Sika kwaye ugobe ityhubhu yobhedu ibe yimo nge-Hairpin Bender kunye ne-Tube Cutting Machine, emva koko usebenzise umgca we-fin press ukuze ubethe i-foil ye-aluminium ibe ngamaphiko. Landela ityhubhu elandelayo, vumela ityhubhu yobhedu idlule kumngxunya we-fin, kwaye wandise ityhubhu ukwenza ezi zimbini zilingane ngokuqinileyo ngesandisi esithe nkqo okanye isandisi esithe tyaba. Emva koko weld ujongano lwetyhubhu yobhedu, cofa ukujonga ukuvuza, hlanganisa isibiyeli, kunye nephakheji emva kokuphumelela uhlolo lomgangatho.
