivity on power machinery, such as cylinder heads and pistons of internal combustion engines.


       2. Performance of Aluminum Die Casting

      Aluminum alloy die castings have good casting properties. Due to the low melting point (the melting point of pure aluminum is 660.230C, the casting temperature of aluminum alloy is generally about 730 ~ 750 ℃), it can be widely used casting methods such as metal mold and pressure casting to improve the intrinsic quality of castings, dimensional accuracy and Surface finish and production efficiency. Due to the large latent heat of solidification of aluminum alloys, under the same weight conditions, the solidification process of aluminum liquid lasts much longer than that of cast steel and cast iron, and it has good fluidity, which is easy for casting thin-walled and complex-structure castings.

    Alloy aluminum castings have many advantages, making it one of the more popular casting products for the development direction of the casting industry and purchasing customers. In the future, with the progress of aluminum alloy casting technology, it will show its own style on a larger stage.

    2. Alkaline electrolytic polishing process of aluminum:

    The research of alkaline polishing solution system was carried out, and the influence of corrosion inhibitor, viscosity agent, etc. on the polishing effect was compared, and the alkaline solution system with the good polishing effect of zinc-aluminum die casting was successfully obtained, and for the first time, it was obtained that the operating temperature can be reduced. , Additives that prolong the service life of the solution while improving the polishing effect. Polished under this process condition, the surface reflectivity of aluminum after leveling can reach about 87%, and its operating temperature, solution service life, and aluminum loss during polishing are far superior to the reported alkaline DC electrolytic polishing. The surface reflectivity of aluminum can reach 90%, but due to the unstable factors in the experiment, further research is needed.

    electroplating1.jpg

    3. Environmentally friendly chemical polishing of aluminum and aluminum alloy:

    Electrolytic polishing refers to the finishing process in which metal products undergo special anodic treatment in a solution of a certain composition to obtain a smooth and bright surface. It can be used to prepare the surface of the product before electroplating, and also be used to finish the surface after planting, and it can also be used as an independent finishing processing method for the metal surface. A smooth and flat surface can be obtained by chemical polishing, which enhances the light reflection ability, heat reflection ability, and corrosion resistance of aluminum, and improves the decorative effect of aluminum products.

    4. Electrochemical surface strengthening treatment of aluminum and its alloys:

    The process, properties, morphology, composition, and structure of the ceramic-like amorphous composite conversion coating formed by anodic oxidation and deposition of aluminum and its alloys in a neutral system and the film formation process and mechanism of the coating were discussed. Process research results show that, in the Na_2WO_4 neutral mixing system, the concentration of film-forming accelerator is controlled to be 2.5-3.0g/l, the concentration of complexing film agent is 1.5-3.0g/l, and the concentration of Na_2WO_4 is 0.5-0.8g/l, The peak current density is 6-12A/dm~2, and weak agitation can obtain a complete, uniform, and good-gloss gray inorganic non-metallic film. The film has a thickness of 5-10μm, a microhardness of 300-540HV, and excellent corrosion resistance. The neutral system has good adaptability to aluminum alloys and can form a good film on various series of aluminum alloys such as rust-proof aluminum and forged aluminum.

    The design process of die-casting molds is very similar to the design process of plastic molds, and both feed methods and mold structure layouts need to be considered. However, the design of the die-casting mold should also consider the following key points: the position distribution and distribution between multiple feed gates; the calculation of the cross-sectional area of the feed gates, the calculation of the cross-sectional area of the runners at all levels; the location of the slag ladle, whether the exhaust slot is reasonable; It is also necessary to consider how to drain the front and discharge the residual liquid of the spray release agent; prevent the accumulation of the front and the waste residue, and so on. How to improve and optimize die casting mold technology?


    1. Use "die-casting mold flow analysis software" to assist in the analysis and selection of mold design schemes


    die-casting-mold



    Every new set of die casting molds may hide unknown potential problems. If you only rely on personal experience and technology to design die-casting molds, there will be certain differences due to personal experience and technical level. It is difficult to ensure that each set of die casting mold design reaches the best rationalization, and it is difficult to effectively improve the quality of mold design. Therefore, it is necessary to use auxiliary software to realize the innovation and development of die casting mold design. The die-casting mold flow analysis software can verify the plan when the mold design plan is completed and the 3D parting is completed.


    2. Slag discharge and exhaust structure


    die-casting-mold


    During die-casting, the temperature of the metal broth flowing at the forefront will decrease, and condensate is prone to appear, which will also affect the appearance and internal quality of the casting (product). Therefore, whether the design of the slag discharge and exhaust structure of the die-casting mold is reasonable determines the quality of the entire casting (product) to a large extent. In order to break the traditional design thinking, in addition to considering the installation of slag discharge and exhaust at the end of the casting flow and the places where cold material is easy to be placed; innovative design and innovation application of the slag ladle gate, slag ladle, and exhaust trough should also be considered.


    3. The structure of the slag discharge groove of the slider mechanism


    die-casting-mold


    During the production of die-casting molds, a large amount of metal scraps, that is, piping is produced. In particular, once the slider mechanism is blocked and obstructed by the front, it will not be able to move normally or even get stuck, causing the whole set of molds to fail to produce normally.


    In addition to lubricating oil grooves at the bottom of the slider seat, some slag discharge groove structures must be designed, which can effectively accommodate and store the flares falling under the slider seat during a long period of production time; Until the mold completes the production task, the front and sundries will be thoroughly removed to ensure the smooth operation of the slider and good production efficiency.

    Ⅰ. Aluminum die casting molds are attracting more and more attention


    With the rapid development of die-casting technology, the die-casting industry has received corresponding attention. The diversified development of aluminum alloy die-casting has promoted the rapid application of the die-casting industry, especially the application of aluminum die-casting molds.



    Ⅱ. The surface treatment requirements of aluminum alloy die casting molds


    In the practical application of aluminum alloy die casting molds, people often do not understand the surface quality of aluminum die casting molds and its requirements. Let's take a quick look.



    1. If there are no special regulations on the drawing, the settings of the die casting process, such as the position of the ejector pin, the position of the parting line, the position of the gate and the overflow, etc., shall be specified by the manufacturer. Otherwise, the settings should be indicated on the drawing or agreed upon by the supplier and the buyer


    2. The surface of aluminum die casting mold that needs special processing, such as polishing, shot peening, chrome plating, coating, anodizing, chemical oxidation, etc., shall be indicated on the drawing or agreed by the supplier and the buyer.


    3. Aluminum die casting molds are allowed to have defects such as scratches, dents, lack of flesh and net burrs. However, the degree and number of defects should be consistent with the agreed standards of the supply and demand parties.


    4. The gate, flash, overflow, septum, and ejector pin traces of aluminum die casting molds should be cleaned up. But it is allowed to leave traces.


    5. The casting mold is not allowed to have cracks, under-casting, looseness, bubbles and any penetrating defects.

    1. The lightweight of EV Battery Housing


      In addition to the lightweight of the body structure, the battery pack itself also needs to be lightweight. The lightweight of the battery housing is one of the directions of efforts.

    Especially for battery packs of pure electric vehicles, the pursuit of high mileage on the premise of the current lithium-ion battery level of development will inevitably require that the weight of the battery case be reduced as much as possible while ensuring high structural strength, the weight of the battery pack can be reduced about 10-30% by using light aluminum alloy than by using steel, which can reduce the overall weight of the battery pack to some extent.

      Die-casting and extrusion are commonly used in the production of aluminum alloy housing. The housing can be molded in one piece (flatness and accuracy are affected to a certain extent, especially if the installation interface has sealing requirements, it may require post-processing to modify), do not need welding, need large tonnage die-casting machine to achieve, generally subject to size restrictions, housing size will not be too large, usually used for battery tray, you can increase the tailor-welded process to compensate if the size of housing is too large.



    2. Examples of battery housing made of Die-cast Aluminum Alloy


      1) GM Cadillacs battery housing using stamping and high-pressure casting process (below) , the tray using aluminum high-pressure casting (HPDC).


      2) This battery housing is made of aluminum high pressure die casting aluminum Alloy AlSi10MnMg with a weight of 6.4 kg.



      3) The parts as below show low pressure die casting of Aluminum Alloy AlSi7Mg with integrated cooling function.



      In general, the application of die-casting aluminum alloy in battery housing can be low-pressure casting or high pressure die casting. According to different requirements, it can also integrate the cooling function in it, omitting the individual cooling plate, which may be one of the trends in the future.

    1. Aluminum alloy die casting


    Aluminum alloy die castings can be seen everywhere in daily life, but in the production process of die cast aluminium alloys, various problems will occur. Casting deformation is one of the most important problems, why would this happen? And how should we solve this problem?


    2. Reasons for deformation of aluminum alloy die castings


    There are two characteristics of the deformation of aluminum alloy die castings: one is the overall or partial deformation, and the other is that the geometry of the die casting does not match the drawing. Reasons for this situation are: poor casting structure; premature opening of the mold, resulting in insufficient rigidity of the casting; improper setting of the ejector rod, resulting in uneven force during ejection; improper gate position or thick gate made it easy to deform when removing the gate; the rough surface of the mold causes high resistance and the product deforms when ejected; the mold temperature is too high, resulting in the casting is not fully solidified, or the ejection force is too large, causing the product deformation.


    For the problem of deformation of aluminum alloy die castings, the solution is to "apply medicine according to indications", such as improving the structure of the casting; adjusting the mold opening and holding pressure reasonably; setting the ejection position and the number of ejectors rationally; changing the gate position to reduce the gate thickness ; strengthening the mold surface treatment to reduce the demolding resistance; controlling the local mold temperature to maintain the thermal balance of the mold.

    In the aluminum alloy die-casting production process, temperature is one of the core process elements. The quality of die-casting mold temperature control directly affects product quality and production efficiency. The choice of die-casting mold temperature control method is particularly important.


    die-casting-mold


    During the die-casting production process, the heat absorbed by the mold must be the same as the heat discharged, to prevent the die casting mold from getting colder or hotter, and to reduce casting defects such as shrinkage holes and pores caused by uneven mold temperature. Improve the appearance and internal quality of castings, the service life of molds, and production efficiency. Reaching the thermal balance is the process of cooling the mold at a high temperature and heating it at a low temperature.


    die-casting-mold


    Mold temperature is one of the very important process parameters. It not only determines the quality of castings but also seriously affects the service life and production efficiency of the mold. Therefore, to the die-casting production process and the different conditions of the die-casting mold. With the development of die-casting technology, new temperature control methods are constantly being updated. The application of new methods will further improve the level of mold temperature control and contribute to the production of faster and better die-casting parts.

      High-quality products are manufactured, managed, and controlled, not tested. Quality control is a systematic project, with its own rules and unique control methods; if you do not master the correct quality control methods, it is difficult to control the quality of the product, and even some unexpected quality problems may occur, causing great business Economic losses.


    1. Don't easily determine the process, do not easily change the determined process

    1) If the product has quality problems, the root cause, main factors or main performance of the problem should be found;

    2) Before you understand the problem, easily changing the process actually masks the real cause and problem.


    2. Process control must have a strong sense of quantification and traceability

    1) Quality depends on many factors, do not ignore any details;

    2) Any details should be controlled and recorded with data as much as possible;

    3) Failure to control and trace the process details will mislead corrections and preventive measures.


    3. Be patient when solving problems

    1) Don't ignore the abnormal situation because it doesn't seem to be related to the problem solved;

    2) Standardize the analysis of the influencing factors when you couldn’t find the reason and regular pattern

    3) Review some experiences and regular pattern of previous experiments and sum up;

      aluminum-CMM-inspection.png

    4. To build prevention thinking

    1) The highest level of quality management is prevention, not how to save after a problem;

    2) When the same quality problem is repeated for the second time, it should be highly valued;

    3) The daily process and result data should be sorted with certain tools, and the regularity and change trend should be looked for from the sorted results. These regularities and displayed trends need to be revised continuously;


    5. Quality control must have management thinking

    1) Do not want to rely directly on the technician to achieve product quality stability;

    2) The quality of the product is manufactured, without direct management of the manufacturer, the quality can never be stable;

    3) To observe, pay attention to and study the performance and status of the direct manufacturer of the product, and manage and mobilize these performances and status


    6. Listen for more opinions and suggestions

    1) Don't assume that if others don't know what's really going on and can't solve the problem at once, opinions are of no value;

    2) But they, especially the direct product manufacturers, can give us many tips and reminders;

    3) The thinking of quality management often touches the forefront of technology. Even a casual sentence or a complaint may guide or imply a major technical innovation direction. Therefore, a professional technician should be a person who pays attention to detail and is good at capturing it.

    1. The advantages of aluminum alloy die castings


    Aluminum alloy die castings have the advantages of high production efficiency, low processing costs, easy mechanical automation in the production process, high dimensional accuracy of the castings, good surface quality, and good overall mechanical properties.


    2. The forming principle of aluminum alloy die casting


    Aluminum alloy die castings must be formed by molds and combined with die-casting machines and aluminum alloys for comprehensive use. The principle of pressure die casting process is that the metal liquid is poured into the cavity of a precision metal mold at high speed under high pressure, and then the metal liquid is cooled and solidified into a casting under pressure. Cold and hot chamber die castings are two basic ways of die-casting process. In cold chamber die-casting, metal liquid is poured into the chamber by manual or automatic casting device, then the injection punch moves forward and presses the liquid metal into the cavity. In the hot chamber die casting process, the pressure chamber is perpendicular to the crucible, and the molten metal flows into the pressure chamber automatically through the feed port on the chamber. The injection punch moves downward to push the molten metal into the cavity through the gooseneck tube. After the molten metal is solidified, the die-casting mold is opened and the casting is taken out to complete the entire die-casting forming process.


    In the process of making aluminum alloy die castings, the surface processing quality of the mold cavity can be effectively improved. And the surface of the mold cavity should not have obvious deep machining marks to prevent the mold from cracking due to stress concentration during work. When the mold is finished, the surface of the cavity should be effectively polished and ground to keep the surface roughness of the cavity under 0.8μm.

    Ⅰ. The importance of aluminum alloy die casting design


    In the casting and molding process of aluminum alloy die castings, defects such as pores, flow marks, scratches, dents, cracks, under-casting, etc. are easy to occur. These defects deteriorate the appearance quality and mechanical properties of die castings. In order to avoid the above problems in the die-casting molding process, structural designers need to evaluate the plan in advance during the structural design of die-casting parts, and rationally layout the parts in the structural design, and reduce the defects to a minimum by optimizing the structure.


    Ⅱ. The design points of aluminum alloy die castings


    The design rationality of aluminum alloy die casting is related to the entire die-casting molding process. Therefore, when designing die castings, the design, the structural characteristics and the process requirements should be fully considered, so as to reduce the defects of the designed die castings in the process of die-casting forming and improve its quality to the greatest extent by the optimal design scheme.


    1. Reasonable design of die casting wall thickness


    In the structural design of aluminum alloy die castings, the wall thickness must be fully considered. Wall thickness is a factor of special significance in the die casting process. If the design wall thickness is too thick, there will be external surface defects such as shrinkage hole, sand hole, porosity and coarse internal grain, which will decrease the mechanical performance and increase the quality of parts, leading to the increase of cost. If the design wall thickness is too thin, it will cause poor filling of liquid aluminum and formation, so that the aluminum alloy is not well-dissolved, and defects such as difficulty in filling the surface of the casting and lack of material are prone to occur, bringing difficulties to the die casting process.


    2. Reasonable design of reinforcement ribs for die castings


    Large-plane or thin-walled die castings have poor strength and rigidity, and they are easy to deform. However, the use of stiffeners can effectively prevent the die-casting from shrinking and breaking, eliminate deformation, and enhance the strength and rigidity of the die-casting. For over-high column, platform and other structures, the reinforcement can be used to improve the stress distribution and prevent root fracture. At the same time, the reinforcement can assist the flow of molten metal and improve the filling performance of castings.


    3. Reasonable design of the angle of die casting


    The the aluminum alloy die-casting inclination is to reduce the friction between the casting and the mold cavity and to take out the casting easily. In general, the exiting inclination of the outer surface of the die casting is about 1/2 of the exiting inclination of the inner cavity, but in the actual design, the exiting inclination of the inner and outer surface of the die casting can be designed as the same, so as to maintain uniform wall thickness and simplify the structural design.


    4. Reasonable design of machining allowance


    Machining should be avoided in the design of die casting for it will destroy the dense layer on the surface of parts and affect the mechanical properties of them. Machining will also expose the internal pores of the die casting, affect the surface quality, and increase the cost of the parts. When machining of die-casting parts cannot be avoided, the design with larger cutting volume should be avoided as much as possible, and the structure design should be as easy as possible for machining or reducing the machining area and the machining cost.


    5. Spray design of aluminum alloy die castings


    The surface spraying design of aluminum alloy die castings generally adopts the powder spraying process. The principle is electrostatic powder spraying: the paint is mainly polarized by electrodes, and then the object to be sprayed is charged with opposite charges, and the powder is uniformly attached to the surface of the object under the action of the electric field. The characteristics of powder spraying process: powder electrostatic spraying will not cause air pollution; powder can be recycled to reduce material consumption costs, and the coating film has good acid, alkali and corrosion resistance.

    I. The continuous development of die cast tooling

     

    According to the quantity, size and shape of aluminum castings, aluminum casting manufacturers choose different materials to make die-cast tooling. Usually, aluminum casting manufacturers also choose wood, bakelite, aluminum alloy, hot mold steel and other materials referring to the number of aluminum casting parts (that is, the use frequency of die casting tooling). At present, wood die-cast tooling is still widely used in manual modeling of alloy casting process or unit production, but with the increasingly stringent environmental protection requirements, the use of wood will be increasingly limited, and the solid die-casting of aluminum alloy will take the place of it.

     

    II. The different types of die cast tooling

     

    1. Aluminum die cast tooling

     

    Aluminum tooling refers to the die-cast tooling that uses aluminum as the raw material. Compared with wood tooling, aluminum tooling not only saves wood, but also makes the casting have higher dimensional accuracy and better surface roughness. The application of aluminum alloy die cast tooling has been on the rise in recent years.

     

    2. Steel die cast tooling

     

    It is also known as metal die-cast tooling. With the hot die steel as the die material, the shape of the workpiece is directly processed on the die steel. The liquid aluminum is directly poured into the steel die in the casting process. It is very suitable for the production of large quantities of aluminum castings, which have the advantages of high strength, high hardness, wear resistance, good processability, low cost, long service life and so on.

     

    With the rapid development of industry, the processing technology of die-cast tooling has been continuously improved, and the level of aluminum alloy casting has also been improved. More and more new casting dies and processes have emerged and developed.

    I. The advantages of aluminum electric motor housing


    In the field of electric vehicles, it has higher technical requirements on the casting process when the aluminum alloy is used for electric motor housings. It needs to be light, rugged, durable and economically viable. EMP Tech Co., Ltd. has studied the casting aluminum alloy material and the corresponding manufacturing process for the electric motor housings of hybrid and pure electric vehicles.


    II. The development of casting aluminum electric motor housing


    1. The integrated design of drive motor


    In the context of increasingly strict requirements for CO2 emissions and fuel consumption, the development of new energy vehicles has also promoted the development of drivers. From hybrid vehicles to plug-in hybrid vehicles to pure electric vehicles, drive motors have developed multiple types of products at every stage. Early hybrid vehicles were modified from petrol-powered vehicles, and their drive motors have multiple components and low integration. With the development of motor technology, drive motors with simple structure, fewer components and high integration are favored.


    Integrated design solutions have manufacturing advantages because they reduce manufacturing costs by eliminating critical interfaces. They can also achieve weight loss and performance improvements. The cooling channel of the motor can be formed directly during casting, which has a larger space for design and optimization. Because of the complex casting structure, the casting process of aluminum electric motor housing mostly adopts CPS or gravity casting.


    2. The design of cooling channel


    The design of the aluminum electric motor housing and cooling channel is critical to the operation of the motor drive, while optimizing the channel design can also improve the cost-effectiveness. The design and optimization are usually realized through simulation analysis.


    The complex geometry (serpentine or spiral) of the cooling channel presents challenges in the production of the housing for integrated electronic equipment. With the help of fluid dynamics (CFD) calculation, the best scheme is studied. CFD simulation has the advantage of shortening the development time.

    I. The importance of aluminum castings


    With the improvement of aluminum alloy casting technology, most of the aluminum castings are metal mold castings and shell mold precision castings. The workpiece surface obtained by the two kinds of castings is finer, and the internal structure is more exquisite. But sometimes the workpiece blackening phenomenon will appear in the process of use. How is this blackening phenomenon formed? Here are exclusive explanations of the reasons for aluminum casting blackening.


    II. Reasons for surface blackening of aluminum castings


    1. The influence of storage environment. If aluminum castings are stored in humid places for a long time, mold grows, which leads to blackening.


    2. The machined foundry aluminum casting can not be cleaned thoroughly without cleaning treatment or simply with water, which leads to the residual cutting fluid, saponification fluid and other corrosive substances on the surface and speeds up the blackening.


    3. The blackening phenomenon caused by the use of environment. Corrosive gas or chemicals in the working environment of aluminum castings will result in corrosion.


    The above three points are the main reasons for the blackening of aluminum castings in the later stage. We hope users can pay attention to them.


    EMP Tech Co.,Ltd. has experienced engineering, technical management and quality assurance teams, and we are ready to support the most challenging projects. We have provided our customers with precision machining prototypes, mold designs, extensive product testings and mass production assistance.

    I. A brief introduction of shot blasting aluminum castings

     

    Generally, the last process of the aluminum casting blanks produced in aluminum casting plants is shot blasting, so what are the differences between shot blasting aluminum castings and ordinary aluminum castings? Here is an exclusive explanation for you.

     

     

    II. The differences between shot blasting aluminum castings and ordinary aluminum castings

     

    1. The surface of the shot blasting aluminum castings can present the natural color of the matrix.

     

    After shot blasting treatment, the surface attachments, thin edges, wings, spots and scratches can be removed, so that the workpiece presents the original color of the matrix.

     

    2. Eliminate stress concentration on the surface of ordinary aluminum castings.

     

    During the cooling process of aluminum castings, the uneven wall thickness and the inconsistent cooling rate lead to the stress concentration on the surface. After shot blasting cleaning, the surface structure of the shot blasting aluminum castings can be improved, the surface stress (tensile stress) concentration can be eliminated, the fatigue strength can be strengthened, and the surface hardness can be slightly increased.

     

    3. The surface of shot blasting aluminum castings is more aesthetic.

     

    Because the projectile is spherical, the projectile produces small, concave, and spherical holes on the aluminum castings, which makes the surface just like a concave mirror. Under the light, it shines like stars, which is pleasing to the eye.

     

    4. The surface spraying adhesion of shot blasting aluminum castings is significantly improved.

     

    After shot blasting cleaning, the roughness of the shot blasting aluminum castings can reach Ra1.6 ~ 6.3 μm, and the surface area is greatly increased. At the same time, the surface dirt is eliminated. Therefore, when the surface is sprayed or painted with other coatings, its adhesion is greatly enhanced.

    I. Introduction of aluminum casting heat treatment


    Heat treatment is an indispensable process for aluminum castings to achieve the best mechanical properties. In addition, heat treatment has other functions:


    A. Make each part of the casting structure uniform and the same.


    B. Eliminate internal stress caused by solidification shrinkage.


    C. Make the size stable and not change nay more.


    D. Increase the workability of the material.


    F. Increase the corrosion resistance of the material.


    The purpose of aluminium casting parts heat treatment is to produce a wide range of usable hardened elements, such as copper, magnesium, zinc, or polydissolved solids. A more homogeneous solid solution can be obtained by keeping the aluminum casting at a high temperature of 535 °C to 550 °C for 6-8 hours.



    II. The solid solution temperature of aluminum castings


    The solid solution point of aluminium casting is 530 degrees, and the melting point is 555 degrees, beyond which the aluminum castings will be molten into aluminum water.


    III. Process points of aluminum casting heat treatment


    A. When heating up, open the cooling water of the windmill smoothly first, and then set the operating temperature of the windmill in full swing. Combustion status: When entering the furnace, the casting should be placed with A-side up, and A-side down is prohibited (in solution treatment).


    B. The temperature of the solution and aging treatment shall be stable and uniform, which shall be determined by the design strength, material, characteristics and test of the wheel ring.


    C. The quenching water temperature is 60 degrees-80 degrees, so that the aluminum casting is not easy to deform. The quenching time is calculated from the entry of the casting until the top casting is fully immersed in water. It is best to finish the instant quenching in 16-20 seconds.


    D. Fully inspect the items after solid solution treatment, including deformation inspection, shaping, steel word prevention and quality anomaly tracking. After aging, the upper and lower layer of each car respectively measures the hardness of an aluminum casting, and the value is 65-75 HB. Cooperate with continuous automatic operation, send the casting into the furnace after pre-furnace, which is the same as high-temperature operation. Enter and leave the furnace for operation according to the time set by the timer.

    • Improve efficiency and output

    1. The foam model used for the infiltration of aluminum alloy die castings is mechanically foamed. While ensuring the quality of the model, the production speed is also quite rapid.

    2. The infiltration process of aluminum alloy die castings simplifies the cumbersome steps of the traditional process, such as molding the core, which is laborious and inefficient.

    3. The aluminum alloy dies castings are impregnated into one box for multiple injections, and multiple boxes can be poured at the same time until the metal solution is used.

    • Cost-saving

    1. The mold used for the infiltration of aluminum alloy die castings can be used for life with almost no loss, reducing or eliminating mold costs.

    2. The impregnation of aluminum alloy die castings abandons the traditional molding process of core-setting, which saves labor and reduces manufacturing costs.

    3. The infiltration of aluminum alloy die castings have gradually developed from the foundry industry with many male workers to many female workers. Also, labor is greatly reduced in all aspects, and the cost of workers' wages is reduced in disguise.

    4. The sand used for infiltration of aluminum alloy die castings can be recycled, and the loss is 2%-5%.

    The impregnation treatment is to immerse the die-casting parts in an impregnating liquid with penetrating and filling functions, so that the impregnating liquid penetrates the loose parts inside the die-casting parts, thereby improving the air-tightness of the die-casting parts.

    1. Mold design

    Try to avoid sharp corners in the mold design, and the positions of holes and slots should be arranged reasonably.

    2. Selection of die steel

    The selection of die steel must complete the use of heat treatment to eliminate carbide segregation, refine carbide, and uniform structure.

    3. Cooling and lubrication

    The cooling and lubrication of the mold are to reduce the thermal load of the mold and avoid the mold temperature from being too high. It is usually forced to cool the mold during the intermittent operation, which will cause the mold's periodic heating and chilling action to cause thermal fatigue cracks. Therefore, the mold should be slowly cooled after use, otherwise, thermal stress will occur, which will cause the mold to crack and fail.

    4. Die casting and maintenance

    The mold should be fully preheated before die casting. If the preheating temperature is too high, the temperature of the mold is too high during use, the strength is reduced, and plastic deformation is easy to occur, causing the mold surface to collapse; the preheating temperature is too low when the mold starts to use, the instantaneous surface temperature changes greatly, and the thermal stress is large. Initiation of cracks.

    Ⅰ. The advantages of aluminum electric motor housing


    The aluminum electric motor housing has good ductility and low specific gravity, and also has the advantages of light weight, high strength, good heat dissipation performance, beautiful surface, corrosion resistance, and cutting-free inner bore. When installing the motor, the wiring of the motor is important. If the wires are connected incorrectly, it may bring a series of unnecessary troubles. In the process of wiring, the aluminum electric motor housing should be grounded, otherwise, the harm will be very serious.


    Ⅱ. Why is it harmful if the aluminum electric motor housing is not grounded?



    1. When the insulation of the motor stator winding is poor, aging or when the stator winding collides with the aluminum electric motor housing, the housing will be charged, and has a high voltage to the ground.


    2. If the motor does not have a grounding wire, a strong current will flow into the ground through the human body when touching the aluminum motor housing, causing personal injury or death.
