1，要(yao)(yao)(yao)兼(jian)顧(gu)鑄(zhu)鐵平板鑄(zhu)件的(de)度要(yao)(yao)(yao)求(qiu)和成(cheng)本各(ge)(ge)種(zhong)鑄(zhu)造(zao)方法(fa)所獲得的(de)鑄(zhu)件度不(bu)同，初投資和生(sheng)產率也不(bu)一致，終的(de)經(jing)濟效益也有差異。因(yin)此，要(yao)(yao)(yao)做到多、快、好、省， 應當兼(jian)顧(gu)到各(ge)(ge)個(ge)方面。應對所選用的(de)鑄(zhu)造(zao)方法(fa)進行初步(bu)的(de)成(cheng)本估(gu)算，以確定經(jing)濟效益高又能保(bao)證鑄(zhu)件要(yao)(yao)(yao)求(qiu)的(de)鑄(zhu)造(zao)方法(fa)。
2，鑄(zhu)(zhu)(zhu)(zhu)鐵平(ping)板(ban)鑄(zhu)(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)方(fang)法(fa)應(ying)(ying)(ying)(ying)和(he)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)批(pi)量相(xiang)適(shi)應(ying)(ying)(ying)(ying)，例如砂(sha)型(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)，大(da)(da)(da)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)的(de)(de)(de)(de)工廠應(ying)(ying)(ying)(ying)創造(zao)(zao)(zao)(zao)(zao)(zao)條件(jian)采用技(ji)術(shu)的(de)(de)(de)(de)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)、造(zao)(zao)(zao)(zao)(zao)(zao)芯(xin)方(fang)法(fa)。老式(shi)的(de)(de)(de)(de)震擊式(shi)或震壓式(shi)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)率不夠高(gao)(gao)(gao)，工人勞動(dong)強度大(da)(da)(da)，噪(zao)聲(sheng)大(da)(da)(da)，不適(shi)應(ying)(ying)(ying)(ying)大(da)(da)(da)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)的(de)(de)(de)(de)要求(qiu)(qiu)，應(ying)(ying)(ying)(ying)逐步(bu)加以改(gai)造(zao)(zao)(zao)(zao)(zao)(zao)。對于小型(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)(zhu)件(jian)，可以采用水(shui)平(ping)分型(xing)(xing)(xing)或垂直分型(xing)(xing)(xing)的(de)(de)(de)(de)無箱(xiang)(xiang)高(gao)(gao)(gao)壓造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線、實型(xing)(xing)(xing)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)效率又高(gao)(gao)(gao)，占地面(mian)積也少；對于鑄(zhu)(zhu)(zhu)(zhu)件(jian)可選用各種(zhong)有箱(xiang)(xiang)高(gao)(gao)(gao)壓造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線、氣沖造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)線，以適(shi)應(ying)(ying)(ying)(ying)快速(su)、高(gao)(gao)(gao)度造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)線的(de)(de)(de)(de)要求(qiu)(qiu)，造(zao)(zao)(zao)(zao)(zao)(zao)芯(xin)方(fang)法(fa)可選用：冷(leng)芯(xin)盒、熱芯(xin)盒、殼芯(xin)等(deng)制芯(xin)方(fang)法(fa)。中等(deng)批(pi)量的(de)(de)(de)(de)大(da)(da)(da)型(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)(zhu)件(jian)可以考(kao)慮應(ying)(ying)(ying)(ying)用樹(shu)脂(zhi)自硬(ying)砂(sha)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)和(he)造(zao)(zao)(zao)(zao)(zao)(zao)芯(xin)。單件(jian)小批(pi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)的(de)(de)(de)(de)重型(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)(zhu)件(jian)，手工造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)仍是重要的(de)(de)(de)(de)方(fang)法(fa)，手工造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)能(neng)適(shi)應(ying)(ying)(ying)(ying)各種(zhong)復雜(za)的(de)(de)(de)(de)要求(qiu)(qiu)比較(jiao)靈活，不要求(qiu)(qiu)很(hen)多(duo)工藝裝備。批(pi)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)或長(chang)期生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)的(de)(de)(de)(de)定型(xing)(xing)(xing)產(chan)(chan)(chan)(chan)品(pin)采用多(duo)箱(xiang)(xiang)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)、劈箱(xiang)(xiang)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)法(fa)比較(jiao)適(shi)宜，雖然模(mo)具、砂(sha)箱(xiang)(xiang)等(deng)開始(shi)投(tou)資高(gao)(gao)(gao)，但(dan)可從節約造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)工時、提高(gao)(gao)(gao)產(chan)(chan)(chan)(chan)品(pin)質量方(fang)面(mian)得到補償。低壓鑄(zhu)(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)、壓鑄(zhu)(zhu)(zhu)(zhu)、離心鑄(zhu)(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)等(deng)鑄(zhu)(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)方(fang)法(fa)，因設(she)備和(he)模(mo)具的(de)(de)(de)(de)價(jia)格昂貴，所(suo)以只適(shi)合批(pi)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)。
3，鑄鐵平板造(zao)型方法應適(shi)(shi)合工廠條件(jian)，例如同樣(yang)是生產(chan)(chan)(chan)大型機床床身等(deng)鑄件(jian)，一般采用組芯造(zao)型法，不(bu)(bu)制作(zuo)模樣(yang)和砂箱，在(zai)地(di)坑中組芯；而另外的工廠則采用砂箱造(zao)型法，制作(zuo)模樣(yang)。不(bu)(bu)同的企業生產(chan)(chan)(chan)條件(jian)(包括設備、場地(di)、員工素(su)質(zhi)等(deng))、生產(chan)(chan)(chan)習(xi)慣、所積累的經驗(yan)各不(bu)(bu)一樣(yang)，應該根據這些條件(jian)考慮(lv)適(shi)(shi)合做(zuo)什么產(chan)(chan)(chan)品和不(bu)(bu)適(shi)(shi)合(或不(bu)(bu)能(neng))做(zuo)什么產(chan)(chan)(chan)品。
4，優(you)先采用(yong)(yong)砂(sha)型(xing)(xing)鑄(zhu)(zhu)造(zao)據統計(ji)在全部鑄(zhu)(zhu)鐵平板鑄(zhu)(zhu)件產(chan)(chan)量中，60～70的鑄(zhu)(zhu)件是用(yong)(yong)砂(sha)型(xing)(xing)生產(chan)(chan)的，而且其中70左右(you)是用(yong)(yong)粘土砂(sha)型(xing)(xing)生產(chan)(chan)的。主要原因是砂(sha)型(xing)(xing)鑄(zhu)(zhu)造(zao)較之其它鑄(zhu)(zhu)造(zao)方法成(cheng)本(ben)低、生產(chan)(chan)工藝簡單、生產(chan)(chan)周期(qi)短。
一般來(lai)講，對于中(zhong)、大型(xing)鑄(zhu)件(jian)(jian)，鑄(zhu)鐵件(jian)(jian)可(ke)以(yi)用樹脂自硬砂型(xing)、鑄(zhu)鋼件(jian)(jian)可(ke)以(yi)用水玻璃砂型(xing)來(lai)生(sheng)產，可(ke)以(yi)獲(huo)得尺寸、表面光潔的(de)(de)鑄(zhu)件(jian)(jian)，但成本(ben)較高(gao)。當然(ran)，砂型(xing)鑄(zhu)造(zao)生(sheng)產的(de)(de)鑄(zhu)件(jian)(jian)度、表面光潔度、材質的(de)(de)密度和金相組(zu)織(zhi)、機(ji)械性能等(deng)方面往(wang)(wang)往(wang)(wang)較差，所以(yi)當鑄(zhu)件(jian)(jian)的(de)(de)這些性能要求 高(gao)時，應該采用其它(ta)鑄(zhu)造(zao)方法，例如熔模(失臘)鑄(zhu)造(zao)、壓鑄(zhu)、低(di)壓鑄(zhu)造(zao)等(deng)等(deng)。
