The uneven volume shrinkage, molecular orientation and cooling of plastics resulted in the warp of plastic product. Taking the automobile dashboard decorative covers as an example, the warp can be accurately predicted by using of the Moldflow software. The optimized parameters were obtained through analysis of the effects of materials, melt temperature, molding temperature, which was important to the improvement of quality of product and reduction of cost.%以汽车副仪表板装饰盖为例,借助Moldflow软件进行模拟,预测其翘曲变形量,通过分析材料、熔体温度和模具温度对翘曲的影响,从而得到最佳的工艺参数组合,对改善产品质量、降低成本具有重要的指导意义.
