Taking flange product as the sample, finite element analysis software Moldflow was used to research the main reason about shrinkage and warpage. According to four key parameters about injection process, the orthogonal experiment method was chosen to design the experimental method. The Moldflow software was used to simulate the experiment with each kind group of process parameters. The experiment data with R square and S/N method was analyzed to get the best process parameters group. And the optimal combination of process parameters were obtained. According to this experiment, the temperature o...
