Generally, the service life of Zinc alloy die casting die is 200,000 to 300,000 mold times for alloy structural steel, and 1 million mold times for die steel. The level of overseas zinc alloy die-casting molds is basically 300,000 to 500,000 molds, and some can reach 1 million molds.

Zinc alloy die casting die is a mold used to produce zinc alloy parts of various shapes. It consists of cavity, parting surface, pouring system and cooling system.

In the process of Zinc alloy die casting, the filling mode of molten metal is one of the key factors affecting the quality of castings. Many die-casting defects, such as insufficient pouring, cold shuts, pores, and shrinkage, are related to the filling mode. At the same time, the filling mode is also One of the key factors affecting mold life.

The main additive elements of Zinc alloy die casting are aluminum, copper and magnesium. Zinc alloys can be divided into deformation and cast zinc alloys according to the processing technology. Cast zinc alloys have good fluidity and corrosion resistance, and are suitable for die-casting instruments, automobile parts casings, etc.

Zinc alloy die casting is an alloy composed of zinc as the base and adding other elements. Often added alloying elements are aluminum, copper, magnesium, cadmium, lead, titanium and so on. Zinc alloy has a low melting point, good fluidity, easy welding, brazing and plastic processing.

If we want to produce high-quality zinc alloy die castings, we must start from the raw materials. So, what kind of problems will the poor materials cause zinc alloy die castings?
