1.TPE产品包胶部位结构的设计,尽量做到尺寸圆滑,无明显的棱角,增大TPE与尼龙硬胶接触的紧密性。
2.足够的注塑温度。TPE包胶尼龙,塑伯建议TPE注塑温度要在190摄氏度以上为佳,不超过240度都可。特别是要获得真包胶的效果,因为尼龙的软化温度在250-260度,在保证TPE不降解的前提下,TPE与尼龙软化温度越接近,包胶效果越好。
3.对新开的模具,需注意模具进浇口及流道的设计。因TPE包胶层一般比较薄,厚度在1-2mm为常见,而包胶层尺寸一般在几十甚至上百mm,因此必须保证TPE软胶能充满模腔,不缺胶,不批缝,保证TPE与尼龙的粘合性。
4.在尼龙骨架件无关重要的位置上开些小孔,或制造些不光滑的表面,加大TPE与尼龙的接触面积,使TPE软胶通过小孔嵌入到尼龙骨架材料内,起到箍嵌效果。实际上是真包与假包效果并用。
