Bright Dip

Manufacturing Process Degreaser Jerry At Line

Bright dip is a chemical process that brightens metal and removes surface scale and oxidation, leaving the part clean and uniformly bright with minimal tarnish resistance. The degree of brightness is dependent on the type of alloy, as well as the surface finish of the part. We bright dip copper and copper alloys.

Chromating

Chromating provides a refined appearance and increased corrosion resistance, along with greater resistance to fingerprint staining. Chromating is an excellent pre-paint base, increasing paint adhesion and imparting color to metal for coloring effect or identification. Chromates are a soft coating that, when wet, are easy to scratch. However, once dry, the coating becomes more durable with age. Hexavalent chromates are damaged by heat over 150 degrees. We chromate directly on zinc die castings and zinc plated parts. Corrosion resistance is increased with the use of chromates and sealer:

Colors/Sealers:

  • Clear (bright blue) Trivalent Chromate (hex-free)
  • Clear (bright blue) High Corrosion-resistant Trivalent Chromate (hex-free)
  • Yellow (iridescent) Dichromate
  • Gold Dye (used over Trivalent Chromate)
  • Post Chromate Silicate Sealer

Please view our Environmental page for more information about trivalent/hexavalent-free chromates, in addition to RoHS, ELV, and EEE compliant finishes.

Degreasing

Degreasing is offered as a pre-plate cleaning where necessary or as a separate service. We utilize a vapor/liquid phase trichloroethylene degreaser.

Passivation

Passivation is the use of an acid solution to render the surface of stainless steel in a “passive” state that enhances its corrosion resistance. Milwaukee Plating offers nitric acid passivating by rack or basket (bulk).

Polish and Buff

Our services include polishing, buffing and brushing of various base metal parts. These processes are used to create an improved or modified surface for plating.
