How to choose the eligible plastic mold for production requirement?
Blank plastic degeneration of the plastic mold cavity along the cavity surface is both flow and slide, so that generated intense friction between the cavity surface and blank, resulting in mold wear and failure. Therefore, the wear resistance of the material is to mold the most basic, one of the most important performance.
The hardness is the main factor of impact abrasion resistance. Under normal circumstances, the higher the hardness of the mold parts, the smaller the amount of wear, wear resistance, the better. In addition, the wear resistance of carbide material types, quantity, shape, size and distribution.
Mostly very poor working conditions of the mold, some often bear a greater impact load, leading to brittle fracture.
