Electrolytic zinc plating on a cell surface

Electrolytic zinc plating is a common method of coating steel. The coating achieved during the treatment process provides reasonable corrosion protection and a pleasing appearance at low cost. Thanks to the different passivations used, it is possible to achieve parts with different colour and corrosion resistance. Electrolytic zinc plating is also often used under paint to improve corrosion resistance and paint adhesion.

Electrolytic zinc plating options

  • Max dimensions of the item to be covered: 3,1 x 0,4 x 1,2 m
  • Max weight of galvanised part: 100 kg
  • Post-processing: blue, yellow and black passivation

Electrolytic zinc plating in a drum

Electrolytic zinc plating is a common method of coating steel. The coating achieved during the treatment process provides reasonable corrosion protection and a pleasing appearance at low cost. Thanks to the different passivations used, it is possible to achieve parts with different colour and corrosion resistance. Smaller parts can be galvanised using the drum method.

Electrolytic zinc plating options

  • Max length of detail to be covered: 180 mm
  • Max weight of galvanised part: 300 g
  • Post-processing: blue passivation

Electrolytic nickel plating on the cell surface

Nickel plating is used in the electronics and electrical industries. The surface of the detail to be covered remains glossy.
The main materials covered are steel and brass.

Electrolytic nickel plating options for cells

  • Max dimensions of the item to be covered: 2,8 x 0,3 x 1,2 m
  • Max weight of the workpiece: 100 kg

Electrolytic nickel plating in a drum

Nickel plating is used in the electronics and electrical industries. The surface of the detail to be covered remains glossy.
The main materials covered are steel and brass.

Electrolytic nickel plating in the drum

  • Max length of detail to be covered: 180 mm
  • Max weight of the piece to be fired: 300 g

Electrolytic chromium plating

Chrome plating is the process of coating a piece with a nickel base. As a result, gloss and corrosion protection of the substrate is achieved. The nickel/chrome (Ni/Cr) surface is strong, good looking and gives reasonable protection to the substrate.

Electrolytic chromium plating options

  • Max dimensions of the item to be covered: 2,8 x 0,3 x 1,2 m
  • Max weight of chrome plated part: 100 kg

Electrolytic tinning

Electrolytic tin plating improves the corrosion resistance of the part, as well as its electrical conductivity, and adds machinability and solderability. Due to its low transfer resistance, it is mostly used in the electrical and electronics industries. Under the tin coating, a nickel layer (3-6µm) is used to prevent the substrate from mixing with the coating.

Electrolytic tinning options

  • Max dimensions of the item to be covered: 2,8 x 0,3 x 1,2 m
  • Max weight of part to be tinned: 100 kg

Chromate plating

Chromate plating with Surtec 650 is a chemical process that protects the aluminium surface from oxidation while maintaining electrical conductivity. After treatment, the surface remains matt.

Chromate options

  • Max dimensions of the workpiece: 2,2 x 0,25 x 1,0 m
  • Max weight of chrome plated part: 100 kg

Stainless metal passivation

Passivation of stainless steel is a chemical process that removes oxide layers, welding residues and machining marks from the surface of the part. After treatment, the surface of the piece remains greyish and satin matt. Passivation increases corrosion resistance and homogenises the appearance of the part.

Stainless metal passivation options

  • Max dimensions of the workpiece: 2,8 x 0,3 x 1,2 m
  • Max weight of passive part: 100 kg
