Mold for Zinc Die Casting
Zinc alloy has low melting point and good fluidity for easy die casting.
It features high precision, fine surface, great toughness, perfect plating performance and low cost.
High hardness, good thermal conductivity, smooth cavity surface, wear resistance, anti-sticking, simple cooling structure and long service life for zinc alloy die casting.
What are the properties of Zinc?
- Low melting point, easy for die-casting forming
- Good casting fluidity, high product precision
- Good mechanical strength and toughness
- Excellent surface electroplating and spraying performance
- Good corrosion resistance
- Low cost and easy availability of raw materials
Technologies of Molds for Zinc
- High surface finish of cavity
- Optimized cooling channel design
- High hardness and heat-resistant mold steel
- Precise venting system
- Reasonable draft angle
- Wear and erosion resistant structure
Correspondence of Zinc Alloy Grades in Different Regions
Key Mold Points for Different Grades of Die-Casting Zinc Alloys
Different grades of zinc alloy have different requirements for die-casting molds, and the molds cannot be fully universal.
Zamak 3 & Zamak 5: Similar performance, low melting point and good fluidity, low erosion and corrosion to molds. Ordinary H13 mold steel is applicable.
Their molds can be used interchangeably temporarily by adjusting casting temperature, injection speed and cooling parameters.
Zamak 2: Higher copper content brings stronger molten alloy erosion and larger shrinkage.
It requires better nitriding surface treatment for molds. It is not recommended to share molds with Zamak 3 or Zamak 5.
ZA8 / ZA12 / ZA27 high-aluminum zinc alloy: High aluminum content and high melting point cause heavy thermal load and strong erosion to molds.
They require higher shrinkage tolerance, larger venting slots and bigger draft angles.
Premium heat-resistant and anti-corrosion mold steel is mandatory.
Their molds are completely incompatible with conventional Zamak molds.
