| 摘 要： | 质量控制是注塑过程控制研究的重要内容，而保压过程是决定最终制品质量的一个重要阶段。在大量实验结果的基础上探讨了最优保压压力曲线的设定。实验结果表明，递减型线性保压压力曲线有利于减小模腔压力差和制品粗糙度，而递增型保压曲线则可能加大制品粗糙度。另外，阶跃型保压曲线与线性保压曲线相比，没有任何质量优势，还可能造成熔体倒流。

| Abstract: | Packing stage plays an important role in injection molded part quality.The optimal packing profile is experimemtally studied to achieve most uniform part quality.The deareasing ramp profile of the packing pressure is found to be beneficial to reduce the cavity pressure difference and improve the part evenness.The decreasing step change profile,though recommended by other researchers,is experimentally demonstrated to be inferior to the ramp one. |
