影响聚丙烯模塑件收缩的重要因素包括：

由于聚丙烯材料易于流动，因此它们通常被选择用于大面积模塑件，需要以最小的夹紧力操作。然而，对于许多当前的聚丙烯模塑件，尤其是在需要良好表面光洁度的情况下，通常使用250℃的熔融温度和高包装压力（通常约80 MPa）

Important factors which affect the shrinkage of polypropylene mouldings include:

As a result of the ease of flow of polypropylene materials they are often chosen for large area mouldings where it is desirable to operate with minimum clamp forces. However for many current polypropylene mouldings, especially where good surface finish is required, it is common practice to use melt temperatures of 250oC combined with high packing pressures (typically about 80 MPa).
