Zinc Die casting

What is  Zinc Die Casting Process?


The basic die casting process consists of injecting molten metal under high pressure into a steel mold called a die.

Advantages of Pressure Zinc Die Casting China :
1. Zinc Die Casting  Lower costs compared to other processes.

2. Economical – typically production of any number of components from thousands to millions before requiring replacement is possible.

3. Castings with close dimensional control and good surface finish

4. Castings with thin walls, and therefore are lighter in weight

5.Excellent EMI/RFI shielding characteristics.
