Casting Special Paintball Gun Pull rod

Characteristic of Casting Special Paintball Gun Pull rod:

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 Die-casting Special Pull rodmaterial 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 highrigidity and normaldimension 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 toys, light parts, decorations and part of the electric parts.

No.5: Good fluidity and good mechanical properties, high wear resistance. It applied to the zinc die casting part which has requirements of mechanical strength. Such as auto parts, mechanical and electrical parts, machinery parts, electrical components.
