SURFACE TREATMENET
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
Zinc die-cast components are widely used in:
Automotive: Gearbox housings, brackets, decorative emblems, and fuel system parts.
Consumer Electronics: Connectors, heat sinks, smartphone casings, and structural components.
Hardware & Furniture: Door handles, locks, hinges, and decorative accessories.
Lighting: LED heat sinks, lamp bases, and outdoor lighting housings.
Industrial Machinery: Gears, pulleys, and wear-resistant components.
--High Precision: Capable of producing tight tolerances (±0.05 mm) and intricate details.
--Excellent Surface Quality: Naturally smooth surfaces reduce the need for extensive post-processing.
--Cost-Effectiveness: Low melting point reduces energy consumption; high production speeds lower per-unit costs.
--Superior Mechanical Properties: Combines high strength, hardness, and impact resistance, even in thin-walled sections.
--Recyclability: Zinc alloys are 100% recyclable without degradation of properties.
--Corrosion Resistance: Suitable for harsh environments with proper coatings.
