Heat treatment of aluminum alloy die casting mold can be done without equipment

　　Aluminum alloy die casting die in the process of processing, usually need to multi-pass through multi-pass heat treatment, which can eliminate the internal stress of aluminum alloy die casting die, improve the performance of die casting die, die casting die life is very good, but if the aluminum alloy die casting die exposed to air heating to high temperature, die casting die will appear oxidation decarburization phenomenon, resulting in die casting die scrap.

　　Equipment that can prevent the oxidation and decarburization of aluminum alloy die casting mold heat treatment are vacuum furnaces, reducing gas (CO) furnaces, inert gas (N2 or Ar) furnaces, salt bath furnaces, etc., but the price of these equipment is very high, so if the lack of these ideal heating equipment, can we do the heat treatment of aluminum alloy die casting mold?
