In the automotive sector, the primary manufacturing processes for aluminum alloys are stamping, die casting, and extrusion molding. Among these, die casting is the predominant production method for aluminum alloy components, accounting for approximately 80% of their usage in the automotive field. Extrusion and rolled parts each comprise about 10%. In response to environmental and energy-saving demands, the automotive industry is increasingly moving towards lightweight manufacturing, promoting the extensive use of low-density, high-strength materials such as aluminum and magnesium alloys in automotive aluminum parts.
The die casting industry is evolving towards precision, customization, high-tech innovation, and environmental sustainability. It is closely following the market trends of new energy vehicles, focusing on technological innovation to continually enhance its competitive edge within the industry chain.
Precision and High Performance
With the rapid development of the automotive industry, especially new energy vehicles, the requirements for the quality, precision, and performance of die-cast parts are increasing. These components must meet complex internal structural design needs and, while ensuring strength, rigidity, and heat resistance, aim for more refined surface treatments and aesthetic quality.
Customization and Enhanced R&D Production Capabilities
Downstream automotive parts manufacturers and components suppliers have an increasing demand for personalized die-cast components. This requires die-casting companies to possess strong research and development capabilities and extensive production experience to quickly design and produce customized products based on specific needs.
Capital and Technology Intensive
Due to the customization and high precision nature of the die-casting industry, there is a high requirement for investment in technology and equipment. Companies need to continuously introduce advanced die-casting equipment, precision processing equipment, and R&D testing instruments, while also cultivating professional R&D teams to adapt to ever-changing market demands and technological innovations.
Strong Demand from the New Energy Vehicle Market
Driven by China's "dual carbon" policy, the production and sales of new energy vehicles are experiencing explosive growth. This increases the demand for lightweight materials like aluminum and magnesium alloys in the manufacturing of automotive parts. The preference for using die casting technology to produce the body and parts of new energy vehicles to reduce weight and improve energy efficiency creates vast market space and development opportunities for the die-casting industry.
According to their functional use, aluminum alloy die castings in the automotive industry are applied in structural parts, load-bearing parts, safety parts, and decorative parts, including the following areas:
Power Transmission System: Cylinder blocks, cylinder block covers, cylinder head covers, crankcases, cylinder head cover lids, oil pans, alternator housings, engine gear rooms, various engine brackets, transmission housings, transmission brackets, etc.
Steering System: Chain covers, rack housings, and turbine housings.
Chassis Assembly: Suspension brackets and cross members.
Body: Wheels, frameworks, and decorative products.
Others: Lower end caps of shock absorbers, compressor brackets, clutch pedals, and brake pedals.
Aluminum alloy die castings are extensively used in the automotive industry. Currently, the widely adopted high-pressure die casting process for aluminum alloys in the die casting industry facilitates the processing of complex-shaped components, effectively improving production efficiency and reducing costs, thus being favored across various industries. The utilization ratios of various aluminum alloy processes in automobiles are approximately: casting 77%, rolling 10%, extrusion 10%, and forging 3%. The casting process is the most crucial processing method for automotive aluminum alloys. Learn more from the China aluminum alloy die casting factory-EMP.
