Considerations About Thin Wall Plastic Mold
In recent years, with the development of thin-walled parts, thin-wall injection molding technology has been highly valued by people, which has promoted the development of thin wall plastic mold in thin-wall injection molding.
In the process of making thin wall plastic molds, we need to determine the factors added in thin wall injection molding and properly consider these factors. Some factors that can be ignored in conventional injection molding tend to have a greater impact on the melt flow of thin-wall molding. For example, viscosity has a significant dependence on the pressure in thin-walled injection molding, but not in conventional injection molding; weld line strength has a great influence on the performance of plastic parts, especially thin-walled plastic parts, weld line strength, and temperature and pressures Relevant, but the influence of pressure is not considered in the conventional numerical simulation; the specific heat, heat transfer coefficient and pressure loss of the material. Because the existing commercial numerical simulation software ignores these influencing factors, there will be inconsistencies when predicting the filling of thin-wall injection molding.
