Scientific Workshop - Electroplating Deparment

The task of electroplating is the fine and surface treatment of metals of all kinds.

Electroplating of metals

(steel, brass, and copper)

  • Copper plating
    Electroforming, e.g. hollow conductors
  • Nickel plating
    Bright nickel plating - hard, wear-resistant coating, good corrosion protection
  • Gold plating
    Hard bright gold plating - hard, wear-resistant coating, highly conductive contacts
  • Zinc plating
    Bright zinc plating - very good corrosion protection through subsequent chromating in
    Colors: colorless, yellow, black

Surface treatment of aluminum

  • Anodizing
    - the anodized layer is very smooth, hard, and electrically insulating
  • Coloring of the anodized layer
    - natural, black, yellow, red, blue, turquoise, green, bronze
  • Yellow chromating of aluminum
    - electrical conductivity remains (similar to anodizing process)
    - corrosion protection is increased
    - excellent adhesion base for paints and adhesives
  • Galvanizing of aluminum
    - the cleaned aluminum surface can be galvanically coated with all metals after a special chemical pretreatment

Cleaning of metallic workpieces

  • Degreasing
    - Hot degreasing bath with universal cleaner
    - Cleaning in an ultrasonic bath
  • Pickling
    - Derusting and descaling of steel
    - Deoxidizing
    - Descale stainless steel welds
  • Sandblasting
    - Removing rust, paint residues, and scale
    - Matting of metal, plastic, and glass


Hollow conductor production for use in electrical engineering

The core of the waveguide is made of aluminum. The aluminum core is electroplated with a copper shell about 3mm thick, and then the aluminum core is etched out in a solution of caustic soda.
