Chofanana chowala pamwamba ntchito ngati galasi ndi electroplated pamwamba pa gudumu likulu. Kuwala kowala kwa gudumu likulu ndi electroplated mu vacuum chilengedwe. Ma electroplating a ma wheel hubs amagwiritsa ntchito ukadaulo wapamwamba kwambiri padziko lonse lapansi wokutira wa ufa ndi ukadaulo wa maginito wa vacuum pokonza ma wheel hubs. Maonekedwe a ukadaulo uwu ndikusintha kuwononga chilengedwe komanso njira zotsika mtengo zama electroplating, ndikupanga zinthu zamtengo wapatali popanda kuwononga chilichonse komanso kupanga -mwachangu kwambiri. Poyerekeza ndi zokutira zopopera zakunja, vacuum electroplating ya ma wheel hubs imakhala ndi zomatira zolimba, moyo wautali wautumiki, ndipo palibe kusenda kapena kupenta; Poyerekeza ndi electroplating ndi madzi, vacuum electroplating imalola ogwiritsa ntchito kusankha mitundu yawo ndikupanga mtundu uliwonse womwe angafune, mosiyana ndi electroplating yokhala ndi zoyera ndi zakuda zokha.
