注(zhu)塑(su)件注(zhu)塑(su)加(jia)工(gong)(gong)(gong)(gong)流程是一種復雜(za)的加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝，可(ke)以用來制(zhi)造各種復雜(za)的結構和形狀(zhuang)的零(ling)件。它是一種熱塑(su)性(xing)塑(su)料加(jia)工(gong)(gong)(gong)(gong)工(gong)(gong)(gong)(gong)藝，通(tong)過將熔融的塑(su)料液體壓入模具中，以固定形狀(zhuang)冷卻固化成(cheng)型，以達(da)到制(zhi)造零(ling)件的目的。

注(zhu)(zhu)塑件注(zhu)(zhu)塑加工流(liu)程主要包括料斗裝料、模具加熱、塑料熔融、注(zhu)(zhu)射(she)成型、模具冷(leng)卻、產(chan)品取(qu)出等步驟。

注(zhu)塑(su)件(jian)注(zhu)塑(su)加工成(cheng)(cheng)型的(de)(de)成(cheng)(cheng)型周(zhou)期由合(he)模時(shi)間(jian)(jian)(jian)、充填時(shi)間(jian)(jian)(jian)、保壓時(shi)間(jian)(jian)(jian)、冷(leng)(leng)卻(que)時(shi)間(jian)(jian)(jian)及脫(tuo)模時(shi)間(jian)(jian)(jian)組成(cheng)(cheng)。其中以(yi)(yi)冷(leng)(leng)卻(que)時(shi)間(jian)(jian)(jian)所占(zhan)比(bi)重比(bi)較大，大約為70%——80%。因(yin)此冷(leng)(leng)卻(que)時(shi)間(jian)(jian)(jian)將直接影響塑(su)料(liao)制品(pin)(pin)成(cheng)(cheng)型周(zhou)期長短及產量(liang)大小。脫(tuo)模階段塑(su)料(liao)制品(pin)(pin)溫度應(ying)冷(leng)(leng)卻(que)至(zhi)低于塑(su)料(liao)制品(pin)(pin)的(de)(de)熱(re)變形溫度，以(yi)(yi)防止塑(su)料(liao)制品(pin)(pin)因(yin)殘余(yu)應(ying)力(li)導(dao)致(zhi)的(de)(de)松(song)弛現象或脫(tuo)模外力(li)所造成(cheng)(cheng)的(de)(de)翹(qiao)曲及變形。
