Indlela yokubumba:

① Vula ukubumba (ukubunjwa simahla)

Kubandakanya iindidi ezintathu: ukungunda kwesanti emanzi, ukungunda kwesanti eyomileyo, kunye nokungunda kwesanti eqiniswe ngamachiza;

② Imodi evaliweyo yokubumba

Ukuphosa okukhethekileyo kusetyenziswa isanti yendalo yezimbiwa kunye negrabile njengeyona nto iphambili yokubumba (efana nokuphosa utyalo-mali, udaka lodaka, ukuphosa iqokobhe leworkshop, ukuphosa uxinzelelo olubi, ukuphosa okuqinileyo, ukuphosa nge-ceramic, njl.);

③ Ezinye iindlela zokuhlela zokubumba

Ngokutsho kweqondo lokushisa lokuguqula, ukubunjwa kunokwahlulahlulwa kwi-forging eshushu (iqondo lokushisa eliphezulu ngaphezu kobushushu be-recrystallization ye-billet metal), i-forging efudumeleyo (ngaphantsi kweqondo lokushisa eliphantsi kwe-recrystallization), kunye ne-cold forging (kwiqondo lokushisa lokushisa).
