Taking tensile specimen, impact specimen （no gap or without gap ） for example, with warpage and shrinkage as the optimization objective, the mold temperature, melt temperature, injection pressure, injection time, packing pressure, packing time and cooling time were optimized by using the Taguchi, range analysis and variance analysis methods. The optimal injection molding process parameters were determined. A neural network model was developed and then the warpage and shrinkage under changing a single process parameter were predicted by the pr...
