Processing Technology of Die Core of Aluminum Alloy Die casting Mould

The surface quality of aluminum alloy die casting parts is a key factor to determine the appearance of the parts. Although aluminum alloy material has good corrosion resistance, when it is exposed to air for a long time, the surface will become very non-smooth and may corrode. Therefore, for aluminum alloy die casting, moderate surface treatment technology is essential. Spraying is generally a widely used surface treatment method, which can improve the surface quality of aluminum alloy profile parts, make them more beautiful and generous, and also improve corrosion resistance.

Aluminum alloy die casting parts are generally used in the manufacture of automobile engines, airport engine parts and other common parts. The surface of such parts is often subjected to extreme environments, including continuous high temperatures, vegetable oils, corrosion and so on. Therefore, in order to improve the corrosion resistance of such parts, spray surface treatment processes are generally used. Spraying can form a strong protective layer, so that the aluminum alloy profile parts are not easy to corrosion, extend the service life.

After the aluminum alloy die-casting is completed, the selection of spraying surface treatment process can effectively improve the surface quality of the parts and improve its corrosion resistance. However, before spraying, the surface problem of aluminum alloy profiles must be solved accordingly to ensure spraying quality and durability. Since aluminum alloy profile parts are generally used for precision solid and automotive parts, the match between spraying and aluminum alloy profiles should be attached great importance, because high-quality operation methods can improve the corrosion resistance and service life of parts at any time.
