Plating is a type of coating in which a metal is deposited on a conductive surface. corrosion-resistant properties, enhanced solderability, hardness, and reduced friction, including Nickel Plating, Silver Plating, Gold Plating, Chrome Plating, Zinc Plating, and Tin Plating.
Plating is a surface finishing process where a thin layer of metal (such as nickel, chrome, or gold) is deposited onto the surface of a workpiece using an electric current.
Utilizes rotating cutting tools for high-precision machining of flat surfaces, curves, and complex parts, ideal for mold making, aerospace, and automotive industries.
Uses rotating workpieces and cutting tools for efficient machining of cylindrical components, widely applied in shafts, discs, and precision parts manufacturing.
Enables multi-angle precision cutting, reducing setups and machining complex surfaces, perfect for high-end aerospace, medical devices, and precision mold manufacturing.
