Abstract: The outside mold decoration technology was used for mouse shell pad pasting with a polypropylene film. The film thickness distribution and its deforming distribution in X and Y direction was obtained from a simulation with finite element method. The influencing factors of film forming were analyzed. Aimed at the minimum standard deviation of average film thickness and its deforming distribution in X, Y direction, the process parameters were optimized and analyzed through experiment design. The best process parameters were obtained, uniform film thickness distribution and high deformation accuracy were achieved.

Key words: outside mold decoration, simulation, process parameter, optimization
