Main applications:

Mold accessories are widely used in various kinds of manufacturing fields, such as plastic mold, stamping mold, automobile, electrical and aviation.

Prerequisite editing:
1. Wear resistance
When the blank is plastic in the mold cavity, it flows and slides along the surface of the mold cavity, causing severe friction between the surface of the mold cavity and the blank, which leads to the failure of the mold due to wear. So the wear resistance of the material is one of the most basic and important properties of the mold.
Hardness is the main factor affecting the wear resistance. Generally, the higher the hardness of die parts, the smaller the wear amount and the better the wear resistance. In addition, the wear resistance is also related to the type, quantity, shape, size and distribution of carbide in the material.
2. Strong toughness
Most of the working conditions of dies are very bad, some of them often bear large impact load, which leads to brittle fracture. In order to prevent the die parts from brittle fracture, the die should have high strength and toughness. The toughness of die mainly depends on carbon content, grain size and microstructure.
3. Fatigue fracture properties
In the process of die working, under the long-term action of cyclic stress, it often leads to fatigue fracture. Its forms are small energy multiple impact fatigue fracture, tensile fatigue fracture contact fatigue fracture and bending fatigue fracture. The fatigue fracture performance of the die mainly depends on its strength, toughness, hardness and the content of inclusions in the material.
4. High temperature performance
When the working temperature of the die is high, the hardness and strength will decrease, which will lead to early wear or plastic deformation of the die and failure. Therefore, the die material should have high tempering stability to ensure that the die has high hardness and strength at working temperature.
5. Cold and hot fatigue resistance
Some dies are in the state of repeated heating and cooling in the working process, which makes the surface of the cavity subject to tensile and pressure stress, causes surface cracking and peeling, increases friction, hinders plastic deformation, reduces dimensional accuracy, and leads to die failure. Cold and hot fatigue is one of the main failure modes of hot working dies, which should have high cold and hot fatigue resistance.
6. Corrosion resistance
Some molds, such as plastic molds, because of the presence of chlorine, fluorine and other elements in the plastic, decompose and precipitate strong corrosive gases such as HCI and HF after being heated, which erode the surface of mold cavity, increase its surface roughness, and intensify wear failure.

Manufacturing materials:
The materials of Die accessories are usually tungsten steel, high speed steel, bearing steel, stainless steel, brass, metal alloy, spring steel, carbonized steel, etc.
