针对用聚碳酸酯/丙烯腈-丁二烯-苯乙烯三元共聚物注塑成型的带孔薄板，在用Moldflow软件模拟注塑成型过程的基础上，利用Taguchi法设计了L25（56）的正交试验，用信噪比衡量制品的熔接痕长度，采用方差分析法分析型腔温度、型芯温度、熔体温度等工艺参数对制品熔接痕长度的影响，并预测了最佳注塑工艺参数。结果表明：在所选择的工艺参数中，对熔接痕长度的影响程度由大到小依次为熔体温度（34.52％）、型腔温度（20.36％）、保压压力（19.43％）、保压时间（13.54％）、型芯温度（6.42％）、注射时间（5.73％）。在最佳工艺参数条件下注塑薄板塑料制件，不仅可以减小熔接痕长度，也有利于提高塑料制件的外观质量。

Simulation production by injection molding process of polycarbonate (PC)/acrylonitrile-butadiene-styrene copolymer (ABS) thin plates with two holes was performed with Moldflow Plastic Insight software. A L25 (56) orthogonal design based on Taguchi was conducted, the weld line length was measured with signal to noise ratio, and the influences of cavity temperature, core temperature, melt temperature, etc. on the weld line length of the plates were analyzed by analysis of variance. The optimal injection molding parameters were predicted. The results show that the significances of each factor selected on the weld line length ranked in descending order are as follows: melt temperature (34.52%), cavity temperature (20.36%), packing pressure (19.43%), packing time (13.54%), core temperature (6.42%) and filling time (5.73%). Optimal process parameters can decrease lengths of weld lines and are favorable for improving the appearance of injection thin plastic plates.
