Products Description
The door handle was Prototype Zinc Die Casting. Parts casted in zinc materials have a very good surface look, and also suitable for post surface finish treatment, like mirror polish finish, chrome, and gold imitation. Good choice for components that have requirements for structural strength, complex shapes and surface decoration. We can do from prototypes testing to volume production with our various production capabilities.
---------------------------Mold Production Capabilities-------------------------
At XC Precision, our molding services only focus on rapid tooling and low volume production. We can provide molds like Rapid Injection Mold, Die Casting Mold, Silicone Mold, Sheet Metal Stamping Mold…The raw materials can be plastic to aluminum alloy or metal plate…Tolerance and other requirement and Qty are flexible as your request.
What Surface Treatments Can be done for Die Casting Parts
Powder Coating: Rich colors, strong adhesion, good corrosion resistance.
Electrophoresis Coating: Uniform film, excellent salt spray resistance.
Anodizing: Specially for aluminum alloy, hard and wear-resistant layer.
Polishing / Mirror Polishing: High gloss finish for decorative parts.
Sandblasting / Shot Blasting: Matte texture, removes burrs and improves coating adhesion.
Electroplating (Chrome, Nickel, Zinc): Bright surface, excellent rust resistance.
Passivation: Simple anti-rust treatment for structural components.
Silk Screen Printing / Laser Engraving: For logos, characters and marking.
How to Choose Zinc Alloy or Aluminum Alloy Die Casting?
|
Comparison Item |
Zinc Alloy |
Aluminum Alloy |
Key Decision Points |
|
Density (Weight) |
6.7 g/cm³ (Heavy) |
2.7 g/cm³ (Lightweight) |
Aluminum suitable for weight-sensitive applications |
|
Melting & Die-Casting Temperature |
Melting point ~385°C (Low temperature) |
Melting point ~660°C (High temperature) |
Zinc alloy offers longer mold life and lower thermal cracking risk; aluminum alloy imposes high thermal shock on molds. |
|
Minimum Wall Thickness |
0.6 mm (Ultra-thin) |
1.0 – 1.5 mm |
Choose zinc for ultra-thin walls or precise micro-structures (e.g., electronic connectors). |
|
Surface Finish |
Excellent for electroplating, painting, and brushing |
Mainly for spraying and anodizing; electroplating is difficult |
Choose zinc for decorative finishes such as mirror finish, chrome, and gold imitation. |
|
Corrosion Resistance |
Moderate; requires electroplating or passivation protection |
Excellent; naturally forms an oxide film |
Aluminum is more reliable for outdoor or humid environments. |
|
Unit Cost |
Higher raw material cost, but supports thin walls and long-life molds |
Lower raw material cost, but may require more post-processing |
Zinc is cost-effective for small, complex parts; aluminum is cheaper for large, simple parts. |
