| Into | Ukubumba | Ukuphosa |
| Inkqubo | Ukubumba yinkqubo apho ukusebenzisa umatshini wokubumba ukwenza intsimbi ingenanto kuvelisa ukuguqulwa kweplastiki, ukuze kufunyanwe iimpawu ezithile zoomatshini, imilo kunye nobukhulu. Ngokubumba kunokususa iziphene ezikhululekileyo zesinyithi kwinkqubo yokunyibilikisa, kwenze ngcono ulwakhiwo lwe-microstructure, kugcine ukuhamba kwesinyithi okupheleleyo, ngoko ke iimpawu zoomatshini zokubumba zingcono kakhulu kunokubumba izinto ezifanayo. Uninzi lwamacandelo abalulekileyo omatshini afuna umthwalo omkhulu kwaye imeko yokusebenza enzima isebenzisa iindawo zokubumba. | Ukuphosa yinkqubo yokufaka isinyithi esilulwelo kwindawo yokuphosa, emva kokuphola nokuqina ukuze kufunyanwe iindawo ezifunekayo. |
| Izinto eziphathekayo | Izinto zokubumba zisebenzisa kakhulu intsimbi engqukuva, intsimbi enesikwere. Kukho intsimbi yekhabhoni, intsimbi ye-alloy, intsimbi engatyiwayo kunye nezinye isinyithi ezingeyo-ferrous ezisetyenziswa kakhulu kwindawo nakwishishini lokuchaneka. | Ukuphosa kudla ngokusetyenziswa intsimbi engwevu, intsimbi ethambileyo, intsimbi ethambileyo, kunye nentsimbi ethambileyo. Ukuphosa okuqhelekileyo isinyithi esingenasinyithi: ubhedu, ubhedu lwetin, ubhedu lwewuxi, i-aluminium alloy njl. | Phantsi kwemeko efanayo, i-forgingmetal isebenza ngcono kwiipropati zoomatshini, ngelixa i-casting ingcono ekubumbeni. |
| Imbonakalo | I-oxidation reaction yentsimbi yokubumba ngexesha lenkqubo yobushushu obuphezulu iya kubangela i-kylin grain encinci kumphezulu wamazinyo ebhakethi eqingqiweyo. Kwakhona njengoko ukubumba kwenziwa ngokubumba, emva kokususa indawo yokuvumela kwisikhunta, kuya kubakho umgca wokuhlukana kwamazinyo ebhakethi eqingqiweyo. | Kukho i-sand trace kunye ne-casting kiting kumphezulu wamazinyo e-casting bucket. |
| Ipropati yoomatshini | Inkqubo yokubumba inokuqinisekisa ukuqhubeka kwefayibha yesinyithi, kwaye igcine ukuhamba kwesinyithi okupheleleyo, iqinisekise iipropati ezilungileyo zoomatshini kunye nobomi benkonzo ende yamazinyo ebhakethi, inkqubo yokubumba engenakuthelekiswa nanto. | Xa kuthelekiswa neendawo zokubumba, isakhiwo sesinyithi kunye neempawu zoomatshini zinokuphuculwa emva kokubumba. Umbutho wokubumba emva kokubumba uguquko lobushushu, ikristale enkulu yokuqala kunye nengqolowa yekholamu zitshintsha zibe ziinkozo ezintle, kunye nombutho wokuphinda uguqulwe kwe-isometric, ukuvumela isakhiwo sokwahlulwa kokuqala ngaphakathi kwe-ingot, i-osteoporosis, ukufakwa kwe-slag ye-porosity kunye nezinye izinto ezincinci ukuba zibe kufutshane ngakumbi, ngaloo ndlela kuphuculwe i-plasticity yesinyithi kunye neempawu zoomatshini.
Ukubumba kukufumana imo efunekayo ngokucinezela isinyithi ngeplastiki, ngesiqhelo ngehamile okanye ngoxinzelelo. Inkqubo yokubumba inika isakhiwo esincinci se-granular, kwaye iphucula iipropati zomzimba zesinyithi, xa isetyenziswa, uyilo olufanelekileyo lunokuqinisekisa ukuhamba kweenkozo kwicala loxinzelelo oluphambili. Ngelixa ukubumba kukufumana izinto ezenza isinyithi ngeendlela ezahlukeneyo zokubumba, oko kukuthi ukufaka isinyithi esilulwelo kwisikhunta esilungisiweyo ukuze sifumane imo ethile, ubungakanani kunye neepropati, ngokunyibilikisa, ukuphosa, ukujova okanye enye indlela yokubumba, kunye nokushukumisa emva kokupholisa, ukucoca kunye nokulungisa okokugqibela. |
