Iyo yekudya inokandwa iyo yakagadzirwa mune iyi maitiro inogona kusiyana zvakanyanya muhukuru uye uremu, kubva kumabhangi emapaunzi kusvika zana emapaundi. Imwe yakajairika yekunyorera yefa yakakwenenzverwa zvikamu zvakakwenenzverwa, zvakaonda-akavharidzirwa, kazhinji achida mbabvu zhinji nehombodo pane zvemukati. Muruzimba dzesimbi dzemhando dzakasiyana dzemidziyo nemidziyo kazhinji dzinowanzofa. Zvikamu zvinoverengeka zvemotokari zvinogadzirwawo uchishandisa die casting, kusanganisira pistons, misoro yecylinder, uye mashiripiti eshimu. Zvimwe zvakajairika zvakakandwa zvikamu zvinosanganisira zvimedu, magiya, bushings, mapapu, uye mavheni.
Die casting iri yekugadzira inogadzira iyo inogona kuburitsa geometrically yakaoma zvidimbu zvesimbi kuburikidza nekushandiswa kwekushandiswazve, kunonzi kunofa. Iyo yekufa yekukanda maitiro inosanganisira kushandiswa kwechoto, simbi, dife casting muchina, uye kufa. Iyo simbi, kazhinji isingaiti-isina-ferus alody yakadai sealuminium kana zinc, yakanyungudutswa muvira uye ikazadzwa mufa mune dife casting muchina. Kune marudzi maviri makuru ekufa anokanda michina - inopisa kamuri (inoshandiswa kune madhiri ane tembiricha yakadzika yekunyungudika, yakadai yeColy champies Misiyano iri pakati pemachina aya ichatsanangurwa muzvikamu pamidziyo uye yekushandisa. Nekudaro, mumachina ese ari maviri, mushure mekunge simbi yakanyungudutswa yakaiswa mufa, inokudza uye inokudza uye inosimbisa muchikamu chekupedzisira, inonzi casting. Matanho ari mune ino maitiro anotsanangurwa zvakadzama muchikamu chinotevera.
Difa zvakakandwa zvikamu zvinogona kusiyana zvakanyanya muhukuru uye saka zvinoda matanho aya kufukidza yakakura kwazvo huwandu. Nekuda kweizvozvo, di di casting michina yakagadzirirwa kune imwe neimwe inogara diki yehuwandu hweiyi yakakura spectrum yetsika. Sampula yakatarwa kamuri dzinoverengeka dzakasiyana dzinopisa uye dzinotonhora dzimba dzinofa dzinokanda michina dzinopihwa pazasi.

Kusarudzwa kwechinyorwa kune kufa kukandirwa kunoenderana nezvinhu zvinoverengeka zvinosanganisira density, inonyungudika, simba, kushora kuramba, uye mutengo. Izvo zvinyorwa zvinogona kukanganisawo chikamu chekugadzira. Semuenzaniso, kushandiswa kweZinc, iyo iri simbi yakanyanya ductle, inogona kubvumira madziro akaonda uye kupedzisa kuri nani pane mamwe akawanda alloys. Izvo zvinyorwa hazvisi kungo tarisa zvivakwa zvekukanda kwekupedzisira, asi zvakare zvinokanganisa muchina uye kushandisira. Zvishandiso zvine mongororo yakadzika yekunyungudika, senge a zinc alloys, inogona kunge iri kufa yakakandwa mukamuri inopisa chambera. Nekudaro, zvigadzirwa zvine yakakwira yekunyungudika tembiricha, yakadai sealuminium uye yemhangura alloys, inoda kushandiswa kwechirango chichitonhora. Iyo yekunyungudika tembiricha inokanganisawo kushandisika, sezvo tembiricha yakanyanya ichave nemhedzisiro yakakura pane hupenyu hwekufa.
