用(yong)(yong)這種方法(fa)鑄出(chu)的(de)(de)(de)(de)銅器既無(wu)范痕，又(you)無(wu)墊片的(de)(de)(de)(de)痕跡，用(yong)(yong)它鑄造(zao)鏤空的(de)(de)(de)(de)器物更佳。中國傳統的(de)(de)(de)(de)熔模鑄造(zao)技(ji)術對(dui)世界的(de)(de)(de)(de)冶金發展有很(hen)(hen)大(da)的(de)(de)(de)(de)影響。現代工(gong)業的(de)(de)(de)(de)熔模精密(mi)鑄造(zao)，鋁(lv)鑄造(zao)工(gong)藝，就是(shi)(shi)從傳統的(de)(de)(de)(de)失蠟(la)法(fa)發展而來的(de)(de)(de)(de)。雖然無(wu)論在所用(yong)(yong)蠟(la)料(liao)、制(zhi)模、造(zao)型材料(liao)、工(gong)藝方法(fa)等方面，它們(men)都有很(hen)(hen)大(da)的(de)(de)(de)(de)不(bu)同，但(dan)是(shi)(shi)它們(men)的(de)(de)(de)(de)工(gong)藝原理是(shi)(shi)一(yi)致(zhi)的(de)(de)(de)(de)。四十年(nian)代中期(qi)，美國工(gong)程師奧斯汀(ting)創立以他(ta)命(ming)名的(de)(de)(de)(de)現代熔模精密(mi)鑄造(zao)技(ji)術時，曾從中國傳統失蠟(la)法(fa)得到啟示。1955年(nian)奧斯汀(ting)實驗(yan)室提出(chu)首i創失蠟(la)法(fa)的(de)(de)(de)(de)呈(cheng)請，日本學者(zhe)鹿取(qu)一(yi)難.根據中國和日本歷是(shi)(shi).上使用(yong)(yong)失蠟(la)法(fa)的(de)(de)(de)(de)事實表(biao)示異議(yi)，鋁(lv)鑄造(zao)廠(chang)，后取(qu)得了(le)勝訴。

低壓鑄造的優勢

      低壓(ya)鑄造在加工(gong)的過程不會出現冒口以及(ji)澆道的情況出現，這樣成品(pin)(pin)的加工(gong)時間可以縮(suo)短很多，整體工(gong)作的效(xiao)率(lv)就會大幅度提高(gao)，產品(pin)(pin)還非(fei)常適合做一(yi)些以及(ji)高(gao)氣密性(xing)的產品(pin)(pin)。

      低壓鑄造在加工(gong)的(de)過程中出現氣孔(kong)或者沙孔(kong)的(de)情況，都(dou)是可(ke)以(yi)進行改善(shan)的(de)，主要是因(yin)為(wei)生(sheng)產工(gong)藝的(de)原因(yin)，可(ke)以(yi)使得鑄件形(xing)成一個(ge)方向(xiang)性的(de)凝固，所以(yi)這(zhe)樣的(de)形(xing)式出現其內部缺陷(xian)的(de)可(ke)能性也會降小。
