| Abstract: | The steps of CAE analysis based on Moldflow software for the injection molding ot a thin-walled plastic panel were stated. Based on the simulation of material filling, flowing, cooling and warpage, some key issues like the injection pressure, warping deformation, distribution of weld line and cavitation bubbles were studied. The packing pressure and holding time were thus optimized and the injection defects and plastic deformation were diminished. Finally, the mould design and establishment of technological parameters were finished according to the results of simulation. |
