Gas marks are a relatively common molding defect in the injection molding industry. Whether on precision plastic parts or large automotive and home appliance molds, they often trouble injection molding manufacturers. Because gas marks are a rather subjective appearance defect, it is difficult to express them directly through software; therefore, Moldflow analysis results do not offer a direct analytical result to display and predict this injection molding defect.

Using Moldflow software to analyze the average volumetric shrinkage rate of a product and simulate the injection molding process of appearance-part molds for 3C products. Through the injection flow analysis, the optimal gate location of the part is determined, and the locations of defects such as air traps and weld lines are predicted and displayed; combined with the changes in injection pressure and clamping force, filling process, temperature changes, and product molding quality analysis, it helps process engineers identify the causes of defects before trial molding, thereby improving mold structure design and product structure to increase the success rate of trial molding.
