鑄造(zao)工藝可分為(wei)三個基本部分，即鑄造(zao)金屬準備(bei)、鑄型準備(bei)和(he)鑄件(jian)處理。 鑄造(zao)金屬是(shi)指(zhi)鑄造(zao)生產(chan)中(zhong)用于澆注鑄件(jian)的(de)(de)金屬材料(liao)(liao)。金屬熔煉不(bu)(bu)僅僅是(shi)單純(chun)的(de)(de)熔化，還包括(kuo)冶煉過程，使澆進(jin)鑄型的(de)(de)金屬，在(zai)(zai)(zai)溫度、化學(xue)成(cheng)分和(he)純(chun)凈度方(fang)面都符合預(yu)期要求。硅溶(rong)膠精密鑄造(zao)在(zai)(zai)(zai)陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)料(liao)(liao)的(de)(de)應用，現如(ru)今，陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)料(liao)(liao)一般都是(shi)用在(zai)(zai)(zai)炊具生產(chan)，但其實它(ta)的(de)(de)適用范圍廣(guang)泛，而且它(ta)的(de)(de)前景也是(shi)十分廣(guang)闊的(de)(de)。陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)料(liao)(liao)的(de)(de)硅溶(rong)膠含(han)量是(shi)非(fei)常高的(de)(de)，陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)層不(bu)(bu)可燃，也無煙(yan)，而且與同(tong)類(lei)材料(liao)(liao)比，硅溶(rong)膠為(wei)原(yuan)材料(liao)(liao)的(de)(de)陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)料(liao)(liao)更為(wei)環(huan)保。在(zai)(zai)(zai)高溫條件(jian)下，不(bu)(bu)會釋放(fang)有(you)(you)害氣(qi)體，在(zai)(zai)(zai)發(fa)生火災時有(you)(you)很(hen)大的(de)(de)安全性(xing)。陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)料(liao)(liao)用在(zai)(zai)(zai)地(di)鐵中(zhong)幾率(lv)是(shi)是(shi)很(hen)大的(de)(de)，目前在(zai)(zai)(zai)地(di)鐵站內的(de)(de)鋁制幕墻板和(he)列車車頭的(de)(de)內部涂(tu)(tu)(tu)層是(shi)已經開始使用的(de)(de)了。在(zai)(zai)(zai)以(yi)后(hou)的(de)(de)地(di)鐵的(de)(de)建設中(zhong)，陶(tao)(tao)瓷(ci)涂(tu)(tu)(tu)料(liao)(liao)的(de)(de)使用將(jiang)會得到很(hen)大普(pu)及。
