What kind of material is used to open the injection mold?Issuing time:2021-05-27 14:27 What material is used for injection mold opening? First of all, we need to understand the impact of injection mold material on the mold? 1）Influence on service life of injection mold Generally, if the material with high hardness is used to open the mold, the service life of the corresponding mold will be relatively high. For example, if the steel with heat treatment hardness of HRC50 is used, the service life of the mold can reach 500000 to 1 million mold times. Otherwise, it is easy to wear, and the injection product is easy to be out of tolerance. Therefore, the selected steel should not only have good heat treatment performance, but also have good cutting performance in the state of high hardness. 2）Influence of plastic raw materials on steel The raw materials for injection molding and the fillers added have a great influence on the steel, especially the wear of glass fiber on the injection mold. In addition, some plastic materials are corrosive and need to be considered comprehensively before choosing mold opening materials. |
