Imela yenziwe ngezinto ze-tungsten carbide, kodwa ezinye izinto zikhoyo. Njenge-HSS, 9CrSi, Cr12Mo, VW6Mo5, Cr4V2, i-alloy eqinile, njl. Izinto eziluhlaza ziphathwa ngobushushu, i-vacuum iphathwa, kwaye ubunzima buphezulu. Unyango olushushu kwifektri yakho ukuqinisekisa ukuzinza kwemveliso. Umphetho wemela ubukhali, ugudileyo, ubukhali kwaye uhlala ixesha elide, izixhobo zokulungisa ezichanekileyo eziphuma kumazwe angaphandle ziyakwazi ukujongana neemveliso ezahlukeneyo ezingezizo ezisemgangathweni ukuqinisekisa ukuchaneka kweemveliso.
