A. Pfupiso yekuyerera kwemaitiro
Kupisa kukungurutswa (extrusion seamless simbi chubhu) : round chubhu billet → kudziyisa → perforation → matatu-yakakwirira muchinjiko kukunguruka, kuenderera kutenderera kana extrusion → chubhu kuburitsa → saizi (kana kuderedza) → kutonhora → billet → kutwasanuka → hydrostatic bvunzo (kana kuona kukanganisa) → kumaka → kuchengetedza.
Inotonhora-inodhonzwa (yakakungurutswa) isina musono chubhu yesimbi: yakatenderedza chubhu billet → kudziyisa → perforation → musoro → annealing → pickling → mafuta ekuzora (mhangura yemhangura) → yakawanda-inopfuura inotonhora kudhirowa (inotonhora kukunguruka) → billet → kupisa kupisa → kutwasanura → hydrostatic bvunzo (kuona kukanganisa) → kumaka → kuchengetedza.
