Aluminum/zinc/magnesium die-casting die, die casting die design Aluminum alloy die-casting product production, processing and surface treatment, precision die-casting die, large difficult die-casting die, the basic process of die-casting is: the liquid metal first fills into the cavity of the die at low speed or high speed, and the die has an active cavity surface, which is forged under pressure with the cooling process of the liquid metal to eliminate the shrinkage defects of the blank, It also makes the internal structure of the blank reach the broken grain in the forged state. The comprehensive mechanical properties of the blank have been significantly improved.
