【摘要】 研究了注塑参数对聚碳酸酯(PC)成型收缩率的影响,从理论上探讨了注塑参数-制品结构-收缩率之间的关系。试验结果表明,对PC成型收缩率影响最大的注塑参数是料温,其次是模具温度、注塑压力和注射速率,而保压时间、冷却时间、预塑速率在实验范围内对PC成型收缩率影响较小。更多还原

【Abstract】 The effects of the injection molding process on the molding shrinkage of Polycarbonates were studied. Based on a lot of experiments, the relationship between the product structure and shrinkage was discussed. The most important parameter effecting the shrinkage of polycarbonate is the melt temperature in the barrel, the second is the mold temperature.更多还原
