Kweli nqaku sizama ukwazisa ulwazi malunga noqikeleloiindleko zokuphoswa kwentsimbi ngobunzima. Ngokwenyani zombini iindleko zokuphosa intsimbi kunyeiicasts zentsimbizineemeko ezifanayo ezinokugqiba ukuba yimalini esiyibizayo, njengokuntsonkotha kolwakhiwo lokuphosa, ubungakanani bokuphosa, imathiriyeli kunye nobungakanani bemfuno ngenyanga okanye ngonyaka.
Ngokuqhelekileyo ukuphoswa kwentsimbi kusoloko kubiza ngaphezulu kwentsimbi. Oku kubangelwa ubukhulu becala zizinto ezimbini. Izixhobo zensimbi ezityhidiweyo zibiza kakhulu, ngakumbi i-alloys yensimbi kunye nensimbi engenasici. Ukuba abathengi bafuna iipropathi ezikhethekileyo zomatshini ezifana nokunganyangeki, ukumelana nobushushu okanye ukusebenza kwe-rust, iikhemikhali ezikhethekileyo (ezifana noMn, Mo, Cr, Ni) kufuneka zongezwe kwintsimbi etyhidiweyo ngexesha lokuphosa. Ewe kunjalo, ubushushu bonyango lobushushu, ukucima, ukuthambisa, i-carburization okanye i-normalization ihlala yenzelwe ukuphoswa kwentsimbi ukufumana iipropathi ezifunwayo zoomatshini.
Enye into ebangela ukuba ukuphosa kwentsimbi kubize kakhulu yinkqubo yokuphosa. Xa kuthelekiswa nentsimbi engwevu kunye ne-ductile cast iron, ephoswa ikakhulu ngokugalelwa kwesanti eluhlaza okanye ukubunjwa kwegobolondo, iintsimbi zentsimbi kufuneka zihlale ziveliswa yinkqubo ebizwa ngokuba yi-speical casting, kubandakanywa ukuphosa utyalo-mali (inkqubo wax elahlekileyo), ukuphoswa kwegwebu elilahlekileyo, ukuphoswa kwevacuum okanye obunye ubugcisa obutsha. Ezi nkqubo zokuphosa zingentla zinokuqinisekisa imilinganiselo echanekileyo, imiphezulu yemithombo kunye neempawu ezilungileyo zoomatshini. Ngokufanelekileyo, iindleko nazo ziya kuba phezulu kunjalo.
