Hard anodizing is a kind of processing service. The surface of products treated by hard oxidation is more beautiful. With more and more hard anodizing processing of aluminum precision parts, what are the cleaning methods for aluminum precision parts after hard anodizing?
No. 1 Cleaning Method for aluminum die casting parts after hard anodizing：
After degreasing aluminum surface treatment water washing, aluminum anodizing coloring is intended to prevent the grease of the failed products and affect the stability of the plating solution.
Aluminum precision hard anodizing, to wash off the residual liquid film alkali corrosion on the surface of aluminum concentrated alkali corrosion tank, water washing alkali corrosion needs to be cleaned at least three times. Due to the difficulty of cleaning, it is recommended that sink water be used to reduce the time of change and ensure a certain temperature and alkalinity, which is conducive to cleaning products.
No. 2 Cleaning Method for aluminum die casting parts after hard anodizing：
Electropolishing after chemical washing: in the two water cleaning lines, aluminum hard anodizing stain washes viscous liquid drugs appear on the cast aluminum surface, which indicates that the first tank should ensure a certain temperature so that the second tank can be used to clean the product with circulating water so that the effect will be better.
