FOOD SERVICE AND
An Able customer has a shelf used in a food service application and, as such, needed a clean assembly with a
corrosion-resistant surface. The client also desired to remove weld discoloration left behind by manufacturing.
Additionally, the surfaces for this part needed to be cleaned more easily, with minimal food adhesion.
Electropolishing the stainless steel removed the weld discoloration and sub-
Unlike abrasive mechanical polishing, electropolishing is an electro-chemical process ideal for complex parts like
wire shelving. The process strips off a precisely controlled layer of surface metal. In this case, stripping away the
surface metal eliminated the discolored areas and embedded contaminants. Doing so also improved the part’s
corrosion resistance. Electropolishing leaves behind only the native alloy and not a coating, so there is no risk of
flaking, peeling, or cracking. By removing peaks and valleys electropolishing gave the material superior smoothness that makes it easier to clean.
// REMOVE WELD DISCOLORATION FOR WIRE PRODUCTS
After fabricating the various wire weldments for food service and display items, components have
black discoloration at the weld joints. By removing ions from the surface, electropolishing is effective in
removing the outer skin of metal, containing the discoloration in the heat-affected zone.
Products used in the food service and display industry must be sanitary, as
well as attractive, to assure consumer food products are safe.
Electropolishing can reduce bacterial and biofilm formation on the surfaces and produce a decorative finish
that’s necessary for products used for food services and displays.
