五、 injection molding process 参考
raw materials 干燥：80~85℃烘干3~4h，含水率控制0.05%以内，消除 silver streaks bubbles 。
material 筒 temperature ：190~240℃， in 段215~230℃，喷嘴205~220℃。
mold temperature ：60~80℃， improves 模温优化产品 gloss and 内应力。
process 说明：熔指偏低，相比757 injection molding pressure 偏高，适合 in 厚 wall heat resistant 结构件，不适合 ultra- 薄高速 injection molding 。
六、产品资质说明
Chi Mei (Taiwan) 原装PA-777E原厂正牌， in stock 供应，可配套提供COA出厂报告、MSDS、UL Yellow Card 、RoHS、REACH全套资 material ，外贸报关、产品检测均可使用。
