the processes of die casting

Die casting: It is the use of high pressure to press molten metal into a precision metal mold cavity at high speed, and the molten metal cools and solidifies under pressure to form a casting.

Process characteristics

Advantages: 

1. During die casting, the metal liquid bears high pressure and has a fast flow rate. 

2. The product has good quality, stable size, and good interchangeability; 

3. High production efficiency and frequent use of die-casting molds; 

4. Suitable for mass production with good economic benefits.

Disadvantages: 

1. Castings are prone to small pores and shrinkage porosity. 

2. Die castings have low plasticity and are not suitable for working under impact loads and vibrations; 

3. When using high melting point alloys for die casting, the mold life is low, which affects the expansion of die casting production.

Application: 

Die castings were first used in automobile industry and instrument industry, and then gradually expanded to various industries, such as agricultural machinery, machine tool industry, electronic industry, Arms industry, computers, medical devices, clocks, cameras, and daily hardware.
