Ukucofa (okwaziwa ngokuba nokucinezela) yinkqubo yokubeka isinyithi esithambileyo okanye i-coil kwifomu ye-coil kwi-stamping cinezela apho isinyithi sentsimbi. Isitampu siquka iintlobo ezahlukeneyo zemveliso ye-shiti, ezinjengokucofa usebenzisa umatshini wokushicilela okanye ukucinezela, ukutshiza, ukugoba, nokucwangcisa. [1] Oku kunokuba ngumsebenzi wenqanaba elinye apho ukubetha kwamaphephandaba ivelisa ifom oyifunayo kwinxalenye yesinyithi, okanye yenzeka ngothotho lwamanqanaba. Inkqubo idla ngokuqhutywa kwi-Iron yephepha, kodwa inokusetyenziswa kwezinye izinto, ezinjenge-polystyrene. I-dies enkuthazayo idla ngokutyiswa kwikhohlakalo yentsimbi, i-coel yokungavunyelwa ngokungathandabuzekiyo ukuya kwinqanaba le-coin ukuya kwinqanaba kwaye life ngokobude bokutya kunye nokufa. Kuxhomekeke kubunzima benxalenye, inani lezikhululo ezikufa lingagqitywa.
