Hot Chamber Die Casting
Highly efficient for low-melting-point metals like zinc and magnesium, this method integrates a furnace with the casting machine for fast, continuous production.
Molten metal is directly injected from the heated chamber into the mold, ensuring precise dimensions and superior mechanical properties.

Cold Chamber Die Casting
Ideal for high-melting-point metals like aluminum and copper alloys, this process involves manually loading molten metal into a cold chamber before injection.
It protects equipment from extreme heat, ensuring durability while producing strong, complex parts.

Surface Finishing for Die Casting
Select from our range of surface finishes to enhance corrosion resistance and add vibrant colors to your die-cast parts.
Types | Description |
---|---|
As Cast | Provides a basic, functional finish with smooth surfaces and minor tool marks, ideal for non-cosmetic uses. |
Polishing | Improves surface smoothness and shine, reducing roughness for a high-gloss, visually appealing finish. |
Sand Blasting | Achieves a uniform, matte finish by blasting the surface with fine particles, removing imperfections and prepping for further treatments. |
Anodizing | Enhances corrosion resistance and wear properties of aluminum, offering color options for added durability and aesthetics. |
Powder Coating | Applies a thick, uniform coating that is more durable than traditional paint, perfect for vibrant colors and added protection against corrosion. |
Brushed Finish | Creates fine lines on the surface, helping to conceal fingerprints and minor scratches while adding a practical and aesthetic touch. |
