Kwiinkqubo zanamhlanje zoshishino, umbhobho wentsimbi ongenamthungo yinto ebalulekileyo ebalulekileyo. Ulwakhiwo lwawo olungenamthungo luwenza ube ngumthwali obalulekileyo wolwelo, amandla, kunye nenkxaso yesakhiwo, nto leyo eyenza ukuba ube ngumdlali weqonga “imithambo yegazi yentsimbi” yehlabathi lezoshishino.
Inzuzo ephambili yombhobho wentsimbi engenamthungo ikwisakhiwo sayo sesinyithi esidibeneyo. Ngokungafaniyo nemibhobho edibeneyo, efuna ukudityaniswa ukuze kwenziwe, imibhobho yentsimbi engenamthungo icutshungulwa ngokuthe ngqo ukusuka kwi-billets zentsimbi eqinileyo ukuya kwiityhubhu ezingenanto ngokusebenzisa iinkqubo ezifana nokuqengqeleka okushushu, ukutsalwa okubandayo, okanye ukukhupha. Le nkqubo isusa ubuthathaka obunokubakho kwimithungo edibeneyo, okubangela ukumelana okuphezulu koxinzelelo, ukutywinwa, kunye nokuzinza kwesakhiwo xa iphantsi koxinzelelo oluphezulu, ubushushu obuphezulu, ubushushu obuphantsi, okanye imidiya ebolileyo. Nokuba yimibhobho yeoyile negesi ekude, imibhobho yomphunga enobushushu obuphezulu yeebhoyila zezityalo zamandla, okanye izinto ezichanekileyo zesakhiwo kwishishini leenqwelo moya, umbhobho wentsimbi engenamthungo lukhetho olukhethwayo ngenxa yokusebenza kwayo okuthembekileyo.
Ngokwembono yemveliso, inkqubo yokuvelisa umbhobho wentsimbi engenamthungo iyinkimbinkimbi kwaye iyinkimbinkimbi, ikakhulu yahlulwe ngokwe-hot-roll kunye ne-cold drawing (cold rolling). Imibhobho yentsimbi engenamthungo eshushu yenziwa ngeenkqubo ezifana nokufudumeza i-billet, ukubhoboza, ukuqengqeleka, kunye nobukhulu. Imveliso egqityiweyo inobubanzi obukhulu kunye nobukhulu bodonga obufanayo, okwenza ukuba ifaneleke kwizakhiwo ezinkulu zobunjineli. Imibhobho yentsimbi engenamthungo ebandayo, eqhutyelwe phambili ngokuzoba okubandayo emva kokuqengqeleka okushushu, ifikelela ekuchanekeni okuphezulu kunye nokugqitywa okungcono komphezulu. Zisetyenziswa rhoqo kwizicelo ezifuna ukuchaneka okungqongqo, njengeemoto, oomatshini, kunye nezixhobo zonyango.
Iipayipi zentsimbi ezingenamthungo zisetyenziswa kumacandelo amaninzi abalulekileyo kuqoqosho lwelizwe. Kwishishini lamandla, zizinto eziphambili zokukhupha ioyile negesi kunye neenethiwekhi zemibhobho, ezikwaziyo ukumelana noxinzelelo oluphezulu oluphantsi komhlaba kunye neendawo ezintsonkothileyo zejoloji. Kwimveliso yoomatshini, zicutshungulwa zibe zizinto ezibalulekileyo ezifana neespindle zezixhobo zoomatshini kunye neesilinda zehydraulic, ukuqinisekisa ukuhanjiswa kwamandla kunye nokusebenza ngokuchanekileyo. Kumacandelo okwakha kunye neziseko zophuhliso, iipayipi zentsimbi ezingenamthungo ezinkulu zisetyenziswa kwiziseko zesinyithi zezakhiwo eziphakamileyo kakhulu kunye neepali zebhulorho, ukuqinisekisa ukhuseleko lweprojekthi. Kwanakwimizi-mveliso ephezulu efana neenqwelo-moya kunye namandla enyukliya, iipayipi zentsimbi ezingenamthungo ezenziwe ngee-alloys ezikhethekileyo zigcina ukusebenza okuzinzileyo phantsi kweemeko zokusebenza ezinzima.
Ngokuqhubeka nokuqhubela phambili kwetekhnoloji yemizi-mveliso, imibhobho yentsimbi engenamthungo nayo iphuhlisa ukusebenza okuphezulu kunye nokuphuculwa okukhulu. Ngophuhliso lwezinto ezintsha ze-alloy, ukugqwala kunye nokumelana nobushushu obuphezulu kwemibhobho yentsimbi engenamthungo kuyaqhubeka nokuphucuka. Ukusebenzisa izixhobo zemveliso ezikrelekrele, ukunyamezelana okulinganayo kuya kucaca ngakumbi, kuhlangabezana neemfuno ezenziwe ngokwezifiso zamashishini ahlukeneyo. Njenge "imithambo yegazi yentsimbi" yenkqubo yemizi-mveliso, enamandla kunye nokuqina, imibhobho yentsimbi engenamthungo ibisoloko isisiseko esibalulekileyo sokuqhuba ukuphuculwa kwemveliso kunye nokuqinisekisa ukwakhiwa kweeprojekthi ezinkulu.
