Ipuleti elifakwe umbala liphinde libizwe ngokuthi i-coating plate, ipuleti lensimbi lombala, lisekelwe kukhoyili yensimbi (ipuleti eligoqiwe elibandayo, ipuleti elinothayela elishisayo, ipuleti le-aluminium, ipuleti le-aluminium ephezulu, ipuleti lensimbi engagqwali, njll.) njengento eyisisekelo, enamathela ebusweni noma laminating ezihlukahlukene enamathela eziphilayo noma ifilimu plastic.Ngenxa yokuthi iqedwa kukhoyili yokuhlanganisa i-metallurgical factory surface, ingacutshungulwa ngokuqondile ngabasebenzisi ibe yimikhiqizo, eyaziwa nangokuthi ikhoyili efakwe ngaphambili.
