In its broadest definition, electropolishing is a process which brightens stainless steel. Summa Processing is the best method for this in terms of uniformity, luster and controlled metal removal.
Chromium and nickel, which are components of stainless steel, are electrolytically drawn to the surface. In essence, the effect is very similar to chrome plating, except that there is no adhesion to be concerned with. The layer is a homogenous constituent of the metal and cannot delaminate or peel. This nickely chromium mono-oxide layer is extremely corrosion resistant.
Standard types of elecropolishing do not remove metal uniformly. The resulting dimensions are usually out of blueprint tolerance. However, this is not a problem with Summa Processing due to the uniform rate of metal removal. Removing 0.0005" from a surface and maintaining a tolerance of plus or minus 0.0002" is readily achievable.
Another major benefit of Molectrics Power Kleen 500 is its low voltage and low temperature operation. This equates to minimal fuming and low energy costs. Also, there is no other bath available with as long of a life or with ease of rinse water disposal.
The other results of Summa Processing are achieved simultaneously. While the surface of the metal is being brightened, it is also being refined and passivated. The metal is also being deburred and purged of hydrogen. The advantages of Summa Processing are clearly evident.
