1，要(yao)兼顧(gu)鑄(zhu)(zhu)鐵平板鑄(zhu)(zhu)件(jian)(jian)的(de)(de)度(du)(du)要(yao)求和(he)成本(ben)各種鑄(zhu)(zhu)造方(fang)法(fa)(fa)所獲(huo)得的(de)(de)鑄(zhu)(zhu)件(jian)(jian)度(du)(du)不同，初投資和(he)生(sheng)產率也不一致，終的(de)(de)經濟效益(yi)也有(you)差異。因此，要(yao)做到多、快、好、省， 應當兼顧(gu)到各個方(fang)面。應對所選(xuan)用的(de)(de)鑄(zhu)(zhu)造方(fang)法(fa)(fa)進行初步(bu)的(de)(de)成本(ben)估算(suan)，以(yi)確定經濟效益(yi)高(gao)又(you)能保證鑄(zhu)(zhu)件(jian)(jian)要(yao)求的(de)(de)鑄(zhu)(zhu)造方(fang)法(fa)(fa)。
2，鑄(zhu)(zhu)鐵平(ping)板鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)方(fang)(fang)法(fa)(fa)應(ying)(ying)(ying)和(he)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)批(pi)(pi)量相適應(ying)(ying)(ying)，例如砂型(xing)(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)，大量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)工(gong)廠(chang)應(ying)(ying)(ying)創造(zao)(zao)(zao)(zao)(zao)條件(jian)(jian)(jian)采(cai)(cai)用(yong)技術的(de)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)、造(zao)(zao)(zao)(zao)(zao)芯(xin)(xin)方(fang)(fang)法(fa)(fa)。老式(shi)的(de)震(zhen)擊(ji)式(shi)或震(zhen)壓(ya)式(shi)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)率不(bu)夠(gou)高(gao)(gao)，工(gong)人勞(lao)動(dong)強(qiang)度(du)大，噪聲(sheng)大，不(bu)適應(ying)(ying)(ying)大量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)要(yao)(yao)求(qiu)(qiu)，應(ying)(ying)(ying)逐(zhu)步加(jia)以(yi)改(gai)造(zao)(zao)(zao)(zao)(zao)。對(dui)于(yu)小型(xing)(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)件(jian)(jian)(jian)，可(ke)以(yi)采(cai)(cai)用(yong)水(shui)平(ping)分型(xing)(xing)(xing)(xing)(xing)(xing)或垂(chui)直分型(xing)(xing)(xing)(xing)(xing)(xing)的(de)無箱(xiang)(xiang)(xiang)(xiang)高(gao)(gao)壓(ya)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)、實(shi)型(xing)(xing)(xing)(xing)(xing)(xing)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)效率又(you)高(gao)(gao)，占地面積也少；對(dui)于(yu)鑄(zhu)(zhu)件(jian)(jian)(jian)可(ke)選用(yong)各種有箱(xiang)(xiang)(xiang)(xiang)高(gao)(gao)壓(ya)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)機(ji)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)、氣沖造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)線(xian)，以(yi)適應(ying)(ying)(ying)快(kuai)速、高(gao)(gao)度(du)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)線(xian)的(de)要(yao)(yao)求(qiu)(qiu)，造(zao)(zao)(zao)(zao)(zao)芯(xin)(xin)方(fang)(fang)法(fa)(fa)可(ke)選用(yong)：冷芯(xin)(xin)盒、熱芯(xin)(xin)盒、殼芯(xin)(xin)等(deng)制(zhi)芯(xin)(xin)方(fang)(fang)法(fa)(fa)。中等(deng)批(pi)(pi)量的(de)大型(xing)(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)件(jian)(jian)(jian)可(ke)以(yi)考慮應(ying)(ying)(ying)用(yong)樹脂自硬砂造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)和(he)造(zao)(zao)(zao)(zao)(zao)芯(xin)(xin)。單件(jian)(jian)(jian)小批(pi)(pi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)重型(xing)(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)件(jian)(jian)(jian)，手工(gong)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)仍是(shi)重要(yao)(yao)的(de)方(fang)(fang)法(fa)(fa)，手工(gong)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)能適應(ying)(ying)(ying)各種復雜的(de)要(yao)(yao)求(qiu)(qiu)比(bi)較靈活，不(bu)要(yao)(yao)求(qiu)(qiu)很(hen)多(duo)(duo)工(gong)藝(yi)裝備。批(pi)(pi)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)或長(chang)期生(sheng)(sheng)(sheng)產(chan)(chan)(chan)的(de)定型(xing)(xing)(xing)(xing)(xing)(xing)產(chan)(chan)(chan)品(pin)采(cai)(cai)用(yong)多(duo)(duo)箱(xiang)(xiang)(xiang)(xiang)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)、劈(pi)箱(xiang)(xiang)(xiang)(xiang)造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)法(fa)(fa)比(bi)較適宜，雖然模具(ju)、砂箱(xiang)(xiang)(xiang)(xiang)等(deng)開(kai)始投資(zi)高(gao)(gao)，但可(ke)從(cong)節約造(zao)(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)(xing)工(gong)時、提高(gao)(gao)產(chan)(chan)(chan)品(pin)質量方(fang)(fang)面得到補償(chang)。低壓(ya)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)、壓(ya)鑄(zhu)(zhu)、離心鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)等(deng)鑄(zhu)(zhu)造(zao)(zao)(zao)(zao)(zao)方(fang)(fang)法(fa)(fa)，因設備和(he)模具(ju)的(de)價格昂貴，所(suo)以(yi)只(zhi)適合(he)批(pi)(pi)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)。
3，鑄(zhu)鐵平板造型方法應適合(he)工(gong)廠(chang)條件，例如(ru)同樣是(shi)生(sheng)產大型機床床身等鑄(zhu)件，一般采用(yong)組芯造型法，不(bu)制作(zuo)模(mo)樣和(he)砂箱(xiang)(xiang)，在地(di)坑(keng)中組芯；而另外的(de)工(gong)廠(chang)則采用(yong)砂箱(xiang)(xiang)造型法，制作(zuo)模(mo)樣。不(bu)同的(de)企業生(sheng)產條件(包括設備、場地(di)、員工(gong)素質等)、生(sheng)產習慣、所積累的(de)經驗各不(bu)一樣，應該(gai)根(gen)據這些條件考慮適合(he)做(zuo)什么產品(pin)和(he)不(bu)適合(he)(或(huo)不(bu)能)做(zuo)什么產品(pin)。
4，優(you)先采用砂(sha)(sha)型(xing)(xing)鑄(zhu)造(zao)據統(tong)計在(zai)全(quan)部(bu)鑄(zhu)鐵(tie)平板(ban)鑄(zhu)件產(chan)量(liang)中(zhong)，60～70的鑄(zhu)件是(shi)用砂(sha)(sha)型(xing)(xing)生(sheng)產(chan)的，而且(qie)其中(zhong)70左右(you)是(shi)用粘土砂(sha)(sha)型(xing)(xing)生(sheng)產(chan)的。主要原因是(shi)砂(sha)(sha)型(xing)(xing)鑄(zhu)造(zao)較之其它(ta)鑄(zhu)造(zao)方法成本低、生(sheng)產(chan)工藝簡單、生(sheng)產(chan)周期短。
一般來(lai)講(jiang)，對于中、大型(xing)鑄件(jian)(jian)，鑄鐵件(jian)(jian)可以用(yong)樹脂(zhi)自硬(ying)砂(sha)型(xing)、鑄鋼件(jian)(jian)可以用(yong)水玻璃砂(sha)型(xing)來(lai)生產(chan)，可以獲得(de)尺(chi)寸、表面光(guang)潔的鑄件(jian)(jian)，但成本較高。當然，砂(sha)型(xing)鑄造生產(chan)的鑄件(jian)(jian)度(du)(du)、表面光(guang)潔度(du)(du)、材(cai)質的密度(du)(du)和(he)金相組織、機(ji)械(xie)性能(neng)等方面往往較差，所(suo)以當鑄件(jian)(jian)的這(zhe)些性能(neng)要求 高時，應該采用(yong)其它鑄造方法，例(li)如(ru)熔模(mo)(失臘)鑄造、壓鑄、低(di)壓鑄造等等。
泊(bo)鑄機(ji)械(xie)量具廠鑄鐵平板(ban)(ban)完全按照(zhao) 標準確GB7947-1999《鑄鐵平板(ban)(ban)》級別分為0、1、2、3， 刨5個級別。其(qi)中2級以上為檢驗平板(ban)(ban)，3級為劃線平板(ban)(ban)或基(ji)礎平板(ban)(ban)。
鑄鐵(tie)(tie)平板(ban)結(jie)構(gou)：筋(jin)板(ban)式和單圍箱型(xing)，雙圍箱型(xing)。為保證度穩定和滿足載重等要求，臺面(mian)下方為立式筋(jin)板(ban)結(jie)構(gou)。對(dui)于需要承載較(jiao)大重量的(de)鑄鐵(tie)(tie)平板(ban)，應采用立式工字 筋(jin)板(ban)。我公司鑄鐵(tie)(tie)平板(ban)擁(yong)有多樣式，多型(xing)號規格，多用途，工藝，做工細，價格實，訂購熱(re)線：0317-8380005 13643379658！
