| Abstract: | By virtue of visualization equipment in injection molding, three kinds of cavities were constructed. Under certain conditions, the forming process of weld line defect was observed. Via studying the forming mechanism, the weld line defect was eliminated or reduced by improving packaging pressure, melt temperature, and injection velocity. The study results could provide theoretical basis for investigating and avoiding product defects in injection molding process. |
