Ama-forging amakhulu, ngenxa yobukhulu bawo obukhulu, izinqubo eziningi, umjikelezo omude, ukungafani kwenqubo, nezici eziningi ezingazinzile, ngokuvamile zibangela ukungafani okungathí sina ku-microstructure, ukuze bangakwazi ukuphumelela ukuhlolwa kwempahla yemishini, ukuhlolwa kwe-metallographic kanye nokungewona- ukutholwa kwamaphutha okulimazayo.

Ngenxa yokuhlukaniswa kokwakheka kwamakhemikhali, ukuqoqwa kokufakwa kanye nokukhubazeka okuhlukahlukene kwe-pore ku-ingot;
Lapho kushisa, izinga lokushisa lishintsha kancane, ukusatshalaliswa kungalingani, ukucindezeleka kwangaphakathi kukhulu, iphutha liningi;
Ukushisa okuphezulu kanye nokukhanga isikhathi eside, ukucindezeleka kwendawo kanye nokuguqulwa kwendawo, isimo sokugeleza kwepulasitiki, izinga lokuhlanganisa, ukusatshalaliswa kwe-deformation kuhluke kakhulu;
Ngesikhathi sokupholisa, inqubo yokusabalalisa ihamba kancane, ukuguqulwa kwezicubu kuyinkimbinkimbi futhi ukucindezeleka okwengeziwe kukhulu.
Zonke lezi zici ezingenhla zingase ziholele ekuhlukeni okukhulu kokusebenza kwezicubu kanye nekhwalithi engafanelekile.
Izinyathelo zokuthuthukisa ukufana kweama-forging amakhulu:
1. Yamukela ubuchwepheshe obuthuthukisiwe bokuncibilika ukuze uthuthukise ikhwalithi yensimbi yensimbi;
2. I-Adopt control forging, lawula ubuchwepheshe bokupholisa, uthuthukise inqubo yezobuchwepheshe, futhi uthuthukise izinga lobuchwepheshe nezomnotho lokukhiqiza okukhulu kwe-forging.
