用蠟料(liao)(liao)(liao)(liao)做模(mo)樣(yang)(yang)(yang)時(shi)，熔(rong)模(mo)鑄(zhu)(zhu)造(zao)又稱'失蠟鑄(zhu)(zhu)造(zao)'。熔(rong)模(mo)鑄(zhu)(zhu)造(zao)通常是(shi)指在易熔(rong)材料(liao)(liao)(liao)(liao)制(zhi)成(cheng)模(mo)樣(yang)(yang)(yang)，在模(mo)樣(yang)(yang)(yang)表面包覆若干層耐火(huo)材料(liao)(liao)(liao)(liao)制(zhi)成(cheng)型(xing)(xing)殼，再將模(mo)樣(yang)(yang)(yang)熔(rong)化排出型(xing)(xing)殼，從而獲得(de)無分型(xing)(xing)面的鑄(zhu)(zhu)型(xing)(xing)，鋁壓(ya)鑄(zhu)(zhu)，經高溫焙燒(shao)后即可填(tian)砂澆注的鑄(zhu)(zhu)造(zao)方案。由于模(mo)樣(yang)(yang)(yang)廣泛(fan)采用蠟質材料(liao)(liao)(liao)(liao)來制(zhi)造(zao)，故常將熔(rong)模(mo)鑄(zhu)(zhu)造(zao)稱為“失蠟鑄(zhu)(zhu)造(zao)”。

可用熔(rong)模鑄造法生產的(de)合(he)(he)金種(zhong)類有碳素鋼、合(he)(he)金鋼、耐熱(re)合(he)(he)金、不銹鋼、精(jing)密合(he)(he)金、永磁合(he)(he)金、軸(zhou)承合(he)(he)金、銅(tong)合(he)(he)金、鋁合(he)(he)金、鈦(tai)合(he)(he)金和球(qiu)墨鑄鐵(tie)等。

熔(rong)模鑄件(jian)清理的內容主要為

（1）從鑄件上清除型殼；

（2）自澆冒系統上取(qu)下(xia)鑄件；

（3）去除(chu)鑄件(jian)上所粘附的(de)型殼耐火材料；

（4）鑄(zhu)件熱處(chu)理后的清理，如除氧化皮、盡邊和切割澆口殘余等。

熔模鑄造工藝設(she)計(ji)的任(ren)務為

（1）分析鑄件(jian)結構的(de)工藝(yi)性；

（2）選擇(ze)合理的工藝方(fang)案，確定(ding)有關(guan)的鑄造工藝參數，在上述基礎上繪(hui)制鑄件圖；

（3）設計澆(jiao)冒系統(tong)，確定模組結構。

這里要注意的是(shi)，在(zai)考慮上面(mian)三方面(mian)問題時，主要的依據仍(reng)舊是(shi)一(yi)般鑄(zhu)造(zao)過程(cheng)的基本原(yuan)則(ze)，蘇州鋁壓鑄(zhu)哪家(jia)好，尤(you)其是(shi)在(zai)確定工藝(yi)(yi)方案、工藝(yi)(yi)參(can)數時（如鑄(zhu)造(zao)圓角、加(jia)工余量、工藝(yi)(yi)筋等），除了具體數據由(you)于熔(rong)模鑄(zhu)造(zao)的工藝(yi)(yi)特點稍有不同之外，設計(ji)原(yuan)則(ze)與砂型鑄(zhu)造(zao)完(wan)全相同。
