Abstract: The injection molding process with different wall thickness may create the obvious cavitation flaw. So carried on the kinetic simulation of filling injection using plastic advisor with Pro/E software, and discussed the melt flows in the mould. Research the cavitation defect of the jubilance toy's part with different wall thickness, and forecast reasonably position and quantity of the cavitation, and through the change of formation technological parameter, obtained the relatively good formation technological combination, achieved the reduced flaw quantity. Which provided the theory basis to study and removes the product flaw, provided reference for the discussion injection CAE, indicated it had great singlenificance for the visualization experimental study.

Abstract: Obtains the best deep product for the choice suitable blank dimensions, process structure and profile of the oil tank part has been analyzed, and has carried on numerical simulation target-oriented of the box bulkhead by the MSC.SuperForm software. Has studied the influence on blank with different radius of curvature and length to equivalent strain and drawing strength of 304 stainless steels, the optimization obtained the best size, voided flaw arousing because of blank size
