Molten Plastic Flow Simulation in the Injection Molding Process

Injection molding is a widely used industrial process, which manufactures plastic parts by forcing molten polymer into a cavity followed by solidification. It should be obvious that the flow analysis in the process is very important to design a solid mold and to determine the operational conditions of an injection-molding machine. To this end we developped the finite element-based flow analysis code named “MOLDIA-F”.In this paper we simulate the molten plastic flow in the process of molding an automobile part by using MOLDIA-F.
