Reseach on the Failure and Material Selection of Plastic Mold

The working conditions of the plastic mold are complex. They touch directly with the plastic, withstand the pressure, temperature, friction and corrosion and so on. The main failure modes of the plastic mold surface wear, deformation and fracture. The main failure reasons depend on working conditions, mold materials and heat treatment, etc. So material selection and heat treatment of the plastic mold are more important. Material selection of plastic mold is decided by their using performances. According to the mold types, material types and performance requirements, we select different heat treatment.
