Brush plating is an electroplating technique using a fabric-coated graphite tampon flooded with electrolyte, which is hand applied to parts of varying sizes. It uses systems to electroplate, anodize, and electropolish localized areas on both OEM components and parts that need coatings for repair and dimensional restoration. Brush plating requires different hand-held tools for each different solution in the operation.
Brush plunger is designed to operate in wells with sand and solids suspended in the liquids. The brush does not deteriorate from the mandrel during flow due to the dual restraint system applied to the brush fiber. The brush also flexes, preventing solids from accumulating in the body and allowing the plunger to work well in tubing with irregular or tight spots.
