Surface coatings

As we offer full manufacturing cycle of a part or construction production we use final surface treatment processes: mechanical cleaning, high pressure water washing, shotblasting, priming, wet painting and galvanic coatings.

Mechanical cleaning of metal construction. Conditioning of surfaces with abrasive materials.

High preassure water washing.

Shotblasting – removes mill scale, improves adhesion.

We are equipped with a shotblasting large-size camera L – 21m, W – 5m, H – 4m

Steel shot or grit is used for blasting according to the required roughness.

Most common grit grade is 1-1,7 mm

Priming and painting

 Primer is applied as foundation before painting to reinforce the surface and improve adhesion.

Painting is performed in a large-size camera L – 40 m, W – 4m, H – 5m.

2-component, alkyd and acrylic water base paints can be used.

We offer painting with high-preassure and lower-preassure painting equipment, as ell as electrostatic painting.

Chrome plating. Chrome plating is applied on steel and cast iron.

  • Restoration of worn detail dimensions (shafts). The layer thickness 200-400 µm.
  • Wear-resistant chrome plating (press forms) 25 – 100 µm.
  • Decorative chrome plating (copper, brass, steel parts).

High quality bright nickel-plating (2-layered, with a sub-layer of copper) – decorative and protective-decorative coating.

Coating thickness 10-30 µm for parts from steel and copper alloys.

Galvanizing (or Zinc coating) – a protective coating. It is used for coating of threaded parts, machine parts, etc. Shining galvanizing with colourless passive film. Coating thickness 9-30 µm.

Tinning. Used – for giving a detail antifriction and solderability properties, corrosion protection, sealing of threaded connections.

Coating thickness –  10-20 µm.

Copper bright plating. It used as a decorative coating and as an intermediate layer when nickel plating.

Phosphate chemical coating. Phosphate coating is used for the purpose of pretreatment prior to coating or painting, increasing corrosion protection and improving friction properties of sliding components.

The dimensions of treated parts: max L = 1400 mm, S = 500 mm, F = 700 mm.
