| Abstract: | Taking a certain type of instrument display shell as the study object, the CAE and DOE technologies are used to perform numerical simulation test on its warpage defects appearing in the process of injection molding. The effect of process parameters on warpage, including melt temperature, mold temperature, holding pressure and holding time, is studied; according to the test data, the range analysis is done to optimize the process parameters; the optimal process parameters are obtained finally. The process parameters can improve molding quality of plastic parts and production efficiency, shorten test cycle, and provide reference for the actual production of thin wall plastic parts. |

| Keywords: | thin-wall plastic part instrument shell injection molding warpage |
