The application of release agent in the die casting mold
Die casting is a metal casting process that involves injecting molten metal materials into molds under high pressure and at high speed to produce target products. The main materials used in die-casting industries are alloys of aluminum, zinc, and magnesium. The working principle of the die casting mold is similar to that of plastic injection molds, so the phenomenon of mold sticking will also be meted, how to use the mold release agent correctly (take aluminum as an example)?
Common requirements of the release agent:
Oil. Silicone oil is an ideal material for release agents, it has high-temperature resistance and will not affect the assembly effect of die casting products.
Water. In the consistency of the release agent, water is used as the dispersion medium to ensure that the silicone oil is distributed on the surface of the cavity to improve the demolding effect.
Emulsion. Choose a suitable emulsifier to prevent it from carbonizing at a high temperature, ensuring the tidy of the product and mold.
No corrosive effect will be allowed in the release agent, and the volatiles contained are non-toxic and harmless to the human body.
