Profile: Sinha Electro Chemical Plant is specialized in zinc plating. The zinc plating involves the electrolytic application of zinc by immersing clean steel parts in a zinc salt solution and applying an electric current. This process applies a layer of pure zinc that ranges from a few microns on cheap hardware components to 15 microns or more on good quality fasteners. Rack plated parts are fixtured to a coated metal rack for processing. Parts may be attached by spring fingers, wire or screws depending on part size, configuration and weight. This rack plating process allows parts to be plated all over or selectively plated by plugging or masking locations, where plating is not required. Professional rack plating provides the ability to plate larger parts that are dipped into a bath to allow exposure to plating current. Products are typically affixed to a production rack that has up to a 20-foot capacity to handle any zinc-plating requirement.
