The plastic injection molding process was analyzed. The common defects in the process of optimizing design scheme were proposed as well. Based on the rheological theory of polymer material and energy transfer rules, simulation model of the injection molding process was established. Finally, by orthogonal experimental design and variance analysis, multi-objective optimization of plastic molding technology experimental results was analyzed. Results show that the method can effectively achieve injection molding process multi-objective optimization purpose.
