Why Electropolish?
Purification: As mentioned previously, electropolishing restricts bacteria growth by removing hydrogen throughout the metal. Unlike a coating, an electropolished surface cannot flake off or chip, which is important for the food industries, pharmaceutical processing, high vacuum assemblies and pure gas/water systems, such as reverse osmosis. Electropolishing also removes free iron which cause metals to rust. By removing the free iron and adding the hard chromium layer electropolishing leaves behind you are left with corrosion resistant alloys.
Adhesion: Electropolishing improves the adhesion of paint, adhesives or plasma. Oxides oil corrosion and organic debris on the metal surface make adhesion difficult. After electropolishing, the bonding ability during welding or soldering is improved greatly, do to the restriction of outgassing once impurities are removed.
De-stressing: Springs and small stamping's subjected to thousands or millions of cycles fail prematurely due to metal fatigue. By removing surface metal, electropolishing actually helps solve metal fatigue problems caused by surface cracks, nicks, scratches and fabrication stresses. The process removes the surface skin and stresses and reduces, or eliminates imperfections caused by heat treating, decarburization, microscopic scratches, tool marks and grinding checks. This increases the part's life cycle while imparting a smooth, bright, deburred surface.
Every electropolishing job is different, and each has it's unique challenges.
The collective experience of our electropolishing technicians is so broad that they're equipped to handle any unexpected challenge.
