How much do people know about the standards for qualified injection molding molds?

Plastic products are basically produced using injection molding equipment, but during this process, injection molding molds are used. The quality of the molds can directly affect the quality of the injection molded products. Let's take a look at the standards for qualified injection molding molds.
1. Wear Resistance
1. When the blank undergoes plastic deformation in the cavity of the injection molding mold, it moves and slides along the outside of the cavity, causing intense friction between the outside of the cavity and the blank, which leads to wear and tear on the mold.
2. The wear resistance of the mold is one of the important points. Hardness is a key factor affecting wear resistance.
3. Generally, the higher the overall hardness of the mold, the less wear it experiences, and the better its wear resistance. Additionally, wear resistance is also related to the type, quantity, state, size, and distribution of carbides in the material.
2. Toughness
1. The working conditions of injection molding molds are often very harsh, and some are subjected to significant impact loads, which can lead to brittle fractures. To prevent sudden brittle failure of the mold during operation, precision metal molds must have high strength and toughness.
2. The toughness of the mold mainly depends on the carbon content, grain size, and structural condition of the material used in precision mold manufacturing.
