Izixhobo zeetyhubhu zokubumba ubhedu kufuneka zibe zizo ezinamandla okuqina, amandla okukhathala, ubunzima obufanelekileyo, ubude obuphantsi kunye ne-coefficient yokushisa okuphezulu. Ngenxa yoko, izinto ezifana nephosphorous deoxidize ubhedu (DHP),CUAG,CR-ZR-CU zamkelwa ngokubanzi ngabasebenzisi bawo onke amazwe. Iingubo: Ubhedu lunobulukhuni obusezantsi obukhokelela kwipropathi ephantsi yokuchasana ne-abrasive. Ngoko ke, ummandla ongaphantsi kweembumba, apho uxinzelelo lwanda kakhulu ngenxa yeegobolondo, luya kugqithwa kakhulu. Ukonyusa ixesha lokuphila lokungunda kobhedu, i-uniform mold surface plating ngobulukhuni obufanelekileyo iyafuneka. Uninzi lweetyhubhu zokubumba zobhedu zobukhulu obuncinci be-billet casting azisetyenziswanga kuyo nayiphi na inkqubo yokuphosa apho kukho inkxaso eqinile yokuphosa umjelo, ngenxa yoko zinovelwano kakhulu ukuba zinxitywe. Sisebenzisa i-chrome plating eqinile ukunyusa ubomi beetyhubhu zokungunda. Ubukhulu be-plating buya kulawulwa kuluhlu oluhle kakhulu. Ngokuphathelele ukugquma kweepleyiti zobhedu, ngokusekelwe kwiminyaka yethu yamava, siyakwazi ukubonelela nge-Cr coating, i-Ni-Cr yokwambathisa, i-Ni-Fe yokwaleka ukuhlangabezana nemfuno yabathengi abahlukeneyo ekhaya nakwamanye amazwe.
