1，要兼(jian)(jian)顧鑄鐵平板鑄件(jian)的(de)(de)度要求和(he)成(cheng)本各(ge)種鑄造方(fang)(fang)法所獲得的(de)(de)鑄件(jian)度不(bu)同(tong)，初投資和(he)生產率也(ye)不(bu)一致，終的(de)(de)經(jing)濟(ji)效益(yi)也(ye)有差異。因(yin)此，要做到(dao)多、快、好、省(sheng)， 應(ying)當兼(jian)(jian)顧到(dao)各(ge)個方(fang)(fang)面。應(ying)對所選用的(de)(de)鑄造方(fang)(fang)法進(jin)行(xing)初步的(de)(de)成(cheng)本估算(suan)，以確(que)定經(jing)濟(ji)效益(yi)高又能保證鑄件(jian)要求的(de)(de)鑄造方(fang)(fang)法。
2，鑄(zhu)鐵平板鑄(zhu)造(zao)(zao)(zao)方法應和(he)生(sheng)(sheng)產(chan)(chan)批(pi)量(liang)(liang)(liang)相適(shi)應，例(li)如砂型(xing)(xing)(xing)(xing)(xing)鑄(zhu)造(zao)(zao)(zao)，大量(liang)(liang)(liang)生(sheng)(sheng)產(chan)(chan)的(de)(de)(de)工(gong)(gong)(gong)廠應創造(zao)(zao)(zao)條件采用(yong)(yong)技術的(de)(de)(de)造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)、造(zao)(zao)(zao)芯(xin)(xin)方法。老式的(de)(de)(de)震擊式或震壓(ya)式造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)機(ji)生(sheng)(sheng)產(chan)(chan)線生(sheng)(sheng)產(chan)(chan)率(lv)不夠高(gao)(gao)，工(gong)(gong)(gong)人(ren)勞動強度大，噪聲大，不適(shi)應大量(liang)(liang)(liang)生(sheng)(sheng)產(chan)(chan)的(de)(de)(de)要求，應逐步(bu)加以改造(zao)(zao)(zao)。對于小型(xing)(xing)(xing)(xing)(xing)鑄(zhu)件，可(ke)以采用(yong)(yong)水平分型(xing)(xing)(xing)(xing)(xing)或垂(chui)直分型(xing)(xing)(xing)(xing)(xing)的(de)(de)(de)無箱高(gao)(gao)壓(ya)造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)機(ji)生(sheng)(sheng)產(chan)(chan)線、實(shi)型(xing)(xing)(xing)(xing)(xing)造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)生(sheng)(sheng)產(chan)(chan)效率(lv)又高(gao)(gao)，占地面積也少；對于鑄(zhu)件可(ke)選(xuan)用(yong)(yong)各(ge)種(zhong)有(you)箱高(gao)(gao)壓(ya)造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)機(ji)生(sheng)(sheng)產(chan)(chan)線、氣(qi)沖造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)線，以適(shi)應快速(su)、高(gao)(gao)度造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)生(sheng)(sheng)產(chan)(chan)線的(de)(de)(de)要求，造(zao)(zao)(zao)芯(xin)(xin)方法可(ke)選(xuan)用(yong)(yong)：冷(leng)芯(xin)(xin)盒、熱(re)芯(xin)(xin)盒、殼芯(xin)(xin)等制芯(xin)(xin)方法。中(zhong)等批(pi)量(liang)(liang)(liang)的(de)(de)(de)大型(xing)(xing)(xing)(xing)(xing)鑄(zhu)件可(ke)以考慮應用(yong)(yong)樹(shu)脂自硬砂造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)和(he)造(zao)(zao)(zao)芯(xin)(xin)。單件小批(pi)生(sheng)(sheng)產(chan)(chan)的(de)(de)(de)重型(xing)(xing)(xing)(xing)(xing)鑄(zhu)件，手(shou)工(gong)(gong)(gong)造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)仍是重要的(de)(de)(de)方法，手(shou)工(gong)(gong)(gong)造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)能適(shi)應各(ge)種(zhong)復雜的(de)(de)(de)要求比較(jiao)靈活，不要求很多工(gong)(gong)(gong)藝裝備(bei)。批(pi)量(liang)(liang)(liang)生(sheng)(sheng)產(chan)(chan)或長期生(sheng)(sheng)產(chan)(chan)的(de)(de)(de)定型(xing)(xing)(xing)(xing)(xing)產(chan)(chan)品(pin)(pin)采用(yong)(yong)多箱造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)、劈箱造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)法比較(jiao)適(shi)宜，雖然模(mo)具(ju)、砂箱等開始投資高(gao)(gao)，但可(ke)從節約造(zao)(zao)(zao)型(xing)(xing)(xing)(xing)(xing)工(gong)(gong)(gong)時(shi)、提高(gao)(gao)產(chan)(chan)品(pin)(pin)質量(liang)(liang)(liang)方面得(de)到補(bu)償(chang)。低壓(ya)鑄(zhu)造(zao)(zao)(zao)、壓(ya)鑄(zhu)、離心鑄(zhu)造(zao)(zao)(zao)等鑄(zhu)造(zao)(zao)(zao)方法，因設(she)備(bei)和(he)模(mo)具(ju)的(de)(de)(de)價格昂貴，所(suo)以只適(shi)合批(pi)量(liang)(liang)(liang)生(sheng)(sheng)產(chan)(chan)。
3，鑄(zhu)鐵(tie)平(ping)板(ban)造(zao)型方法應適合(he)工(gong)(gong)廠條(tiao)件(jian)(jian)，例如同樣(yang)是生產(chan)(chan)大型機床(chuang)床(chuang)身等(deng)鑄(zhu)件(jian)(jian)，一(yi)般采用(yong)組芯(xin)造(zao)型法，不(bu)(bu)制(zhi)作(zuo)模樣(yang)和砂箱(xiang)，在地坑中組芯(xin)；而另(ling)外的(de)工(gong)(gong)廠則采用(yong)砂箱(xiang)造(zao)型法，制(zhi)作(zuo)模樣(yang)。不(bu)(bu)同的(de)企業生產(chan)(chan)條(tiao)件(jian)(jian)(包括設備、場地、員工(gong)(gong)素質(zhi)等(deng))、生產(chan)(chan)習(xi)慣、所積累的(de)經驗各不(bu)(bu)一(yi)樣(yang)，應該根據這些(xie)條(tiao)件(jian)(jian)考慮適合(he)做什么(me)產(chan)(chan)品和不(bu)(bu)適合(he)(或不(bu)(bu)能(neng))做什么(me)產(chan)(chan)品。
4，優(you)先采用砂(sha)(sha)型鑄(zhu)造(zao)據統計在全部鑄(zhu)鐵平板鑄(zhu)件(jian)產(chan)量中(zhong)，60～70的鑄(zhu)件(jian)是(shi)用砂(sha)(sha)型生產(chan)的，而且其中(zhong)70左(zuo)右是(shi)用粘土砂(sha)(sha)型生產(chan)的。主要原(yuan)因(yin)是(shi)砂(sha)(sha)型鑄(zhu)造(zao)較之(zhi)其它鑄(zhu)造(zao)方(fang)法(fa)成本低、生產(chan)工藝簡單、生產(chan)周期(qi)短。
一般來講，對于中、大型鑄(zhu)(zhu)(zhu)件，鑄(zhu)(zhu)(zhu)鐵件可以用樹脂自硬砂(sha)型、鑄(zhu)(zhu)(zhu)鋼件可以用水(shui)玻璃砂(sha)型來生產(chan)，可以獲得尺寸、表面(mian)光潔(jie)的鑄(zhu)(zhu)(zhu)件，但成本較(jiao)高。當然，砂(sha)型鑄(zhu)(zhu)(zhu)造生產(chan)的鑄(zhu)(zhu)(zhu)件度、表面(mian)光潔(jie)度、材(cai)質的密(mi)度和金(jin)相組織、機械性能等(deng)方面(mian)往往較(jiao)差(cha)，所以當鑄(zhu)(zhu)(zhu)件的這些(xie)性能要(yao)求(qiu) 高時，應(ying)該采用其它鑄(zhu)(zhu)(zhu)造方法，例如(ru)熔模(失臘)鑄(zhu)(zhu)(zhu)造、壓(ya)鑄(zhu)(zhu)(zhu)、低壓(ya)鑄(zhu)(zhu)(zhu)造等(deng)等(deng)。
泊(bo)鑄(zhu)機械量具廠鑄(zhu)鐵平(ping)板完全按(an)照 標準確(que)GB7947-1999《鑄(zhu)鐵平(ping)板》級別分為(wei)(wei)0、1、2、3， 刨(bao)5個級別。其中2級以上為(wei)(wei)檢驗平(ping)板，3級為(wei)(wei)劃線平(ping)板或基礎(chu)平(ping)板。
鑄(zhu)鐵(tie)平板結構：筋板式(shi)和(he)單圍箱型(xing)，雙圍箱型(xing)。為(wei)保證度穩定(ding)和(he)滿足載重(zhong)等要(yao)求，臺面(mian)下方為(wei)立(li)(li)式(shi)筋板結構。對于(yu)需要(yao)承載較大(da)重(zhong)量的鑄(zhu)鐵(tie)平板，應采用(yong)立(li)(li)式(shi)工(gong)字 筋板。我公司鑄(zhu)鐵(tie)平板擁(yong)有多樣式(shi)，多型(xing)號規格(ge)，多用(yong)途，工(gong)藝(yi)，做工(gong)細，價格(ge)實，訂購熱線：0317-8380005 13643379658！
