Background technique

A die-casting mold is a tool for casting metal parts. It is a tool that completes the die-casting process on a dedicated die-casting die forging machine. The basic process of die-casting is: the molten metal is first cast at low speed or high speed and filled into the cavity of the mold. The mold has a movable cavity surface, which is pressurized and forged along with the cooling process of the molten metal, which eliminates the shrinkage of the blank. The loose defects also make the internal structure of the blank reach the forged state of broken grains, and the comprehensive mechanical properties of the blank are significantly improved.
