在(zai)工業生產中，離(li)心鑄(zhu)造通常都(dou)通過容積法(fa)和稱重法(fa)得(de)以實現的(de)(de)(de)(de)(de)，這兩種(zhong)防范(fan)不僅操(cao)作過程是(shi)(shi)(shi)不同的(de)(de)(de)(de)(de)，所具備的(de)(de)(de)(de)(de)優(you)勢也(ye)是(shi)(shi)(shi)所區別。到底選(xuan)用(yong)哪(na)一(yi)(yi)種(zhong)更好(hao)?還需(xu)(xu)要進一(yi)(yi)步分析后才知(zhi)道。所謂的(de)(de)(de)(de)(de)容積法(fa)，就是(shi)(shi)(shi)利用(yong)短(duan)流(liu)槽來澆注出相(xiang)應尺寸的(de)(de)(de)(de)(de)鑄(zhu)件(jian)，而對于(yu)澆注液的(de)(de)(de)(de)(de)容積都(dou)是(shi)(shi)(shi)定(ding)量(liang)(liang)的(de)(de)(de)(de)(de)。為了提高定(ding)量(liang)(liang)的(de)(de)(de)(de)(de)精準(zhun)性，在(zai)離(li)心鑄(zhu)造之前都(dou)會設計相(xiang)應的(de)(de)(de)(de)(de)澆包(bao)，它的(de)(de)(de)(de)(de)設計依據(ju)是(shi)(shi)(shi)鑄(zhu)件(jian)重量(liang)(liang)。容積法(fa)進行離(li)心鑄(zhu)造時使用(yong)的(de)(de)(de)(de)(de)這種(zhong)澆包(bao)非常方面，而且還有(you)定(ding)量(liang)(liang)準(zhun)確、重復性好(hao)等優(you)點。而稱重法(fa)是(shi)(shi)(shi)先將需(xu)(xu)要鑄(zhu)造的(de)(de)(de)(de)(de)金屬進行稱量(liang)(liang)，然后一(yi)(yi)次性倒入(ru)并獲得(de)理想的(de)(de)(de)(de)(de)鑄(zhu)件(jian)。這過程中需(xu)(xu)要借助稱量(liang)(liang)設備，才能獲得(de)精準(zhun)的(de)(de)(de)(de)(de)效果。兩種(zhong)方法(fa)雖說都(dou)有(you)不同，但是(shi)(shi)(shi)得(de)到的(de)(de)(de)(de)(de)鑄(zhu)件(jian)還都(dou)是(shi)(shi)(shi)比較(jiao)優(you)質的(de)(de)(de)(de)(de)，所以選(xuan)哪(na)種(zhong)都(dou)可以。
