We Now offer Electropolishing
Electropolishing – Overview
The Electropolishing process cleans and polishes metal in a special electrochemical solution. An electrical current passes through a chemical bath, dissolving a small amount of smear metal from the surface, leaving a smooth, shiny finish. The current is greatest on the outside edges and corners of parts, which are left especially smooth. Increasing the process time will remove more amount of metal. Holes can be enlarged, threads can be rounded and sharp edges or burrs can be reduced.
Electro polishing can be performed on stainless steel. Electro polishing is an excellent finishing process for fine parts because no vibrating or tumbling is involved. Due to the part being bathed in oxygen, hydrogen is removed from the surface, thereby acting as a stress relieving anneal. In addition, the electropolished surface, being free of hydrogen greatly reduces the possibility of bacterial growth. Electro polishing is the best choice when contamination cannot be tolerated.
Applications include: food processing and food handling equipment
Electropolishing’s primary function is to improve parts cosmetically. It cleans, polishes and brightens stainless steel in a way that no other process can and also removes small burrs. The results, easily visible to the naked eye, make extra finishing operations and costs unnecessary. Intricate components requiring microfinishes are greatly improved. As a result, friction, leakage and wear problems can be eliminated. Corrosion Resistance Stainless steel, although known for its excellent corrosion resistance, may still corrode when impurities are left on the surface of the metal.
Electropolishing dissolves a minute layer of the part’s surface metal. Impurities are removed and the surface is left brighter, ultra passive and protected from rust.
