注塑塑料產品噴射問題及解決方案

塑料(liao)(liao)加工噴(pen)(pen)射(she)是指模(mo)制部(bu)件(jian)中的一(yi)種(zhong)變形，當(dang)注(zhu)入熔融(rong)材料(liao)(liao)的初始(shi)“射(she)流(liu)”注(zhu)入模(mo)腔中時，該(gai)模(mo)腔內的空氣在腔體(ti)填充之前開始(shi)凝固。噴(pen)(pen)射(she)通常(chang)表(biao)現為成品部(bu)件(jian)表(biao)面的波浪線，通常(chang)從注(zhu)射(she)的初始(shi)澆口開始(shi)。這(zhe)種(zhong)可見的流(liu)動模(mo)式可能(neng)會導(dao)致部(bu)分軟弱。造成這(zhe)種(zhong)現象的原因是當(dang)熔融(rong)聚合物或其他材料(liao)(liao)在高壓下通過小澆口注(zhu)

注塑模具冷流道系統的理解

塑(su)料(liao)模具廠在注塑(su)加(jia)工塑(su)料(liao)制品中，會有冷(leng)流道(dao)(dao)就是(shi)所謂的“無流道(dao)(dao)”加(jia)工熱塑(su)性(xing)(xing)樹脂的方式，冷(leng)流道(dao)(dao)模具可用來加(jia)工熱固性(xing)(xing)樹脂與彈性(xing)(xing)體材料(liao)。因為這(zhe)類(lei)材料(liao)一旦(dan)產生交聯或 硫(liu)化反應，流道(dao)(dao)系統通(tong)常不(bu)能再(zai)回收加(jia)工，這(zhe)一-點(dian)是(shi)所有里(li)面最為重要(yao)的。冷(leng)流道(dao)(dao)的目的是(shi)將熱固性(xing)(xing)樹脂或彈性(xing)(xing)體材料(liao)的加(jia)工溫(wen)度(du)保持在一定
