| Abstract: | From three aspects including numerical calculating theory, mechanical theory and accumulated errors of CAE in injection molding, the authors elaborate the main reasons of errors systematically and comprehensively during the finite element numerical simulating the warpage of injection molded parts. The reasonable and efficient improvements can be done to get more accurate simulated results. |
