结合正交试验设计和数值模拟，选择模具温度、熔体温度、注射时间、保压压力和保压时间等5个主要工艺参数为设计变量，分别以最小体积收缩率和最小翘曲变形为目标，进行了线槽注射成型工艺参数的单目标优化设计。再利用加权综合评分法，对线槽注射成型工艺参数进行多目标优化设计，获得了兼顾体积收缩率和翘曲变形的工艺参数组合。
結閤正交試驗設計和數值模擬，選擇模具溫度、鎔體溫度、註射時間、保壓壓力和保壓時間等5箇主要工藝參數為設計變量，分彆以最小體積收縮率和最小翹麯變形為目標，進行瞭線槽註射成型工藝參數的單目標優化設計。再利用加權綜閤評分法，對線槽註射成型工藝參數進行多目標優化設計，穫得瞭兼顧體積收縮率和翹麯變形的工藝參數組閤。

The orthogonal experimental method and numerical simulation were applied comprehensively to research the effects of the important process parameters, including mold temperature, melt temperature, injection time, hold pressure and packing time on part＇ s quality. The single-objective optimization of less shrinkage and less warpage were carried out respectively, and the process parameters were optimized. Furthermore, the multi-objective optimization combination giving attention to both shrinkage and warpage was performed and process parameter was obtained by the synthetic weighted mark method.
