Die casting molds are generally divided into high-pressure die casting and low-pressure casting.
The primary material for die casting molds is aluminum alloy, with magnesium alloy and zinc alloy becoming increasingly common in recent years.
High-pressure die casting mainly produces automotive engine blocks, transmission housings, and one-piece molded car doors, among other products.
Low-pressure casting most commonly produces aluminum alloy wheels.
Generally, the failure mode of die casting molds is early cracking, which is closely related to the quality of the mold steel and the operating conditions. Currently, the quality of die casting mold steel from well-known brands is similar; the key factors are the heat treatment process and equipment, as well as the operating conditions. Whether or not a mold temperature controller is used has a significant impact on the mold's lifespan.
