style="text-indent:25px">注塑塑料模具廠能做雙色模嗎？雙色模具是由過去的包膠模具發(fā)展進(jìn)化而來的。以前是先用啤ABS或PC等硬膠的成品放到另一套啤軟膠如PVC或PU等模具上再次注塑而成。這種注塑形式俗稱套啤，也叫包膠。后來幾經(jīng)改良漸漸進(jìn)步到了現(xiàn)在的雙色注塑。一般注塑塑料模具廠都可以做。雙色注塑是由兩套互相能套合的模具在同一臺(tái)注塑機(jī)上旋轉(zhuǎn)，一套注硬膠，另一套注軟膠，同時(shí)注塑完成。雙色模具與通常的單色模具沒有太大的差異，所有做普通模具的都能做雙色模具，它的加工工藝都是類同的，只是結(jié)構(gòu)設(shè)計(jì)上復(fù)雜一點(diǎn)而已。所以注塑塑料模具廠是可以做雙色模的，但普通的單色注塑機(jī)就不能做雙色注塑。雙色模具只能由特制的雙色注塑機(jī)啤貨。目前雙色模具和雙色注塑還是初級(jí)階段。隨著人們對產(chǎn)品外觀和手感的要求越來越高，注塑塑料模具廠的雙色注塑大有前途！合肥導(dǎo)線注塑模具定制廠家注塑成型加工過程中是一個(gè)涉及模具設(shè)計(jì)、模具制造、原材料特性等多方面因素。</p><div

style="text-indent:25px">注塑壓力是由注塑系統(tǒng)的液壓系統(tǒng)提供的。液壓缸的壓力通過注塑機(jī)螺桿傳遞到塑料熔體上，塑料熔體在壓力的推動(dòng)下，經(jīng)注塑機(jī)的噴嘴進(jìn)入模具的豎流道（對于部分模具來說也是主流道）、主流道、分流道，并經(jīng)澆口進(jìn)入模具型腔，這個(gè)過程即為注塑過程，或者稱之為填充過程。壓力的存在是為了克服熔體流動(dòng)過程中的阻力，或者反過來說，流動(dòng)過程中存在的阻力需要注塑機(jī)的壓力來抵消，以保證填充過程順利進(jìn)行。在注塑過程中，注塑機(jī)噴嘴處的壓力較高，以克服熔體全程中的流動(dòng)阻力。其后，壓力沿著流動(dòng)長度往熔體較前端波前處逐步降低，如果模腔內(nèi)部排氣良好，則熔體前端然后的壓力就是大氣壓。影響熔體填充壓力的因素很多，概括起來有3類：⑴材料因素，如塑料的類型、粘度等；⑵結(jié)構(gòu)性因素，如澆注系統(tǒng)的類型、數(shù)目和位置，模具的型腔形狀以及制品的厚度等；⑶成型的工藝要素。</p><p

style="text-indent:25px">注塑模具溫度對塑件的影響：提高模具溫度可以改善塑件的表面質(zhì)量。模具溫度的確定注射成型工藝過程中，模具溫度直接影響到塑料的充模、塑件的定型、模塑周期和塑件質(zhì)量。而模具溫度的高低取決于塑料結(jié)晶性、塑件尺寸與結(jié)構(gòu)、性能要求以及其它工藝條件如熔料溫度、注射速度、注射壓力和模塑周期等。對于無定型聚合物，其熔體在注入模腔后隨著溫度的降低而固化，但并不發(fā)生相的轉(zhuǎn)變，模溫主要影響熔體的粘度，即充模速率。因此，對于熔融粘度較低和中等的無定型塑料如聚苯乙烯、醋酸纖維素等，采用較低的模具溫度可以縮短冷卻時(shí)間。注塑pc產(chǎn)品在成形生產(chǎn)加工以前需開展充足的干躁解決。瓶胚注塑模具定做廠家</p><p
