1，要兼顧(gu)鑄(zhu)鐵平板鑄(zhu)件(jian)的(de)(de)度要求(qiu)(qiu)和成(cheng)本各(ge)種鑄(zhu)造(zao)方法所獲得的(de)(de)鑄(zhu)件(jian)度不同，初投資和生產率也不一致，終的(de)(de)經(jing)濟(ji)效(xiao)(xiao)益(yi)也有差異(yi)。因此(ci)，要做到多、快、好、省， 應(ying)當兼顧(gu)到各(ge)個方面(mian)。應(ying)對所選用(yong)的(de)(de)鑄(zhu)造(zao)方法進行初步的(de)(de)成(cheng)本估算，以確定(ding)經(jing)濟(ji)效(xiao)(xiao)益(yi)高又能保證鑄(zhu)件(jian)要求(qiu)(qiu)的(de)(de)鑄(zhu)造(zao)方法。
2，鑄(zhu)(zhu)(zhu)鐵(tie)平(ping)(ping)板鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)方(fang)(fang)法(fa)(fa)(fa)應(ying)(ying)和生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)批(pi)量相適(shi)(shi)(shi)應(ying)(ying)，例(li)如砂(sha)(sha)型(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)，大(da)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)的工(gong)(gong)廠應(ying)(ying)創造(zao)(zao)(zao)(zao)條件采(cai)用(yong)(yong)技術的造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)、造(zao)(zao)(zao)(zao)芯(xin)(xin)方(fang)(fang)法(fa)(fa)(fa)。老式的震(zhen)擊(ji)式或(huo)震(zhen)壓式造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)機生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)線(xian)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)率(lv)不(bu)夠高(gao)，工(gong)(gong)人勞動強度大(da)，噪聲大(da)，不(bu)適(shi)(shi)(shi)應(ying)(ying)大(da)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)的要(yao)求，應(ying)(ying)逐步(bu)加以改造(zao)(zao)(zao)(zao)。對于小(xiao)型(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)件，可以采(cai)用(yong)(yong)水(shui)平(ping)(ping)分(fen)型(xing)(xing)(xing)(xing)(xing)或(huo)垂直分(fen)型(xing)(xing)(xing)(xing)(xing)的無箱(xiang)高(gao)壓造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)機生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)線(xian)、實(shi)型(xing)(xing)(xing)(xing)(xing)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)效率(lv)又高(gao)，占地(di)面積也少；對于鑄(zhu)(zhu)(zhu)件可選(xuan)用(yong)(yong)各種有箱(xiang)高(gao)壓造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)機生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)線(xian)、氣沖造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)線(xian)，以適(shi)(shi)(shi)應(ying)(ying)快(kuai)速、高(gao)度造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)線(xian)的要(yao)求，造(zao)(zao)(zao)(zao)芯(xin)(xin)方(fang)(fang)法(fa)(fa)(fa)可選(xuan)用(yong)(yong)：冷芯(xin)(xin)盒(he)、熱芯(xin)(xin)盒(he)、殼芯(xin)(xin)等(deng)制芯(xin)(xin)方(fang)(fang)法(fa)(fa)(fa)。中等(deng)批(pi)量的大(da)型(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)件可以考慮應(ying)(ying)用(yong)(yong)樹脂自硬砂(sha)(sha)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)和造(zao)(zao)(zao)(zao)芯(xin)(xin)。單件小(xiao)批(pi)生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)的重(zhong)型(xing)(xing)(xing)(xing)(xing)鑄(zhu)(zhu)(zhu)件，手工(gong)(gong)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)仍是重(zhong)要(yao)的方(fang)(fang)法(fa)(fa)(fa)，手工(gong)(gong)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)能適(shi)(shi)(shi)應(ying)(ying)各種復雜的要(yao)求比較靈(ling)活，不(bu)要(yao)求很多工(gong)(gong)藝裝備(bei)。批(pi)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)或(huo)長期生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)的定型(xing)(xing)(xing)(xing)(xing)產(chan)(chan)(chan)(chan)(chan)(chan)品采(cai)用(yong)(yong)多箱(xiang)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)、劈箱(xiang)造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)法(fa)(fa)(fa)比較適(shi)(shi)(shi)宜，雖然模(mo)具(ju)、砂(sha)(sha)箱(xiang)等(deng)開始(shi)投資高(gao)，但可從節約造(zao)(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)工(gong)(gong)時(shi)、提(ti)高(gao)產(chan)(chan)(chan)(chan)(chan)(chan)品質量方(fang)(fang)面得到補(bu)償。低(di)壓鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)、壓鑄(zhu)(zhu)(zhu)、離心鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)等(deng)鑄(zhu)(zhu)(zhu)造(zao)(zao)(zao)(zao)方(fang)(fang)法(fa)(fa)(fa)，因設備(bei)和模(mo)具(ju)的價格昂貴，所以只適(shi)(shi)(shi)合批(pi)量生(sheng)(sheng)(sheng)產(chan)(chan)(chan)(chan)(chan)(chan)。
3，鑄鐵平板造(zao)(zao)型(xing)方(fang)法(fa)應適合(he)工廠(chang)(chang)條件，例如同樣(yang)是生產大型(xing)機床床身等鑄件，一(yi)般采(cai)(cai)用(yong)組芯造(zao)(zao)型(xing)法(fa)，不(bu)(bu)制作模(mo)樣(yang)和(he)砂箱，在地(di)坑(keng)中組芯；而另(ling)外的(de)工廠(chang)(chang)則(ze)采(cai)(cai)用(yong)砂箱造(zao)(zao)型(xing)法(fa)，制作模(mo)樣(yang)。不(bu)(bu)同的(de)企業(ye)生產條件(包(bao)括設備、場(chang)地(di)、員工素質等)、生產習(xi)慣、所積(ji)累的(de)經驗各不(bu)(bu)一(yi)樣(yang)，應該根據這(zhe)些(xie)條件考慮(lv)適合(he)做(zuo)什么(me)產品(pin)和(he)不(bu)(bu)適合(he)(或不(bu)(bu)能)做(zuo)什么(me)產品(pin)。
4，優先采用砂型鑄造據統計在全部鑄鐵(tie)平板(ban)鑄件(jian)產(chan)(chan)(chan)量中，60～70的鑄件(jian)是(shi)用砂型生(sheng)產(chan)(chan)(chan)的，而且其中70左右是(shi)用粘(zhan)土砂型生(sheng)產(chan)(chan)(chan)的。主要原(yuan)因是(shi)砂型鑄造較之其它鑄造方(fang)法(fa)成本低、生(sheng)產(chan)(chan)(chan)工藝(yi)簡單、生(sheng)產(chan)(chan)(chan)周(zhou)期短。
一(yi)般來講(jiang)，對(dui)于中、大型鑄(zhu)(zhu)件(jian)，鑄(zhu)(zhu)鐵件(jian)可(ke)以用樹脂自硬砂型、鑄(zhu)(zhu)鋼件(jian)可(ke)以用水(shui)玻璃砂型來生產，可(ke)以獲得尺寸、表(biao)面光(guang)潔(jie)的(de)(de)鑄(zhu)(zhu)件(jian)，但成本較(jiao)高(gao)。當(dang)然，砂型鑄(zhu)(zhu)造(zao)生產的(de)(de)鑄(zhu)(zhu)件(jian)度、表(biao)面光(guang)潔(jie)度、材(cai)質的(de)(de)密度和金相組織、機械性(xing)能等方面往(wang)往(wang)較(jiao)差(cha)，所以當(dang)鑄(zhu)(zhu)件(jian)的(de)(de)這些性(xing)能要(yao)求 高(gao)時，應該采用其(qi)它鑄(zhu)(zhu)造(zao)方法，例如熔模(失臘)鑄(zhu)(zhu)造(zao)、壓鑄(zhu)(zhu)、低壓鑄(zhu)(zhu)造(zao)等等。
泊鑄機械量具廠鑄鐵平板(ban)(ban)完全按照 標準(zhun)確GB7947-1999《鑄鐵平板(ban)(ban)》級別分為0、1、2、3， 刨5個級別。其中2級以上為檢驗平板(ban)(ban)，3級為劃(hua)線(xian)平板(ban)(ban)或基(ji)礎平板(ban)(ban)。
鑄鐵(tie)(tie)平板結(jie)構(gou)：筋板式和(he)(he)單(dan)圍(wei)箱(xiang)型(xing)，雙圍(wei)箱(xiang)型(xing)。為保證(zheng)度穩定(ding)和(he)(he)滿足載重(zhong)(zhong)等要求，臺面(mian)下方為立(li)式筋板結(jie)構(gou)。對(dui)于需要承(cheng)載較(jiao)大重(zhong)(zhong)量的(de)鑄鐵(tie)(tie)平板，應采用立(li)式工(gong)字 筋板。我公司(si)鑄鐵(tie)(tie)平板擁(yong)有(you)多(duo)樣式，多(duo)型(xing)號規格(ge)，多(duo)用途(tu)，工(gong)藝，做工(gong)細，價格(ge)實，訂購熱(re)線：0317-8380005 13643379658！
