INDUSTRY:

Food/Beverage

MFG/METHOD:

Metal forming and welding

ALLOY:

304 & 303 stainless steel

PROBLEM:

This assembly in final use was constantly immersed in cooking oil and in contact with food products. Fabricated from multiple alloys of stainless that had been perforated and spot welded, the final assembly had numerous points of surface contamination. The customer looked into electropolishing in order to improve corrosion resistance and cleanability.

SOLUTION:

The size and design of the assembly required specialized tooling in order to finish all surfaces uniformly with little dimensional change. By immersing the entire assembly into the polishing bath, all surfaces were processed simultaneously. Removal of surface metal cleaned all weld areas and perforations. In addition to leaving a smooth, easy to clean surface, the resultant shiny surface improved the appearance of the part.
