Three-dimensional insert molding simulation in injection molding

For the recent years, the insert molding in injection molding has been very popular. Insert molding is a more efficient technology to the assembly of discrete parts. It reduces the assembly and labor costs and increases the design flexibility. Its benefits are over the traditional method, such as soldering, connectors...etc. The different insert parts will cause different effect for injection molding process. The metal inserts are used to increase the performance of drawing heat from the cavity. However, the plastic insert reduce the cooling effects. This paper develops a numerical approach to simulating the mold insert molding in injection-molded part of complex geometry. This developed approach is proved from numerical experiments to be a cost-effective method for true 3D simulation in mold insert molding analysis.
