摘　　要：采用Molldflow有限元分析软件,对微塑件的微注射成型过程进行了数值模拟,并采用正交试验设计方法,研究模具温度、熔体温度、保压压力、保压时间等工艺参数对微塑件性能的影响。选择典型微塑件——微泵作为研究对象,用微泵密度作为评价指标,得出不同工艺参数条件下的微泵密度,通过正交试验数值计算方法得到最佳工艺参数组合,为微泵的微注射成型工艺优化提供了一种较为实用的方法。With the finite element analysis software Moldflow, numerical simulation was carried on for micro injection molding process of micro-pump. The mold temperature, melt temperature, packing pressure, and packing time were also analyzed using the orthogonal experiment method. Selected micro-pump as classic micro plastic part and the density as control objectives, the density of micro-pump under different parameters was obtained. Optimized process parameters were got by the orthogonal experiment method. It was provided a more practical approach for process optimization in microiniection molding.
