目前的(de)(de)普通(tong)鑄(zhu)(zhu)型(xing)(xing)(xing)(濕(shi)(shi)型(xing)(xing)(xing))主要(yao)用于生(sheng)(sheng)產(chan)(chan)灰(hui)鑄(zhu)(zhu)鐵,球墨鑄(zhu)(zhu)鐵件(jian),雖然在鑄(zhu)(zhu)鋁(lv)件(jian)生(sheng)(sheng)產(chan)(chan)工(gong)藝方法中,壓鑄(zhu)(zhu),金屬(shu)型(xing)(xing)(xing)鑄(zhu)(zhu)造(zao)(含低壓鑄(zhu)(zhu)造(zao)和重力鑄(zhu)(zhu)造(zao)仍占主導(dao)地(di)位(wei),但(dan)由普通(tong)鑄(zhu)(zhu)型(xing)(xing)(xing)(濕(shi)(shi)型(xing)(xing)(xing))法所生(sheng)(sheng)產(chan)(chan)的(de)(de)鑄(zhu)(zhu)鋁(lv)件(jian)產(chan)(chan)量(liang)在近年來(lai)有所增加.現代的(de)(de)濕(shi)(shi)型(xing)(xing)(xing)砂以膨(peng)(peng)潤(run)土(tu)(tu)(包含系(xi)(xi),系(xi)(xi)及(ji)—活化系(xi)(xi)類)作粘結(jie)劑,適量(liang)添(tian)加淀(dian)粉(fen),煤粉(fen)由于生(sheng)(sheng)產(chan)(chan)鑄(zhu)(zhu)鋁(lv)件(jian)時對潰(kui)散(san)性有較高的(de)(de)要(yao)求(qiu),一般(ban)以系(xi)(xi)膨(peng)(peng)潤(run)土(tu)(tu)為基礎,適量(liang)混(hun)(hun)入系(xi)(xi)膨(peng)(peng)潤(run)土(tu)(tu),或是將3類膨(peng)(peng)潤(run)土(tu)(tu)按(an)比例混(hun)(hun)臺用作粘結(jie)劑.傳統的(de)(de)手工(gong)造(zao)型(xing)(xing)(xing)濕(shi)(shi)型(xing)(xing)(xing)法,生(sheng)(sheng)產(chan)(chan)率低,不(bu)能滿足(zu)現代化大工(gong)業生(sheng)(sheng)產(chan)(chan)的(de)(de)要(yao)求(qiu)。

但現在(zai)(zai)若采用(yong)機(ji)器自動造(zao)型(xing)(xing)生產(chan)(chan)濕(shi)型(xing)(xing)法鑄(zhu)(zhu)鋁(lv)(lv)(lv)件(jian)時(shi),雖初期投資較(jiao)大,但由于(yu)其(qi)運行維持費(fei)用(yong)低,生產(chan)(chan)率(lv)高(gao)及設計更(geng)改較(jiao)為靈活的(de)(de)(de)優點,在(zai)(zai)鑄(zhu)(zhu)鋁(lv)(lv)(lv)件(jian)生產(chan)(chan)中的(de)(de)(de)所占份額趨于(yu)上升，氣(qi)壓造(zao)型(xing)(xing)機(ji)近年(nian)來在(zai)(zai)鑄(zhu)(zhu)型(xing)(xing)的(de)(de)(de)尺寸(cun)精度(du)方面(mian)有(you)極大的(de)(de)(de)提高(gao),有(you)助于(yu)生產(chan)(chan)出復雜(za)程度(du)更(geng)高(gao)的(de)(de)(de)鑄(zhu)(zhu)鋁(lv)(lv)(lv)件(jian)1,2殼(ke)型(xing)(xing)鑄(zhu)(zhu)造(zao)法考慮到(dao)殼(ke)型(xing)(xing)鑄(zhu)(zhu)造(zao)法所生產(chan)(chan)的(de)(de)(de)鑄(zhu)(zhu)件(jian)有(you)較(jiao)高(gao)的(de)(de)(de)尺寸(cun)精度(du),表面(mian)光潔(jie),以及用(yong)作高(gao)壓鑄(zhu)(zhu)造(zao)的(de)(de)(de)型(xing)(xing)芯(xin)時(shi),在(zai)(zai)80的(de)(de)(de)壓力之下其(qi)變形量(liang)和收(shou)縮量(liang)最(zui)小(xiao),在(zai)(zai)鑄(zhu)(zhu)鋁(lv)(lv)(lv)的(de)(de)(de)生產(chan)(chan)過(guo)程中,殼(ke)型(xing)(xing)(芯(xin))的(de)(de)(de)使用(yong)較(jiao)為普遍(bian).但在(zai)(zai)對(dui)所有(you)用(yong)于(yu)鑄(zhu)(zhu)鋁(lv)(lv)(lv)件(jian)生產(chan)(chan)的(de)(de)(de)砂型(xing)(xing),型(xing)(xing)芯(xin)作潰散性評(ping)價(jia)時(shi),殼(ke)型(xing)(xing)覆膜砂的(de)(de)(de)潰散性僅(jin)優于(yu)水玻(bo)璃(li)砂。
