Injection molding process of injected part is simulated under various technological conditions by using analysis software of Moldflow and orthogonal experiment design. The comprehensive evaluation to volume shrinkage ratio change, surface sink index and maximal warp value of the injected part is obtained by means of fuzzy mathematics. From this evaluation,the extent of the overall influence to the process parameters, such as mold temperature, melt temperature, injection time, packing parameters, cooling time,etc, is clarified. Through analyzing the diagrams of influential factors resulted from...
