Ingcaciso yeMveliso
Ezi ngcingo zokumelana ne-enameled ziye zasetyenziswa ngokubanzi kwizixhasi eziqhelekileyo, iimoto
iinxalenye, izixhasi zokujija, njl.njl. usebenzisa i-insulation processing ngokufanelekileyo kwezi zicelo, ukuthatha inzuzo epheleleyo yeempawu ezahlukileyo ze-enamel coating.
Ngaphaya koko, siya kwenza ukugquma kwe-enamel yocingo lwentsimbi exabisekileyo njengesilivere kunye nocingo lweplatinam ngokomyalelo. Nceda usebenzise le mveliso-nge-odolo.
