The coating of aluminum die castings includes mold release agents and lubricants. When choosing precision coatings, you should choose according to the surface treatment method and quality requirements of die castings. So what is the role of die casting coatings?

1. Spraying of aluminum die castings can protect the mold. Spraying can reduce the mold temperature. By dissipating heat, the mold temperature can be reduced to avoid damage to the mold caused by high temperature and extend the life of the mold.

2. Aluminum die casting coatings can protect punches, ejectors and other moving parts. It helps to reduce the wear of punches, ejectors and other parts.

3. Aluminum die casting coatings are conducive to the smooth demolding of die castings. Spraying mold release agents are conducive to the smooth demolding of die castings and avoid sticking.

4. The coating of aluminum die castings can ensure the smooth filling of molten metal. Spraying can play a role in filling and circulating molten metal, avoid sticking to a certain extent, and ensure the molding of die castings.

The above is the role of aluminum die casting coatings. If the wrong coating is selected, there will be casting defects such as pores, sticking, and bubbling. So please choose the coating carefully and be sure to choose the correct coating.
