Plastic products are basically produced and manufactured through injection molding equipment
Plastic products are basically produced and manufactured through injection molding equipment, but injection molding molds are used in this process. The quality of molds can directly affect the quality of injection molded products. Let's follow the editor to take a look at the standards for qualified injection molding molds.
1、 Wear resistance
When the blank undergoes plastic deformation in the injection molding mold cavity, it moves and slides along the outside of the cavity, causing intense friction between the outside of the cavity and the blank, resulting in wear and tear of the mold.
2. Mold wear resistance is one of the important points. Hardness is an important factor affecting wear resistance.
Under normal circumstances, the higher the hardness of the entire mold, the smaller the wear and tear, and the better the wear resistance. In addition, wear resistance is not related to the variety, quantity, state, size, and dispersion of carbides.
2、 Strong resilience
1. The prerequisites for injection molding molds are mostly very poor, and some are often subjected to significant impact loads, leading to brittle fracture. To avoid sudden brittle fracture of the entire mold during operation, precision hardware molds should have high strength and toughness.
The toughness of the mold depends heavily on the carbon content, grain size, and structural condition of the material - precision mold manufacturing.
