摘　　要：以企业实际缺陷制品为研究基础,通过分析实际成型工艺条件对模流分析精度的影响,强化模流分析工艺条件的输入输出,从而控制实际成型时的扰动误差。首先运用UDE试验设计找到最佳工艺参数组合,进而通过对Ram曲线拟合和保压曲线优化,得到最优的体积收缩率分布。结果表明,差异性分析有助于指导实际生产,改善了企业该产品缩痕缺陷并成功生产。The study was based on the actual defect product, and to analyze the actual molding processing conditions which impacted on the accuracy of Moldflow analysis, enhance the input and output of the processing conditions in Moldflow, thereby controlling the actual molding＇s disturbance error. Firstly, UDE experimental design was used to find the best combination of processing parameters then optimized the distribution of volume shrinkage through fitting the Ram curve and packing curve＇s optimization. The results showed that the difference analysis was to help to guide the actual production, which improved the defect product with sink marks for the enterprises and had successfully production.
