Electropolishing is a chemical surface-finishing technique, by which metal is electronically removed, ion by ion, from the surface of a metal object. The primary objective is to minimize micro-roughness, thus dramatically reducing the dust or dirt or product residues adhering and improving the cleanability of the surfaces. Electropolishing is also used for deburring, brightening and passivating.
The process exposes an undisturbed, metallurgically clean surface. Possible unwanted effects of mechanical surface treatment – mechanical and thermal stress, embedding of particles and surface roughening – are avoided or reversed. The inherent corrosion-resistance of a given stainless steel grade is fully used. For these reasons, electropolishing has become a common treatment for stainless steel in industries in which corrosion-resistance and cleanability requirements are particularly high. Typical applications are found in pharmaceutical, biochemical, hospitality, food-processing, automobile and food processing industries.
Since 1991, SMEE has been providing metal finishing services to a variety of industries. Now our electropolishing service is suitable for all kinds of stainless steel products, providing a number of benefits that make parts last longer, perform better and maintain a clean, like-new appearance.
