Inkqubo yokwenziwa kwetyhubhu yentsimbi engenamthungo. Ngokwenkqubo yokwenziwa kwayo, ityhubhu yentsimbi engenamthungo yahlulwe yaba ityhubhu yentsimbi eshushu eqengqelekayo, ityhubhu yentsimbi ebandayo etsalwa yintsimbi, ukugqobhoza kunye nokolula ityhubhu yentsimbi engenamthungo ethe nkqo extrusion ityhubhu yentsimbi engenamthungo, iintlobo ezimbini zokuqala zenkqubo Ukuveliswa kwetyhubhu yentsimbi engenamthungo ngokubanzi, umgangatho wetyhubhu yentsimbi engenamthungo iqhelekile kwi-8-406, ubukhulu bodonga buhlala 2-25; Ezi zimbini zokugqibela kukuveliswa kombhobho wentsimbi eshinyeneyo obubanzi obukhulu, umbhobho wentsimbi ongenamthungo, ububanzi bombhobho wentsimbi ngokuqhelekileyo ukwi-406-1800, ubukhulu bodonga buhlala kwi-20mm-220mm. Ngokokusetyenziswa kwayo, inokwahlulwa ibe ityhubhu yentsimbi engenamthungo yolwakhiwo, ityhubhu yentsimbi engenamthungo yolwelo, ityhubhu yentsimbi engenamthungo yebhoyila kunye netyhubhu yentsimbi engenamthungo yombhobho weoyile.
