透明塑(su)料(liao)由于(yu)透光率要(yao)高(gao)，必然(ran)要(yao)求(qiu)塑(su)料(liao)制品表面質量要(yao)求(qiu)嚴格，不能有任何(he)斑紋(wen)、氣孔、泛白、霧(wu)暈、黑點(dian)、變(bian)色、光澤不佳等缺陷(xian)，因(yin)而在整(zheng)個注(zhu)塑(su)過(guo)程(cheng)對原(yuan)料(liao)、設備、模(mo)具(ju)、甚(shen)至產(chan)品的設計，都要(yao)十...

塑料材(cai)料性能的(de)(de)(de)復雜性決定(ding)了注射成型過程的(de)(de)(de)復雜性。而塑料材(cai)料的(de)(de)(de)性能又因(yin)品種(zhong)不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)、牌號(hao)不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)、生(sheng)產廠家不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)、甚至(zhi)批次不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)而差(cha)異較大。不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)的(de)(de)(de)性能參(can)數可能導致完全不(bu)(bu)(bu)同(tong)(tong)(tong)(tong)的(de)(de)(de)成型結果(guo)。...
