Design of Plastic Injection Mold Based on CAE Technique

Flow and heat transfer are two very complex physical processes in plastic injection molding. Using CAE technique, the mold design can be analyzed and simulated in computer to replace the actual mold trial-and-error and potential defect can be predicted and corrected before mold is made. Theories of numerical analysis are introduced and how to use the CAE results to optimize injection mold delivery and cooling system design with some typical examples is illustrated.
