透明易拉罐的三種制作方式:
(1)是較專業(ye)用(yong)途之(zhi)(zhi)(zhi)射出吹(chui)瓶(ping),這部分(fen)很像一(yi)般之(zhi)(zhi)(zhi)射出成(cheng)型(xing),也是透(tou)過(guo)腔體內(nei)(nei)螺桿之(zhi)(zhi)(zhi)轉動(dong)控制及外(wai)部加(jia)熱(re)器之(zhi)(zhi)(zhi)配合使用(yong),將塑料原料從(cong)料斗進(jin)(jin)料經(jing)混練壓(ya)縮而(er)后趁熱(re)將軟(ruan)化熔融之(zhi)(zhi)(zhi)塑料射出進(jin)(jin)入一(yi)模型(xing)內(nei)(nei)而(er)形(xing)成(cheng)有螺牙之(zhi)(zhi)(zhi)初胚,然后經(jing)過(guo)一(yi)180度之(zhi)(zhi)(zhi)轉動(dong)機構將此(ci)毛胚傳送至另一(yi)頭(tou)事先規劃好形(xing)狀之(zhi)(zhi)(zhi)中空瓶(ping)模內(nei)(nei),透(tou)過(guo)高壓(ya)之(zhi)(zhi)(zhi)空氣將此(ci)初胚吹(chui)脹成(cheng)模具(ju)內(nei)(nei)壁之(zhi)(zhi)(zhi)形(xing)狀,如嬰兒喂(wei)乳用(yong)之(zhi)(zhi)(zhi)乳瓶(ping),化妝品護手膏之(zhi)(zhi)(zhi)專業(ye)瓶(ping)子。
(2)是(shi)射出(chu)(chu)(chu)(chu)拉(la)胚吹(chui)(chui)出(chu)(chu)(chu)(chu)成(cheng)形,不(bu)同之(zhi)(zhi)(zhi)地方在(zai)(zai)于(yu)其在(zai)(zai)吹(chui)(chui)出(chu)(chu)(chu)(chu)成(cheng)形前會(hui)在(zai)(zai)經(jing)(jing)一(yi)(yi)(yi)道拉(la)胚之(zhi)(zhi)(zhi)步(bu)驟,因(yin)此可以吹(chui)(chui)出(chu)(chu)(chu)(chu)較(jiao)薄(bo)又厚薄(bo)均勻之(zhi)(zhi)(zhi)瓶(ping)(ping)子如裝(zhuang)汽水之(zhi)(zhi)(zhi)寶(bao)特瓶(ping)(ping)押(ya)出(chu)(chu)(chu)(chu)吹(chui)(chui)瓶(ping)(ping)和射出(chu)(chu)(chu)(chu)吹(chui)(chui)瓶(ping)(ping)之(zhi)(zhi)(zhi)成(cheng)品(pin)(pin)較(jiao)主要之(zhi)(zhi)(zhi)不(bu)同在(zai)(zai)于(yu)瓶(ping)(ping)口螺牙之(zhi)(zhi)(zhi)成(cheng)型(xing),前者系經(jing)(jing)吹(chui)(chui)氣(qi)成(cheng)型(xing)因(yin)此內(nei)壁(bi)會(hui)隨著(zhu)模(mo)具之(zhi)(zhi)(zhi)凹凸而起伏,后者則(ze)(ze)為(wei)射出(chu)(chu)(chu)(chu)成(cheng)型(xing),因(yin)此內(nei)壁(bi)平(ping)滑光(guang)溜,另外(wai)則(ze)(ze)在(zai)(zai)于(yu)瓶(ping)(ping)子底部,若是(shi)射出(chu)(chu)(chu)(chu)吹(chui)(chui)瓶(ping)(ping)之(zhi)(zhi)(zhi)成(cheng)品(pin)(pin)多(duo)多(duo)少少會(hui)有(you)一(yi)(yi)(yi)射出(chu)(chu)(chu)(chu)灌注(zhu)點之(zhi)(zhi)(zhi)痕跡,押(ya)出(chu)(chu)(chu)(chu)吹(chui)(chui)瓶(ping)(ping)則(ze)(ze)會(hui)有(you)模(mo)具合模(mo)線之(zhi)(zhi)(zhi)存在(zai)(zai),射出(chu)(chu)(chu)(chu)吹(chui)(chui)瓶(ping)(ping)因(yin)瓶(ping)(ping)內(nei)平(ping)滑比(bi)較(jiao)不(bu)易(yi)藏污納垢,因(yin)此很多(duo)用(yong)途大多(duo)使用(yong)在(zai)(zai)需(xu)時常清潔(jie)處理之(zhi)(zhi)(zhi)地方如前所提及之(zhi)(zhi)(zhi)乳瓶(ping)(ping),或(huo)因(yin)押(ya)出(chu)(chu)(chu)(chu)吹(chui)(chui)瓶(ping)(ping)之(zhi)(zhi)(zhi)瓶(ping)(ping)口較(jiao)鋒利深(shen)怕(pa)使用(yong)時會(hui)割傷手部,一(yi)(yi)(yi)些(xie)偏重穩(wen)定(ding)性使用(yong)的化妝品(pin)(pin)瓶(ping)(ping)子。
(3)是比(bi)較常用的(de)較為傳(chuan)統的(de)押(ya)出(chu)吹(chui)瓶方法,是將塑(su)料(liao)(liao)的(de)原料(liao)(liao)在腔體內通過(guo)螺桿配合外(wai)部加熱器(qi)的(de)使用,從(cong)事(shi)進料(liao)(liao)混練壓縮而(er)后趁熱將軟化熔融之(zhi)塑(su)料(liao)(liao)押(ya)出(chu)成中(zhong)空管狀(zhuang),配合模(mo)具(ju)(ju)傳(chuan)動機(ji)構之(zhi)夾(jia)取,將由上押(ya)出(chu)垂下之(zhi)管狀(zhuang)體夾(jia)在預先設計好造型之(zhi)中(zhong)空模(mo)具(ju)(ju)內,透(tou)過(guo)吹(chui)針內之(zhi)高壓空氣將軟化之(zhi)塑(su)料(liao)(liao)吹(chui)脹至模(mo)具(ju)(ju)內壁,就可依模(mo)具(ju)(ju)事(shi)先規劃好之(zhi)形狀(zhuang)成型,然后再透(tou)過(guo)輔助(zhu)之(zhi)切斷機(ji)構從(cong)模(mo)具(ju)(ju)外(wai)將瓶口多余之(zhi)部位(wei)去除(chu),生產速度快(kuai)是其較大的(de)特點。
