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.

Casting mold is one of the most important process equipment in casting production, which has a great influence on the quality of castings.

It has been applied to hardware and the entire mechanical and electronic industry, etc., and its use is becoming a trend of continuous expansion.

Inspection should be strengthened before die-casting to reduce parts with serious defects such as water marks on the product surface, pores, and pinholes, so as to ensure the compactness of die-casting parts.
