Electroplating: Electroplating (电镀)
A process that deposits a thin metal layer onto zipper parts to provide colour, gloss and corrosion resistance. Cleaning, activation, bath chemistry, current density and plating time all affect adhesion and thickness uniformity. Poor plating leads to peeling, blistering and early corrosion, especially at edges and recesses. Thickness and adhesion are checked, and finished parts are evaluated with salt spray and abrasion tests.
