What Are the Requirements for Material in Die Cast Tooling Processing?

I. The quality of the die casting tooling material is related to the quality of the die casting tooling

There will be a variety of quality problems if the material used by the die cast tooling is of poor quality. It is necessary to start from the source to solve these quality problems in die casting tooling. Only by solving the quality problems of die cast toolig material can we improve the quality of die cast tooling.

In the process of die cast tooling, it will be irresistibly affected by the attack force, vibration force, friction force and other external forces, so the material must be able to withstand these external forces without being damaged. Therefore, it is necessary to request the material of die cast tooling processing.

II. The requirements for material in die cast tooling processing

1. Material requirements of drawing die:

(1) Excellent adhesion and adsorption;

(2) High wear resistance;

(3) High hardness;

(4) Corresponding strength and toughness;

(5) Relatively superior cutting disposal characteristics；

2. Material requirements of cold extrusion die: 

The material used in the sheet blanking die should have high wear resistance and high hardness. The material of the thick plate blanking die should have high wear resistance, pressure compliance point, fracture resistance, bending strength and toughness.

3. Material requirements:

(1) High strength;

(2) High hardness;

(3) High wear resistance;

(4) Good heat resistance;

(5) Very good thermal hardness.
