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 zokubumba ubhedu, ngokusekelwe kwiminyaka yethu yamava, siyakwazi ukubonelela nge-Cr coating, i-Ni-Cr yokwambathisa, i-Ni-Fe yokwaleka ukuhlangabezana nemfuno yabathengi abahlukeneyo ekhaya nakwamanye amazwe.
