Characteristics of Zinc Alloy Materials

Zinc alloys are ideal for small, detailed parts, flowing easily into molds while maintaining tight tolerances. They are durable, cost-effective, and commonly used in electronics, connectors, locks, hardware, and automotive components.

  • Zinc Alloy 2
  • Zamak 3
  • Zamak 5
  • Zamak 7
  • ZA-8
  • EZAC
  • ZA-27

Why Choose Zinc Die Casting?

Pros of Zinc Die Casting:

  • High Precision & Tight Tolerances: Ideal for complex shapes and detailed components with accurate dimensions.
  • Excellent Mold Flow: Flows smoothly into molds, making it perfect for thin walls and intricate designs.
  • Superior Surface Finish: Smooth cast surfaces reduce the need for secondary finishing operations.
  • Cost-Effective for Medium to High Volumes: Optimized for batch production while maintaining quality.
  • Strong & Durable: Provides reliable mechanical performance for connectors, electronics, and hardware components.

Cons of Zinc Die Casting:

  • Size & Weight Limitations: Best suited for small to medium-sized parts.
  • Limited Material Options: Only specific zinc alloys are available.
  • Porosity Risks: Air pockets may reduce strength or surface quality.
  • High Initial Tooling Costs: Mold and equipment investment is significant.
  • Design Constraints: Must follow wall thickness, draft angles, and other casting rules to avoid defects.

What Is Zinc Die Casting?

Zinc die casting is a manufacturing process where molten zinc alloy is injected under high pressure into a steel mold, also known as a die. This process creates strong, precise, and durable parts with excellent surface finishes.

Zinc die casting is ideal for producing complex, detailed components in large quantities—especially for industries like automotive, electronics, and hardware. Zinc alloys flow easily into molds, allowing for thin walls, intricate shapes, and tight tolerances while maintaining strength and dimensional accuracy.
