Below is a list of Parts Washers manufacturers from Hillside, New Jersey. Parts washers are one of the last steps in the parts manufacturing process; they are designed to clean, degrease and dry mass quantities of small or large parts in preparation for surface treatment and distribution. Newly machined, forged or fabricated products are usually coated in oils, chemicals, burrs, abrasive dust, debris, paint and other residue left over from the fabrication process. Finishing coatings such as zinc and electroplating are not effective if they are applied on a dirty surface.
