Abstract

The surface of an injection mold is prone to erosion and wear under the impact of the filler during plastics injection molding, which leads to premature failure of the mold. The mechanism of erosion and wear of a filler on the mold has not been clarified yet. A numerical technique was employed to simulate the erosion and wear process, and the influence of environmental parameters and particle characteristics, such as erosion velocity, erosion angle, temperature, and particle shape were studied. The results showed that the erosion velocity and erosion angle are important factors that affect erosion and wear. Finally, the relationship between change of particle energy and erosion and wear of the material is studied from the perspective of energy.
