1.Ukukhethwa kwezinto ezibonakalayo: Khetha izinto ezifanelekileyo zokuvelisa i-nut, izinto eziqhelekileyo ziquka i-carbon steel, insimbi engenasici, i-aluminium alloy, njl.
I-2.Ukulungiswa kwezinto: Ukucubungula kunye nokucubungula izinto ezikhethiweyo ezikhethiweyo, kubandakanywa ukucheba, ukugoba okubandayo, okanye iinkqubo zokutshisa ezishushu, ukufezekisa imilo efunekayo kunye namandla ezinto eziphathekayo.
3.Ukucutshungulwa kwemisonto: Ngokwenza iinkqubo ezifana nokujika, ukugaya, kunye nokugaya, i-cylinder yangaphandle ye-nut icutshungulwa ibe ngumngxuma ongaphakathi kunye nentambo ethile.Eli nyathelo lidla ngokufuna ukusetyenziswa koomatshini abakhethekileyo bokulungisa imisonto.
Unyango lwe-4.Heat: Ubushushu buphatha i-nut ukuphucula ubunzima kunye namandla.Iindlela zokunyanga ukushisa zinokucinywa, ukuvutha, njl.
5.Unyango lwangaphandle: Phatha umphezulu wangaphandle weivili nutukuphucula ukuguda kwayo kunye nokusebenza okuchasene nokubola.Iindlela eziqhelekileyo zonyango lomphezulu ziquka i-galvanizing, i-nickel plating, ukutshiza, njl.
6.Ukuhlolwa komgangatho: Ukuqhuba uhlolo lomgangatho kumandongomane ukuqinisekisa ukuba imilinganiselo yawo, imisonto, kunye neempawu zoomatshini ziyahlangabezana neemfuno.Iindlela zokuhlola eziqhelekileyo ziquka ukuhlolwa kwembonakalo, ukulinganisa ubungakanani, ukuhlolwa kwentambo, njl.
7.Ukupakishwa kunye nokuhanjiswa: Amantongomane aphumelele ukuhlolwa aya kufakwa kwaye alungiselelwe ukuhanjiswa.
