摘　　要：在注塑机料筒加料段开设轴向和螺旋沟槽进行对比实验。结果表明,开设沟槽可提高塑化产量,螺旋沟槽料筒的塑化产量可明显优于直沟槽料筒;采用大于颗粒直径的沟槽时,略微增大单个沟槽深度和沟槽宽度有利于提高塑化产量,沟槽数目不宜过多;增大沟槽数量和总沟槽宽度未必提高产量。Axial and spiral grooves were compared in solid transportation barrel for improving plasticizing performance in injection machine. Experiments showed that barrel-grooving can enhance the solid transportation efficiency in plasticizing. The spiral groove exhibited better effects than straight axial groove. For barrel groove was larger than solid particle diameter, plasticizing capacity can be increased when single groove width and groove depth were greater. In contrast, more grooves or larger total groove width was not necessary better for raising yield.
