The electroplating process is a function of electrolysis whereby solid metal dissolved in solution bonds and solidifies on surfaces through the application of electric current. Bumpers and parts for electroplating require preparation of visible surfaces by grinding and polishing. It is the time required in the metal preparation stage that is the most significant factor in determining an item's price. Size, shape, contours and surface condition all effect metal preparation time and are taken into account when prices are quoted. Bumpers and parts that have been prepared start the plating process by being attached by copper hooks to the copper rods, which then are placed on electrical contact points mounted on tanks allowing electrical current to flow through the rods. Copper rods loaded with bumpers or parts for plating are moved by hoist through a series of immersions in chemical cleaners and water rinses. Scrubbing and pressure washing remove any remaining contaminants and an acid bath etches the surfaces prior to first 45 minute plating of semi-bright nickel. A second plating of bright nickel is applied for 45 minutes followed by a chrome coating (application), which keeps the nickel-plating from dissolving. Final rinsing, inspection for flaws and packaging completes our work. |
