1，要(yao)(yao)兼(jian)顧鑄鐵平板鑄件(jian)的度(du)要(yao)(yao)求和成本各種鑄造方(fang)法所(suo)獲得的鑄件(jian)度(du)不同，初(chu)投(tou)資和生產(chan)率也不一致，終(zhong)的經濟(ji)效(xiao)益也有差(cha)異。因(yin)此，要(yao)(yao)做到(dao)多(duo)、快、好、省， 應當兼(jian)顧到(dao)各個方(fang)面。應對(dui)所(suo)選用的鑄造方(fang)法進(jin)行初(chu)步的成本估算，以確定經濟(ji)效(xiao)益高又能保證鑄件(jian)要(yao)(yao)求的鑄造方(fang)法。
2，鑄(zhu)(zhu)(zhu)鐵平板鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)方法(fa)(fa)應(ying)(ying)(ying)和生(sheng)產(chan)(chan)(chan)批(pi)量(liang)相(xiang)適應(ying)(ying)(ying)，例如砂(sha)型(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)，大(da)(da)量(liang)生(sheng)產(chan)(chan)(chan)的(de)(de)工(gong)(gong)(gong)廠應(ying)(ying)(ying)創(chuang)造(zao)(zao)(zao)(zao)(zao)(zao)條(tiao)件(jian)采(cai)用(yong)技術的(de)(de)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)、造(zao)(zao)(zao)(zao)(zao)(zao)芯(xin)方法(fa)(fa)。老式的(de)(de)震(zhen)擊(ji)式或震(zhen)壓式造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)機(ji)生(sheng)產(chan)(chan)(chan)線生(sheng)產(chan)(chan)(chan)率不(bu)夠(gou)高，工(gong)(gong)(gong)人勞動強(qiang)度大(da)(da)，噪聲大(da)(da)，不(bu)適應(ying)(ying)(ying)大(da)(da)量(liang)生(sheng)產(chan)(chan)(chan)的(de)(de)要(yao)(yao)求，應(ying)(ying)(ying)逐步加以改造(zao)(zao)(zao)(zao)(zao)(zao)。對(dui)于小(xiao)型(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)件(jian)，可以采(cai)用(yong)水平分(fen)型(xing)(xing)(xing)(xing)或垂直分(fen)型(xing)(xing)(xing)(xing)的(de)(de)無箱(xiang)高壓造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)機(ji)生(sheng)產(chan)(chan)(chan)線、實型(xing)(xing)(xing)(xing)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)生(sheng)產(chan)(chan)(chan)效率又高，占地面(mian)積也(ye)少；對(dui)于鑄(zhu)(zhu)(zhu)件(jian)可選(xuan)用(yong)各種有箱(xiang)高壓造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)機(ji)生(sheng)產(chan)(chan)(chan)線、氣沖造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)線，以適應(ying)(ying)(ying)快速、高度造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)生(sheng)產(chan)(chan)(chan)線的(de)(de)要(yao)(yao)求，造(zao)(zao)(zao)(zao)(zao)(zao)芯(xin)方法(fa)(fa)可選(xuan)用(yong)：冷(leng)芯(xin)盒(he)、熱(re)芯(xin)盒(he)、殼(ke)芯(xin)等(deng)制(zhi)芯(xin)方法(fa)(fa)。中等(deng)批(pi)量(liang)的(de)(de)大(da)(da)型(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)件(jian)可以考慮(lv)應(ying)(ying)(ying)用(yong)樹脂自硬(ying)砂(sha)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)和造(zao)(zao)(zao)(zao)(zao)(zao)芯(xin)。單(dan)件(jian)小(xiao)批(pi)生(sheng)產(chan)(chan)(chan)的(de)(de)重型(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)件(jian)，手工(gong)(gong)(gong)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)仍是重要(yao)(yao)的(de)(de)方法(fa)(fa)，手工(gong)(gong)(gong)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)能適應(ying)(ying)(ying)各種復雜(za)的(de)(de)要(yao)(yao)求比(bi)較靈活，不(bu)要(yao)(yao)求很多工(gong)(gong)(gong)藝裝備。批(pi)量(liang)生(sheng)產(chan)(chan)(chan)或長期(qi)生(sheng)產(chan)(chan)(chan)的(de)(de)定型(xing)(xing)(xing)(xing)產(chan)(chan)(chan)品采(cai)用(yong)多箱(xiang)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)、劈(pi)箱(xiang)造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)法(fa)(fa)比(bi)較適宜，雖然(ran)模具、砂(sha)箱(xiang)等(deng)開始投資高，但可從節約造(zao)(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)工(gong)(gong)(gong)時、提高產(chan)(chan)(chan)品質量(liang)方面(mian)得(de)到(dao)補償。低壓鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)、壓鑄(zhu)(zhu)(zhu)、離心鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)等(deng)鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)(zao)方法(fa)(fa)，因設備和模具的(de)(de)價格昂(ang)貴，所以只(zhi)適合批(pi)量(liang)生(sheng)產(chan)(chan)(chan)。
3，鑄(zhu)鐵(tie)平(ping)板(ban)造(zao)型(xing)方法(fa)應適(shi)合(he)工(gong)廠條件(jian)，例如(ru)同樣(yang)是生(sheng)產大型(xing)機床(chuang)床(chuang)身等(deng)鑄(zhu)件(jian)，一般采用組芯造(zao)型(xing)法(fa)，不制作模(mo)樣(yang)和砂(sha)箱(xiang)(xiang)，在(zai)地坑中組芯；而另外的(de)工(gong)廠則(ze)采用砂(sha)箱(xiang)(xiang)造(zao)型(xing)法(fa)，制作模(mo)樣(yang)。不同的(de)企業生(sheng)產條件(jian)(包(bao)括設備、場地、員(yuan)工(gong)素質等(deng))、生(sheng)產習(xi)慣、所積累的(de)經驗各不一樣(yang)，應該根據這些(xie)條件(jian)考慮(lv)適(shi)合(he)做(zuo)什么(me)產品和不適(shi)合(he)(或不能)做(zuo)什么(me)產品。
4，優先采用(yong)砂(sha)(sha)型(xing)(xing)鑄(zhu)(zhu)造據統(tong)計在(zai)全部鑄(zhu)(zhu)鐵平板鑄(zhu)(zhu)件產(chan)(chan)量中(zhong)，60～70的(de)(de)鑄(zhu)(zhu)件是(shi)用(yong)砂(sha)(sha)型(xing)(xing)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)的(de)(de)，而(er)且其中(zhong)70左右是(shi)用(yong)粘土砂(sha)(sha)型(xing)(xing)生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)的(de)(de)。主要原因是(shi)砂(sha)(sha)型(xing)(xing)鑄(zhu)(zhu)造較(jiao)之其它鑄(zhu)(zhu)造方法成本低、生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)工藝簡單、生(sheng)(sheng)(sheng)(sheng)產(chan)(chan)周期短。
一般來講(jiang)，對于中、大型(xing)鑄(zhu)(zhu)(zhu)件(jian)，鑄(zhu)(zhu)(zhu)鐵(tie)件(jian)可以用(yong)樹脂自(zi)硬砂(sha)(sha)型(xing)、鑄(zhu)(zhu)(zhu)鋼件(jian)可以用(yong)水玻璃砂(sha)(sha)型(xing)來生產，可以獲得(de)尺寸、表面光潔的(de)(de)鑄(zhu)(zhu)(zhu)件(jian)，但成本較高。當然，砂(sha)(sha)型(xing)鑄(zhu)(zhu)(zhu)造(zao)生產的(de)(de)鑄(zhu)(zhu)(zhu)件(jian)度(du)、表面光潔度(du)、材(cai)質(zhi)的(de)(de)密度(du)和金(jin)相組織、機(ji)械性能(neng)(neng)等方面往往較差，所以當鑄(zhu)(zhu)(zhu)件(jian)的(de)(de)這些性能(neng)(neng)要求 高時(shi)，應該采用(yong)其它鑄(zhu)(zhu)(zhu)造(zao)方法，例如熔模(mo)(失臘)鑄(zhu)(zhu)(zhu)造(zao)、壓鑄(zhu)(zhu)(zhu)、低壓鑄(zhu)(zhu)(zhu)造(zao)等等。
泊鑄(zhu)(zhu)機械量具廠鑄(zhu)(zhu)鐵平(ping)板(ban)完全按照(zhao) 標準確GB7947-1999《鑄(zhu)(zhu)鐵平(ping)板(ban)》級別分(fen)為0、1、2、3， 刨5個級別。其中2級以上為檢驗平(ping)板(ban)，3級為劃線平(ping)板(ban)或基礎(chu)平(ping)板(ban)。
鑄鐵平(ping)板(ban)結構(gou)：筋板(ban)式(shi)(shi)和(he)(he)單圍箱(xiang)型(xing)，雙圍箱(xiang)型(xing)。為保證度穩定和(he)(he)滿足(zu)載(zai)重(zhong)等(deng)要(yao)求，臺(tai)面(mian)下方為立式(shi)(shi)筋板(ban)結構(gou)。對于需(xu)要(yao)承載(zai)較大重(zhong)量的鑄鐵平(ping)板(ban)，應采(cai)用立式(shi)(shi)工字 筋板(ban)。我(wo)公司鑄鐵平(ping)板(ban)擁有多(duo)樣式(shi)(shi)，多(duo)型(xing)號規格，多(duo)用途，工藝，做(zuo)工細(xi)，價格實，訂購熱線：0317-8380005 13643379658！
