Using response surface methodology （RSM） and finite element simulation of injection molding, the optimization of injection molding process of the warpage of the mouse cover was solved. Based on the test factors of the injection molding process including the melt temperature, mold temperature,injection time,holding pressure,and the warpage value was the response optimization target, the test planning of injection molding of mouse cover was designed based on central composite design （CCD） ,the response surface model of mouse cover was established between the test factors of injection molding process parameters and response optimization target, the response surface model was also analyzed and evaluated, the optimization ot warpage control process was obtained by Design-Expert, and the accuracy of RSM mold was verified by the simulation test and injection molding,the optimized scheme effectively reduced the warpage of the product, and the product quality was improved. It was indicated that the application of RSM was an effective way to optimize the injection molding process of mouse cover.
