Types of Die Casting Processes
We primarily apply hot and cold chamber casting.

Cold Chamber Die Casting
Cold chamber die casting is ideal for high-melting-point metals like aluminum and copper alloys. In this process, molten metal is manually poured into a cold chamber before injection. This approach protects the machinery from extreme heat, improving durability and performance. It is especially suited for producing large, robust parts with intricate designs and excellent strength.

Hot Chamber Die Casting
This is highly efficient for metals with lower melting points such as zinc and magnesium. It features a furnace integrated with the casting machine, allowing quick and continuous cycling. The molten metal is injected directly from the heated chamber into the mold, making it ideal for manufacturing components that demand precise dimensional accuracy and superior mechanical properties.

Mold Design and Fabrication
· 10 experienced engineers capable of designing and optimizing die casting molds.
· Complex geometries and thin-walled structures can be achieved.
· Our factory uses advanced 4-axis and 5-axis CNC machines to manufacture molds.
Materials Used For Die Casting
Most die castings are made up of non-ferrous metals.
There are three most common materials used for die casting,including:

Aluminum Alloys
A360, A380, A390, A413, ADC-1, ADC-12
Aluminium die cast alloys are lightweight and can withstand some of the highest operating temperatures. Its great strength-to-weight ratios, make it popular for automotive components and aerospace applications.

Zinc Alloys
Zamak-2, Zamak-3, Zamak-5, Zamak-7, ZA-8, ZA-12, ZA-27
Zinc die cast alloys are typically lower in cost compared to aluminium and magnesium. They offer good stability and have excellent electrical and thermal conductivity, making them popular for under-the-hood parts and electrical applications.

Magnesium Alloys
AZ91D, AI60B, AS41B
Magnesium die cast alloys are strong, rigid materials that have good corrosion resistance. They are typically used for electronic products.
Die Casting Surface Finishes
Die-cast components often undergo surface treatments to enhance their appearance, durability, and functionality.
The choice of surface treatment depends on the desired appearance, functionality, and material of the die-cast component.
