Waya wa enamelled ndiye zida zazikulu zama injini, zida zamagetsi ndi zida zapakhomo. Makamaka m'zaka zaposachedwa, makampani opanga magetsi apeza kukula kosalekeza komanso kofulumira, ndipo kukula kwachangu kwa zida zapakhomo kwabweretsa gawo lalikulu pakugwiritsa ntchito waya wa enamelled. Pambuyo pake, zofunikira zapamwamba zimayikidwa patsogolo pa waya wa enamelled. Choncho, n'zosapeŵeka kusintha kapangidwe kazinthu za waya wa enamelled, ndi zipangizo zofananira, teknoloji ya enamelled, zipangizo zamakina ndi njira zodziwira ziyeneranso kupangidwa ndi kuphunzira.

Ndiye pali ubale wotani pakati pa waya wa enameled ndi makina owotcherera? M'malo mwake, makina opangira waya opangidwa ndi enamelled amagwiritsa ntchito madzi ngati mafuta kuti azitha kutulutsa madzi kudzera mu njira ya electrochemical kupanga haidrojeni ndi okosijeni. Amayatsidwa ndi mfuti yapadera yamoto wa haidrojeni ndi mpweya kuti apange lawi la haidrojeni ndi mpweya. Peeling kuwotcherera ikuchitika pawiri kapena angapo zingwe waya enamelled popanda peeling zina. Chifukwa kutentha kwa haidrojeni ndi lawi la okosijeni ndi lokwera kwambiri mpaka 2800 ℃, cholumikizira cha zingwe zingapo za mawaya enamelled chimalumikizidwa mwachindunji ndikuwotchedwa mu mpira pansi pa lawi lamoto, ndipo cholumikizira chowotcherera chimakhala cholimba komanso chodalirika. Poyerekeza ndi miyambo kukhudza kuwotcherera ndi malo kuwotcherera, izo ali ubwino osiyanasiyana ntchito, moyo wautali utumiki, palibe utsi wakuda, kuwotcherera odalirika ndi zina zotero.
