Analysis Of Material Failure Reasons For Plastic Molds

The general process of mold manufacturing includes mold design, material selection, heat treatment, mechanical processing, debugging, and installation. According to the survey, the materials and heat treatment used in the mold are the main factors affecting its service life among the factors that lead to mold failure. From the perspective of total quality management, the factors that affect the service life of molds cannot be measured as the sum of polynomials, but should be the product of multiple factors. Therefore, the quality of mold materials and heat treatment is particularly important in the entire mold manufacturing process.
From the analysis of common phenomena of mold failure, plastic molds can experience wear failure, localized deformation failure, and fracture failure during service. The important failure forms of plastic molds can be divided into wear failure, local plastic deformation failure, and fracture failure.
