1. Yintoni iMetal Casting? Inkcazo kunye neMithetho engundoqo
1.1 Ukuchaza inkqubo: ukusuka kwipatheni ukuya inxalenye yentsimbi
Ukwenziwa kwesinyithi yinkqubo yokwenziwa apho isinyithi esinyibilikisiweyo sigalelwa kumgodi wokungunda ophindaphinda indawo efunekayo yejometri, ukuyivumela ukuba yomelele ibe yinto egqityiweyo okanye ekufutshane-esele igqityiwe. Umjikelo osisiseko wokuphosa unamanyathelo amaninzi abalulekileyo: ukwenza iipateni, ukubumba, ukunyibilika, ukugalela, ukuqinisa, ukupholisa, kunye nokugqiba. Ipateni, eyenziwa ngamaplanga, isinyithi, okanye iplastiki, idala umngxuma ekubumbeni. Kwiijometri zangaphakathi ezintsonkothileyo, ii-cores zifakelwe ukwenza iipaseji ezifana nezo zikwimpompo kunye ne-valve castings. Emva kokuba isikhunta silungisiwe, i-alloy ekhethiweyo-njengentsimbi engwevu okanye i-ductile iron-incibilika kwisithando somlilo (i-cupola, i-electric induction, okanye i-arc furnace yombane) kwaye igalelwe kumaqondo okushisa alawulwa ngokucophelela. Ukuqina kuqala njengoko intsimbi iphola, iguquka ukusuka kulwelo ukuya kwisiqina ngaphakathi kokungunda. Emva kokuqiniswa ngokupheleleyo, ukuphosa kuyashukunyiswa, kucocwe, kunyangwa ngobushushu xa kukho imfuneko, kwaye kwenziwe ngoomatshini ukuze kunyanyezelwe okokugqibela.
Kutheni iinxalenye zentsimbi zilawula oomatshini: Intsimbi yentsimbi ihlala iyeyona nto ikhethwayo kwizicelo ezingenakubalwa zemizi-mveliso ngenxa yezinto ezintathu eziluncedo zendalo: ukunyibilika kwe-vibration, ukuxhathisa ukunxiba, kunye nokusebenza kakuhle.
