1，要(yao)兼顧鑄(zhu)(zhu)(zhu)鐵平板鑄(zhu)(zhu)(zhu)件的(de)(de)度(du)要(yao)求和成本各種鑄(zhu)(zhu)(zhu)造方(fang)法所獲(huo)得(de)的(de)(de)鑄(zhu)(zhu)(zhu)件度(du)不同，初(chu)投資(zi)和生產率也不一致(zhi)，終的(de)(de)經濟效益也有差(cha)異。因此，要(yao)做到多(duo)、快、好、省， 應當兼顧到各個方(fang)面。應對所選用的(de)(de)鑄(zhu)(zhu)(zhu)造方(fang)法進行初(chu)步的(de)(de)成本估算，以確定經濟效益高又能保證鑄(zhu)(zhu)(zhu)件要(yao)求的(de)(de)鑄(zhu)(zhu)(zhu)造方(fang)法。
2，鑄(zhu)(zhu)鐵平板鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)方(fang)(fang)法應(ying)和(he)(he)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)批(pi)(pi)量(liang)相適(shi)應(ying)，例如砂型(xing)(xing)(xing)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)，大(da)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)的(de)工(gong)(gong)(gong)廠應(ying)創造(zao)(zao)(zao)(zao)條件采(cai)用(yong)技術的(de)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)、造(zao)(zao)(zao)(zao)芯(xin)方(fang)(fang)法。老式的(de)震(zhen)擊(ji)式或(huo)震(zhen)壓(ya)式造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)線(xian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)率(lv)不夠高(gao)(gao)(gao)，工(gong)(gong)(gong)人(ren)勞動強度大(da)，噪聲(sheng)大(da)，不適(shi)應(ying)大(da)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)的(de)要(yao)求(qiu)，應(ying)逐步加以(yi)(yi)改造(zao)(zao)(zao)(zao)。對(dui)于小型(xing)(xing)(xing)鑄(zhu)(zhu)件，可以(yi)(yi)采(cai)用(yong)水平分(fen)型(xing)(xing)(xing)或(huo)垂直分(fen)型(xing)(xing)(xing)的(de)無箱(xiang)高(gao)(gao)(gao)壓(ya)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)線(xian)、實型(xing)(xing)(xing)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)效率(lv)又(you)高(gao)(gao)(gao)，占地(di)面積(ji)也少；對(dui)于鑄(zhu)(zhu)件可選(xuan)用(yong)各種(zhong)有箱(xiang)高(gao)(gao)(gao)壓(ya)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)線(xian)、氣沖造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)線(xian)，以(yi)(yi)適(shi)應(ying)快速(su)、高(gao)(gao)(gao)度造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)線(xian)的(de)要(yao)求(qiu)，造(zao)(zao)(zao)(zao)芯(xin)方(fang)(fang)法可選(xuan)用(yong)：冷芯(xin)盒、熱芯(xin)盒、殼芯(xin)等(deng)制芯(xin)方(fang)(fang)法。中等(deng)批(pi)(pi)量(liang)的(de)大(da)型(xing)(xing)(xing)鑄(zhu)(zhu)件可以(yi)(yi)考慮(lv)應(ying)用(yong)樹(shu)脂自硬砂造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)和(he)(he)造(zao)(zao)(zao)(zao)芯(xin)。單件小批(pi)(pi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)的(de)重型(xing)(xing)(xing)鑄(zhu)(zhu)件，手(shou)工(gong)(gong)(gong)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)仍是(shi)重要(yao)的(de)方(fang)(fang)法，手(shou)工(gong)(gong)(gong)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)能(neng)適(shi)應(ying)各種(zhong)復雜的(de)要(yao)求(qiu)比較靈(ling)活，不要(yao)求(qiu)很多工(gong)(gong)(gong)藝裝備(bei)。批(pi)(pi)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)或(huo)長期生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)的(de)定型(xing)(xing)(xing)產(chan)(chan)(chan)(chan)(chan)品采(cai)用(yong)多箱(xiang)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)、劈箱(xiang)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)法比較適(shi)宜，雖然(ran)模具、砂箱(xiang)等(deng)開始(shi)投資高(gao)(gao)(gao)，但可從節約造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)工(gong)(gong)(gong)時、提高(gao)(gao)(gao)產(chan)(chan)(chan)(chan)(chan)品質量(liang)方(fang)(fang)面得到補(bu)償。低壓(ya)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)、壓(ya)鑄(zhu)(zhu)、離心(xin)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)等(deng)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)方(fang)(fang)法，因設備(bei)和(he)(he)模具的(de)價(jia)格(ge)昂貴(gui)，所以(yi)(yi)只適(shi)合批(pi)(pi)量(liang)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)。
3，鑄(zhu)鐵平板造(zao)型(xing)方法應(ying)適合工(gong)廠(chang)條件(jian)(jian)，例(li)如同樣是生(sheng)(sheng)產(chan)大型(xing)機床(chuang)床(chuang)身等鑄(zhu)件(jian)(jian)，一般采用組芯造(zao)型(xing)法，不制作(zuo)模樣和砂(sha)箱(xiang)，在地(di)坑(keng)中組芯；而另外的工(gong)廠(chang)則采用砂(sha)箱(xiang)造(zao)型(xing)法，制作(zuo)模樣。不同的企業生(sheng)(sheng)產(chan)條件(jian)(jian)(包(bao)括設備、場地(di)、員工(gong)素質(zhi)等)、生(sheng)(sheng)產(chan)習(xi)慣、所積累的經驗(yan)各(ge)不一樣，應(ying)該根據這些條件(jian)(jian)考慮適合做什么(me)產(chan)品和不適合(或不能)做什么(me)產(chan)品。
4，優(you)先采(cai)用(yong)砂型鑄(zhu)(zhu)造據統計(ji)在全部鑄(zhu)(zhu)鐵平板鑄(zhu)(zhu)件(jian)產(chan)量中，60～70的鑄(zhu)(zhu)件(jian)是(shi)用(yong)砂型生(sheng)產(chan)的，而且其(qi)中70左右(you)是(shi)用(yong)粘(zhan)土砂型生(sheng)產(chan)的。主要原(yuan)因是(shi)砂型鑄(zhu)(zhu)造較(jiao)之其(qi)它鑄(zhu)(zhu)造方(fang)法成(cheng)本低、生(sheng)產(chan)工藝簡單、生(sheng)產(chan)周期短。
一般來講(jiang)，對于中、大型(xing)鑄(zhu)(zhu)(zhu)件(jian)(jian)，鑄(zhu)(zhu)(zhu)鐵件(jian)(jian)可(ke)以(yi)用(yong)樹脂自(zi)硬砂(sha)型(xing)、鑄(zhu)(zhu)(zhu)鋼件(jian)(jian)可(ke)以(yi)用(yong)水玻璃砂(sha)型(xing)來生產，可(ke)以(yi)獲得尺寸、表面光潔(jie)(jie)的(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)，但成(cheng)本(ben)較高。當(dang)然，砂(sha)型(xing)鑄(zhu)(zhu)(zhu)造(zao)(zao)生產的(de)鑄(zhu)(zhu)(zhu)件(jian)(jian)度、表面光潔(jie)(jie)度、材質的(de)密(mi)度和金相(xiang)組織、機械性能等方面往往較差，所以(yi)當(dang)鑄(zhu)(zhu)(zhu)件(jian)(jian)的(de)這些性能要求 高時(shi)，應該采用(yong)其它鑄(zhu)(zhu)(zhu)造(zao)(zao)方法，例如(ru)熔(rong)模(失臘)鑄(zhu)(zhu)(zhu)造(zao)(zao)、壓鑄(zhu)(zhu)(zhu)、低(di)壓鑄(zhu)(zhu)(zhu)造(zao)(zao)等等。
