Abstract: An injection mould for covers of electric kettle was developed based on CAE technology in this paper. Two gate locations were determined by best gate location analysis. The optimal processing parameters were determined by the molding windows analysis as mold temperature 45℃, melt temperature 235℃, and injection time 1 s. The filling quality of the cover was examined after the filling process so as to adjust the injection pressure and the clamp force. The layout of cooling system was also optimized. Practical injection proved that CAE technology can be used to ensure the reasonable and efficiency of mold design, and high quality products can be obtained.
