an electropolishing or electroplating system and method for metal conveyor belts is described . as opposed to conventional polishing processes in which the product is guided around rollers which direct the product into and out of an electrolyte bath , embodiments of the present invention pass the product through a housing supplied with a continuous directional flow of electrolyte . thus , the electroplating or electropolishing can be targeted to specific areas of the product , such as the edges and / or the center of a conveyor belt , and straight products can pass through the housing without deformation .
