Utilizing advanced die-casting techniques, we produce high-quality parts that consistently meet rigorous functional demands and aesthetic standards for contemporary architectural applications.
Zinc alloy die casting is a high-pressure metal casting process where molten zinc alloy (typically Zamak or ZA series) is injected into precision-engineered steel molds. The process involves:
Melting: Zinc alloy is heated to approximately 400°C in a furnace.
Injection: Molten metal is injected into the mold cavity under high pressure.
Cooling: The material rapidly solidifies into the desired shape.
Ejection: The finished part is ejected from the mold.
Trimming: Excess material (flash) is removed for a clean finish.
Zinc die-cast parts can be enhanced with various surface finishes:
Electroplating | Decorative chrome, nickel, or brass coatings for aesthetics and corrosion resistance. |
Powder Coating | Durable, wear-resistant layers available in multiple colors. |
Anodizing (rare for zinc) | Primarily used for aluminum, but specialized treatments exist for zinc. |
Painting | Custom colors and textures for functional or decorative purposes |
Polishing/Brushing | Achieves mirror-like or metallic textured finishes |
Passivation | Improves corrosion resistance without altering appearance |
