| 摘 要： | 通过一次因子法确定了Taguchi法的试验因子，采用Taguchi法对试验因子进行权重分析与优化，并进一步研究了注射成型工艺条件对聚丙烯制品光泽度的影响。结果表明，在注射成型过程中，提高熔体温度、模具温度、保压压力及注射速率都有助于提高制品的光泽度，同时也会提高制品的拉伸强度和弯曲强度，但会降低缺口冲击强度。影响聚丙烯制品光泽度的最显著因素是熔体温度。影响因子的权重大小顺序为：熔体温度、模具温度、保压压力、注射速率。

| Abstract: | In order to explore the effect of injection molding parameters on the glossiness of polypropylene parts,Taguchi method was employed to determine the experiment factors and their weighs.It was found that the increase of melt temperature,mold temperature,dwell pressure,and injection rate could increase the glossiness of the parts;meanwhile the tensile and bending strengths would also increase at the cost of notch impact strength.The descending order in weigh of the influence factors was melt temperature,mold ... |
