(Summary description)Do you know the basic principles that need to be achieved when selecting materials for injection molds? If you are still unclear, let's take a look at it with the editor now.
1. Abrasion resistance
During the plastic degeneration of the blank in the cavity, the blank flows and slides along the surface of the cavity, causing friction between the surface of the cavity and the blank. Therefore, the wear resistance of the material is one of the most basic and important properties of the mold.
The main factor affecting wear resistance is hardness. Generally, the higher the hardness of injection mold parts, the smaller the wear and the better the wear resistance.
2. Toughness
Most of the researches on the working environment conditions of the mold are very harsh, and some of them are often able to withstand large impact loads, which can lead to brittle fracture. In order to prevent sudden brittle fracture of mold design parts during work, the mold must have relatively high strength and toughness.
The toughness of the mold mainly depends on the carbon content, grain size and microstructure of the material.
3. Fatigue fracture performance
In the development process of mold design work, under the long-term influence of cyclic stress, it can often lead to fatigue and fracture of students. Its forms include small energy fatigue fracture through multiple impacts, tensile fatigue fracture, contact fatigue fracture, and bending fatigue fracture.
