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.
