What is the function of coating for aluminum alloy die-casting parts

　　The coatings for aluminum alloy die castings include release agents and lubricants. Due to different compositions and application fields, the selection of the exact coating needs to be based on the surface treatment method or quality requirements of the die casting, in order to play a corresponding role. So, what is the role of coating for die castings?

　　1. Protecting the mold: Spraying paint can lower the temperature of the mold, reduce the temperature of the mold through heat dissipation, avoid mold damage caused by high temperatures, and extend the lifespan of the mold.

　　2. Protecting the punch, top rod, and other moving parts: can effectively reduce wear on the punch, top rod, and other parts.

　　3. Beneficial for successful demolding of die-casting parts: Spraying demolding agents is beneficial for the smooth demolding of die-casting parts and avoids the occurrence of mold sticking problems.

　　4. Ensure smooth filling of metal liquid: Spraying paint can make the metal liquid fill smoothly, to some extent avoiding mold sticking and ensuring the formation of die-casting parts.
