Polishing
Metal polishing machines are specialized tools used to achieve a smooth, high-gloss finish on metal surfaces. They come in various types, including belt grinders, disc finishers, and buffer machines. These machines utilize abrasive materials or polishing compounds, along with rotating wheels or belts, to remove imperfections and create a polished surface.
Chrome Plating
Chrome plating is an electroplating process in which a thin layer of chromium is applied to a metal or plastic surface to enhance appearance and improve properties like corrosion resistance, hardness, and wear resistance. It comes in two main types: decorative chrome, which provides a shiny, mirror-like finish and is typically applied over nickel, and hard chrome (industrial chrome), which is thicker and used to improve durability and reduce friction in machinery.
Nickel Plating
Nickel plating is a process in which a thin layer of nickel is electroplated onto a metal or plastic surface to improve corrosion resistance, enhance appearance, and increase wear and hardness. It can be used as a decorative finish or as a functional layer, often serving as a base coat for chrome plating. There are two main types: electroplating, which uses an electric current to deposit nickel, and electroless plating, which relies on a chemical reaction without electricity.
Copper Plating
Copper plating is the process of electroplating a thin layer of copper onto the surface of a metal or plastic object to improve conductivity, corrosion resistance, and adhesion for subsequent layers like nickel or chrome. It is commonly used in electrical components, circuit boards, and as an undercoat in decorative or industrial plating systems. Copper plating provides a smooth, conductive surface and can fill in minor surface imperfections.
Zinc Plating
Zinc plating is the process of applying a thin layer of zinc to the surface of metal objects, usually steel or iron, to protect them from corrosion and rust. The zinc acts as a sacrificial coating, corroding in place of the base metal, thereby extending the lifespan of the product. It is commonly used in automotive parts, fasteners, hardware, and household appliances. The process involves cleaning the metal, immersing it in a zinc salt solution, and using electrolysis to deposit the zinc layer.
