What is Die Casting?

Pressure casting is a metal casting method that involves using high pressure to inject molten metal into a precisely made mold, where it quickly cools and solidifies to form a part or semi-finished product with certain strength and shape.

How to choose the appropriate casting method?

Choosing the right casting method depends on factors such as the requirements for the casting, production volume, material properties, and budget. For example, for low-volume, complex-shaped parts, investment casting might be preferable due to its relatively lower tooling costs compared to die casting. For high-volume, simple-shaped parts, die casting could be a more cost-effective option.

What are the advantages and disadvantages of metal casting?

The advantages of metal casting include the ability to produce intricate shapes and precise dimensions, high material utilization rates, and suitability for mass production. However, the disadvantages include higher costs, particularly for mold construction, and the possibility of defects such as gas pores and inclusions in the castings.
