Our Zinc Die Casting Surface Finish Services
- Polishing and Buffing: Polishing and buffing processes can result in a smooth and shiny surface finish. This treatment is suitable for parts that require a high level of smoothness and a flawless appearance.
- Sandblasting: Sandblasting involves propelling abrasive particles onto the surface of the zinc die casting parts using high-pressure air or other methods. It creates a matte or textured surface effect, which can enhance the aesthetics and hide surface defects.
- Plating: Plating is a common surface treatment for zinc die castings. It involves depositing a layer of metal, such as chrome, nickel, or zinc, onto the surface of the part. Plating enhances the corrosion resistance of the part and provides a decorative finish.
- Painting and Powder Coating: Painting and powder coating are popular surface finishes that offer a wide range of color options. These finishes provide an additional protective layer, improve durability, and enhance the appearance of zinc die casting parts.
- Anodizing: Anodizing is a process that involves creating an oxide layer on the surface of the zinc die casting part. This treatment enhances corrosion resistance, improves surface hardness, and can provide different color options.

Zinc Die Casting vs Aluminum Die Casting
The choice between die cast zinc and aluminum depends on several factors, including the specific requirements of the application and the desired characteristics of the final product. Both processes have their own advantages and considerations. The following is a comparison of zinc die castings and aluminum die castings:
| Zinc Alloy Die Casting | Aluminum Alloy Die Casting | |
| Mechanical Behavior | higher impact strength | good strength to weight ratio, lighter weight and better thermal conductivity |
| Precision and Complexity | high precision, can produce complex parts | high precision, not suitable for extremely complex parts |
| Surface Finish | smooth and even | surface treatment required |
| Corrosion Resistance | good corrosion resistance, suitable for outdoor and corrosive environments | additional protective coating or treatment required to enhance its corrosion resistance |
| Cost | lower mould cost | high mould cost |
Advantages of Zinc Die Casting
- Excellent Dimensional Accuracy: zinc die casting provides high precision and dimensional stability, allowing the production of highly complex parts with tight tolerances, thin walls, and reduced draft angles.
- Excellent Mechanical Properties: zinc die casting products have high strength and hardness, good impact resistance and excellent dimensional stability.
- Excellent Surface Finish: zinc alloy die casting parts has a smooth, uniform surface finish. The mould used in the process creates complex details and textures on the part, eliminating the need for additional surface preparation or finishing operations.
- Good Corrosion Resistance: zinc die casting parts are suitable for outdoor and corrosive environments.
- High Thermal Conductivity: zinc’s high thermal conductivity allows for efficient heat dissipation, making it suitable for applications where thermal management is critical, such as electronic enclosures and heat sinks.
- High Production Efficiency: with high productivity and shorter lead time.
- Cost Effective Production: relatively low cost of zinc alloy die casting mould, high production efficiency, lower melting point than other metals that can save energy during the casting process.
- Recyclability: high pressure zinc die casting waste can be easily melted down and reused without any quality loss.
What Is Zinc Die Casting?
Zinc die casting is a manufacturing process in which molten zinc is injected into a mould cavity under high pressure to produce complex-shaped components with high precision and excellent surface finish.
The process begins by melting a high-quality zinc alloy, usually composed of zinc with small amounts of aluminium, copper and magnesium. The molten metal is then injected into the steel mould using a dedicated zinc die casting machine. The high pressure applied by the machine ensures that the molten metal fills all the complex features of the mould, capturing every detail of the desired part.
Once the molten zinc alloy has solidified inside the mould, the mould is opened and the newly formed zinc die casting part is ejected. The part is then subjected to various post-processing treatments such as trimming, deburring, surface finishing and machining as required to obtain the desired end product.
Zinc Die Casting Material
Different die casting zinc material has different properties, the most commonly used die casting zinc alloys include:
- Zamak 3: zamak 3 has excellent fluidity, high strength and good corrosion resistance. It is commonly used for general purpose zinc die casting components in industries such as automotive, electronics and consumer goods.
- Zamak 5: zamak 5 has higher strength and stiffness compared to Zamak 3, making it suitable for applications requiring higher structural integrity. It is commonly used in automotive and industrial applications.
- Zamak 2: zamak 2 is known for its excellent castability, dimensional stability and good impact strength. It can be used in a variety of industries including automotive, electrical and home appliances.
- ZA Alloy: za alloy, also known as zinc-aluminum alloy, is a zinc alloy with a high aluminum content. This alloy has increased strength, hardness and creep resistance compared to standard zinc alloys. They are often used in applications requiring higher mechanical properties.
- ZP Alloy: zp alloy or zinc-aluminum-copper alloy is a zinc alloy with a high copper content. These alloys have improved mechanical properties, higher hardness and higher wear resistance. They are often used in applications where strength and durability are critical.
- Other Alloys: in addition to the above alloys, there are various special zinc alloys available for specific applications. These include alloys with additives such as nickel, lead or tin to achieve specific properties such as increased corrosion resistance or enhanced machinability.
