在生产过程中通常必须将收缩性考虑在内:
1、工件脱模
当工件含有型芯或镂空部分时,随着弹性体的收缩,它会紧紧地裹住模具的这些部位,使工件脱模变得很困难。模具设计、模具表面光洁度以及加工条件都能够缩小这种影响,甚至使自动化脱模也成为可能。
2、模塑条件
模塑条件能显著地影响收缩的程度和本质。若从高应力状态很快地变为低应力状态,收缩的程度将会增加。工件的迅速冷却以及很高的注射速度或压力,也能影响收缩性。
3、设计方面的考虑
考虑到收缩性,模具必须加工得比工件所需的尺寸稍大些。通常,实际收缩值只有等到具体工件成型时才能得知。因此,事先保守一些总是最好的。若有可能,可使用原型模具。

清洗料管 Purge compound |
需使用PP或 PE清洗干净机台螺杆,且把机台射嘴彻底清除干净Please make sure you that you have cleaned the machine screw with PP or PE, and put the machine nozzle thoroughly clean. |
|||||||
着色 Coloring
|
请选择以PE或EVA为基材之色母,切勿使用以PVC为基材者。另外加工时请采用较高的螺杆转速和较高的背压,才能让着色剂达到较好的分散效果Please select color master batch on PE or EVA material with the exception of PVC.Higher screw speed are backpressure are needed for better colorant dispersion. |
