Small zinc die casting part

Characteristic of Small zinc die casting part:  

1.       High specific density, more strength than plastic injection molding.

2.       Good casting performance, Producing complex shape and Thin-walled precision die casting parts, the surface of zinc die-cast part is smooth.

3.       Easy do the surface treatment: Plating, powder coating, Painting.

4.       Do not attract iron when Melt and die casting, do not corrosion zinc alloy die-cast part and Non-stick mold.

5.       Have good room temperature mechanical properties and wear resistance.

6.       Low melting point, Melts at 385℃, more easily forming than aluminum alloy die-casting molding.

Domestic commonly used Small zamak die-casting material performance:  

The traditional die-casting zinc alloy: No.2, No.3, No.5, No.7. ZA8 Currently the most widely used is zinc alloy No.3.

The application of commonly used zinc alloy:

No.2: It is used to those mechanical fittings that have special need in mechanical capability, and need high rigidity and normal dimension and precision.

No.3: Good liquidity and mechanical properties, and the best combination of mechanical properties, casting properties and economical. It applied to the die casting part which the mechanical strength requirement is not high. Such as to
