Zinc alloy die casting die preheating must pay attention to these five points

　　In the process of zinc alloy die casting, there are many ways to preheat die casting molds, but we must pay attention to these five points:

　　1. The heating should be uniform, and the preheating chamber must return the push rod to the molding position in the mold.

　　2. The preheating temperature of the core should reach the temperature of continuous production.

　　3. The pressure chamber and injection heavy head should also be preheated, and it should not be preheated with high temperature metal liquid.

　　4. The die casting mold should be cleaned and lubricated after preheating.

　　5. Pass the coolant in time before preheating, otherwise the die casting mold will crack or even break due to chilling.

　　After die-casting aluminum parts are produced, how to check whether the quality of the products is qualified?

　　1. Die-cast aluminum must be a complete individual. There shall be no defects, cracks, bubbles and other defects, and there shall be no mold phenomenon.

　　2. The gate and flashing part of the casting should be erased frequently and kept clean at all times.

　　3. The defects that cannot appear on the processing surface are mixed with impurities, and the pores are sparse.

　　4. The processing mark level on the top of the aluminum part should not exceed 0.2mm.
