Forgingsukwakhiwa kosayizi wenqubo kanye nokukhetha kwenqubo kwenziwa ngesikhathi esifanayo, ngakho-ke, amaphuzu alandelayo kufanele anakwe lapho uklama usayizi wenqubo:
(1) Landela umthetho wevolumu engashintshi, ubukhulu benqubo yokuklama kufanele buhambisane namaphuzu abalulekile enqubo ngayinye; Ngemva kwenqubo, ivolumu ngaphambi kwenqubo ilingana nevolumu ephelele ngemva kwenqubo. Isamba esiphelele sisho isamba sevolumu yemikhiqizo eqediwe kancane etholwe inqubo kanye nevolumu yokulahleka kwempahla okwenzeka kule nqubo.
(2) Kumele kulinganiswe ohlelweni lokuguqulwa kwe-billet izinguquko ezithile, okushiya ukuncipha nomshuwalense okwanele, ukugwema ubukhulu bokubekezelelana, njengokubhoboza kuzonciphisa ukuphakama okubi, ukuphakama kwe-billet kuzokhula lapho kabusha.
(3) Usayizi wemikhiqizo eseqediwe kancane etholwe kunqubo eyodwa kufanele uvumele inqubo elandelayo ukuthi iqhubeke kahle. Isibonelo, lapho uqala ukudonsa isikhathi eside bese uyacasula, awukwazi ukudonsa isikhathi eside, ngaphandle kwalokho ukucasula kuzokwenziwa ukuba kungabi namandla futhi agobe.
(4) Lapho wakha izingxenye, kubalulekile ukuqinisekisa ukuthi ingxenye ngayinye inomthamo owanele.

(5) Ninimulti-fire forging, kungenzeka ukuthi ukushisa okuphakathi komlilo ophakathi kufanele kucatshangelwe, njengobukhulu beinqubo yokuqamba, umlilo ophakathi, umkhiqizo ophelile ungafakwa ekushiseni kwesithando somlilo nokunye.
(6) Kumele ishiye ukulungiswa okwanele kokugcina, ukuze kwenziwe ingaphezulu lezinto eziqanjiwe zishelele futhi ubude nobukhulu obufanele.
(7) Isikhathi esideama-shaft forgingsubude obudingekayo ubukhulu besiqondiso bunembile kakhulu, kufanele kulinganiselwa ukuthi usayizi wobude uzonwetshwa kancane lapho ugqoka.
Inani lekhanda lokusika leama-shaft forgingskufanele ihlangabezane nezidingo.
