TPR、TPR脚轮料、惠州TPR胶料供应商(智能穿戴) TPR材料RN35D-01
TPE制品加工色差是注塑中常见的缺陷, 因配套件颜色差别造成注塑机成批报废的情况并不小见。色差影响因素众多,涉及原料树脂、色母、色母同原料的混合、注塑工艺、注塑机、模具等,正因为牵涉面广泛,因此色差控制技术同时也是注塑中公认较难掌握技术之一。在实际的生产过程中我们一般从以下六个方面来进行色差的控制。
1.消除注塑机及模具因素的影响
要选择与注塑主品容量相当的注塑机,如果注塑机存在物料死角等问题,最好更换设备。对于模具浇注系统、排气槽等造成色差的,可通过相应部分模具的维修模来解决。必须首先解决好注塑机及模具问题才可以组织生产,以削减问题的复杂性。

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. |
