Abstract: Mouse shell was outside decorated a polypropylene film, and the forming process was simulated with a finite element method. The film thickness distribution, stress distribution, and its deforming distribution in x, y directions were obtained and analyzed. The influence of strain rate was systematically studied. With increasing strain rate, the thickness and stress of the film were increased, the deforming distribution in x, y direction was hardly influenced. And different loading way had a relatively high impact on forming effect.

Key words: strain rate, outside mold decoration, simulation
