What is the Die Casting?

Ⅰ. Die casting

Die casting is a manufacturing process in which molten metal is poured or pressed into a steel mold. Molds are also called tools. They are made of steel and are specially designed for different projects. Aluminum, zinc and magnesium are the most commonly used die casting alloys.

Ⅱ. Types of die casting process

According to the different requirements of users, different types of die casting process will be used. There are mainly three common die casting processes.

(1) High pressure die casting. In the high-pressure die casting process, molten metal or metal alloy is injected into the mold under high-speed and high-pressure conditions.

(2) Gravity die casting. Gravity die casting is one of the earliest invented die casting processes for metal and light alloy. In this fully automated process, molten metal can be poured directly into semi-permanent or permanent molds.

(3) Low pressure die casting. In low pressure die casting, the mold is filled with molten metal from a pressurized furnace, and the pressure in the mold is usually around 0.7 bar.

Ⅲ. Advantages of die casting process

The die casting process has significant advantages over other casting processes. It can greatly reduce the cost input, which is not only reflected in the price of the parts itself, but also in the significant drop in the total cost of production. In addition, the die casting process has the following other advantages.

1. Variable wall thickness

2. Low tolerance rate

3. Fewer steps

4. Fast production cycle

5. Reduce material scrap

6. Long service life
