PP特性————————
加工工艺
干燥处理：如果储存适当则不需要干燥处理。
熔化温度：220~275C，注意不要超过275C。
模具温度：40~80C，建议使用50C。结晶程度主要由模具温度决定。
注射压力：可大到1800bar。
注射速度：通常，使用高速注塑可以使内部压力减小到最小。如果制品表面出现了缺陷，那么应使用较高温度下的低速注塑。
流道和浇口：对于冷流道，典型的流道直径范围是4~7mm。建议使用通体为圆形的注入口和流道。所有类型的浇口都可以使用。典型的浇口直径范围是1~1.5mm，但也可以使用小到0.7mm的浇口。 对于边缘浇口，最小的浇口深度应为壁厚的一半；最小的浇口宽度应至少为壁厚的两倍。PP材料完全可以使用热流道系统。
成型特性
1.结晶料，吸湿性小，易发生融体破裂，长期与热金属接触易分解。
2.流动性好，但收缩范围及收缩值大，易发生缩孔，凹痕，变形。
3.冷却速度快，浇注系统及冷却系统应缓慢散热，并注意控制成型温度.料温低温高压时容易取向，模具温度低于50度时，塑件不光滑，易产生熔接不良，流痕，90度以上易发生翘曲变形。
4.塑料壁厚须均匀，避免缺胶，尖角，以防应力集中。
