Gutera umucangani uburyo bukoreshwa cyane muburyo bwo gutara, bushobora kugabanywa mubice byo gutema ibumba, guta umucanga utukura, no guta umucanga. Umucanga ukoreshwa mubusanzwe ugizwe numusenyi wo hanze hamwe nintangiriro (mold). Bitewe nigiciro gito kandi byoroshye kuboneka kubikoresho byakoreshejwe muriumusenyi, kimwe nubushobozi bwabo bwo kongera gukoreshwa inshuro nyinshi, gutunganya byoroshye, no gukora byihuse mubikorwa byo guta umucanga, kuva kera byabaye inzira gakondo gakondo mugukora ibyuma, ibyuma, na aluminiyumu, bigatuma bikenerwa mubyiciro byinshi kandi binini.
Nk’uko iperereza ryabigaragaje, kuri ubu mu nganda mpuzamahanga z’abakinnyi ba casting, 65-75% by’abakinnyi baterwa kandi bikozwe mu musenyi, kandi umusaruro w’ibumba bingana na 70%. Impamvu nyamukuru nuko guta umucanga bifite igiciro gito, uburyo bworoshye bwo kubyaza umusaruro, igihe gito cyo gukora ugereranije nubundi buryo bwo guta, kandi hari nabakozi benshi ba tekinike bakora umwuga wo guta umucanga. Ibice byinshi byimodoka, ibice byubukanishi, ibyuma byuma, ibice bya gari ya moshi, nibindi byakozwe hifashishijwe ikoranabuhanga ryibumba ryumucanga. Mugihe ifu itose idashobora kuzuza ibisabwa, tekereza gukoresha umucanga wibumba wumucanga wumucanga cyangwa ubundi bwoko bwumucanga. Uburemere bwa casting yakozwe numucanga wicyatsi kibisi gishobora kuva ku kilo gito kugeza ku kilo icumi, ugatera uduce duto duto kandi duto duto, mugihe imyanda yakozwe numucanga wumye wibumba irashobora gupima toni icumi. Uburyo butandukanye bwo guta umucanga bufite inyungu zidasanzwe, bityo guta umucanga ninzira yo kubumba igice kinini cyibikorwa byo guta. Mu myaka yashize, bamwe mu bakora inganda zitera umucanga mu Bushinwa bahujije gutunganya umucanga mu buryo bwikora, ibikoresho byo kubumba umucanga, naibikoresho byikora byikorakugirango ugere ku musaruro unoze, uhendutse, kandi nini nini isanzwe ikora kandi ikanakina casting zitandukanye. Imashini ya Juneng nayo ihora yegera ubuziranenge mpuzamahanga.
