Abstract: The application of dynamic visualization technique in injection molding process was introduced. Using the visualization experimental equipment in injection molding, the weld line defect was artificially constructed and recorded. The generation mechanism of the defect was analyzed and the weld line defect was depressed by changing processing condition.

Key words: injection molding, visualization, weld line, defect
