Injection molding CAE is employed to analyze the flow process of insert molding. The goals of the analysis are to reduce the number of injection processes required in injection molding, to impart greater added value to the product, and to advance injection molding technology. The importance of an analysis for the weld lines that occur when the mold is filled with plastic and that may lead to lower product quality in addition to an displacements in the insert-molded part due to plastic shrinkage is pointed out. This paper will report about the importance of the previous injection molding CAE for actual fabrication to investigate the product shape design and molding conditions.
