適用(yong)于制造簡(jian)單的(de)(de)片(pian)狀(zhuang)、板狀(zhuang)制品。它是將混煉膠(jiao)(jiao)(jiao)(jiao)(jiao)通過壓延機壓制成(cheng)一(yi)定(ding)形(xing)狀(zhuang)、一(yi)定(ding)尺(chi)寸的(de)(de)膠(jiao)(jiao)(jiao)(jiao)(jiao)片(pian)的(de)(de)方法叫壓延成(cheng)型(xing)。 有些(xie)橡膠(jiao)(jiao)(jiao)(jiao)(jiao)制品?如輪(lun)胎、膠(jiao)(jiao)(jiao)(jiao)(jiao)布、膠(jiao)(jiao)(jiao)(jiao)(jiao)管等所用(yong)紡織纖(xian)維材(cai)料必須涂上(shang)一(yi)層薄膠(jiao)(jiao)(jiao)(jiao)(jiao)在纖(xian)維上(shang)涂膠(jiao)(jiao)(jiao)(jiao)(jiao)也(ye)叫貼膠(jiao)(jiao)(jiao)(jiao)(jiao)或擦膠(jiao)(jiao)(jiao)(jiao)(jiao)??涂膠(jiao)(jiao)(jiao)(jiao)(jiao)工序一(yi)般也(ye)在壓延機上(shang)完成(cheng)。纖(xian)維材(cai)料在壓延前需要進(jin)行(xing)烘干和浸膠(jiao)(jiao)(jiao)(jiao)(jiao)烘干的(de)(de)目的(de)(de)是為了減少纖(xian)維材(cai)料的(de)(de)含水(shui)量以免水(shui)分(fen)蒸(zheng)發起泡(pao)?和提(ti)高(gao)纖(xian)維材(cai)料的(de)(de)溫度以保證壓延工藝的(de)(de)質量。浸膠(jiao)(jiao)(jiao)(jiao)(jiao)是掛(gua)膠(jiao)(jiao)(jiao)(jiao)(jiao)前的(de)(de)必要工序目的(de)(de)是為了提(ti)高(gao)纖(xian)維材(cai)料與膠(jiao)(jiao)(jiao)(jiao)(jiao)料的(de)(de)結合性能。

橡(xiang)(xiang)膠制(zhi)品(pin)種(zhong)類繁多，但生產工藝(yi)(yi)過(guo)程卻基本相同。以(yi)一般固體橡(xiang)(xiang)膠——生膠為原(yuan)料(liao)的(de)橡(xiang)(xiang)膠制(zhi)品(pin)的(de)基本工藝(yi)(yi)過(guo)程包括：塑煉、混煉、壓延、壓出(chu)、成(cheng)(cheng)型(xing)、硫化6個(ge)基本工序。當(dang)然，橡(xiang)(xiang)膠螺絲，原(yuan)材料(liao)準備(bei)、成(cheng)(cheng)品(pin)整理(li)、檢驗包裝等基本工序也(ye)少(shao)不了。 橡(xiang)(xiang)膠的(de)加工工藝(yi)(yi)過(guo)程主要是解決塑性(xing)(xing)和彈性(xing)(xing)性(xing)(xing)能這個(ge)矛盾的(de)過(guo)程。通過(guo)各(ge)種(zhong)工藝(yi)(yi)手段，使得彈性(xing)(xing)的(de)橡(xiang)(xiang)膠變(bian)成(cheng)(cheng)具有塑性(xing)(xing)的(de)塑煉膠，再(zai)加入各(ge)種(zhong)配合劑制(zhi)成(cheng)(cheng)半成(cheng)(cheng)品(pin)，然后(hou)通過(guo)硫化使具有塑性(xing)(xing)的(de)半成(cheng)(cheng)品(pin)又變(bian)成(cheng)(cheng)彈性(xing)(xing)高、物理(li)機械(xie)性(xing)(xing)能好的(de)橡(xiang)(xiang)膠制(zhi)品(pin)。
