Galvanic

INOKS Galvanic has more than 15 years of experience in the field of electro-polishing.

In our galvanic facility we offer you:

ELECTROLYTIC POLISHING - corrosion-resistant products of all shapes and sizes in the standard (Ra 0,6 – 0,8 µm) and FARMA quality (Ra 0,25 – 0,4 µm).

Benefits of electrolytic polishing

  • Cleanliness and quality electrolytically polished surface is the best.
  • Roughness of electro-polished surface is improved and is in standard and quality (Ra 0,6 – 0,8 µm) or in FARMA quality (Ra 0,25 – 0,4 µm).
  • Electro-polished surface is shiny.
  • In the electrolyte polishing we remove all impurities from the base material. All residues introduced into the ferrite forming tools are removed.
  • Leaving only clean stainless steel surface material, which has extend life span.
  • Reduction of micro-surface material of up to 10x, which improves the quality and speed of cleaning materials and reduces water consumption.
  • Electrolytic polishing process is incomparably better than the mechanical polishing of the surface. In the case of mechanical polishing impurities and fat is introduced into the pores of material, which remain in the material for several years after treatment. Therefore, we recommend electrolytic polishing, which remains only pure source material after treatment.
  • The form of the product does not restrict us.

The description of the electrolytic polishing

We have the latest technology of electrolytic polishing stainless materials. We polish all quality stainless materials.The best results, surface quality and corrosion resistance is achieved with the material quality W.Nr. 1.4435.

To surface processing we issue certificate of quality electrolytic polishing, which contains:

  • measured roughness before and after electrolyte polishing
  • measured cleanliness of the surface and measured ferrite
  • measured reflectivity of light from surfaces that are polished electrolytically

Product form does not limit the possibilities electrolytic polishing. In addition, we have developed particular surface treatment of stainless steel and as a combination of electrolytic polishing and bajcanja.

BAJCANJE - chemical etching of stainless components and products without prior treatment, length 6000 mm.

 Optimal corrosion-resistant surface treatment products!

Benefits bajcanja

  • In bajcanju first we remove all impurities from the base material. When material is purged from all impurities from the pores and unreachable edges starting etching all materials introduced into the black residue from forming tools. Thus removed from the surface. This leaves us clean stainless steel surface of the material.
  • Additional chromate film is created in the main surface, which protect all the pores of the material itself. Greatly extending life of the materials.
  • Improves the roughness of the material from a smooth etching.
  • After bajcanju we have a nice steady light gray matte.
  • Especially recommended bajcanje welded stainless components for cleaning impurities around weld itself.
  • Bajcanje is most favorable procedure of surface treatment of stainless materials.

The description of bajcanja
Any mechanical processing such as grinding, means the introduction of tension and impoverishment of chromium, and damages the upper layers of the material.
Heat treatment such as annealing or welding, causes discoloration. This not only affects the appearance, but also the corrosion resistance, because these lesions are composed predominantly of iron oxides that are chemically low resistant to outside influences. You cannot create a passive layer of chromium oxide. In these areas there is corrosion in the following typical forms of pitting ulcers, fissures (corrosive), intergranular corrosion and foreign matter. The surface layer is composed of FeO and is quickly removed by bajcanjem. Active mordant substances mainly consist of acid mixtures and operate in the upper layer of materials in the range 1-3 µm. Oxides such as ferrites and impurities are the first under the influence of acids and are first removed.

Bajcanje provides resistance to corrosion of stainless steel components and is particularly recommended for all stainless steel products, which are exposed to environmental influences. Corrosion resistance of stainless steel is improved because of new surface after bajcanju, which forms a waterproof and chemically resistant passive shield of chromium oxide, which protects the surface from corrosion.

Bajcane surfaces are metallically clean. Material obtained uniformly stabilized matte gray tint and becomes very strong resistance to corrosion.

GALVANIC ZINCING

  • acid galvanic zincing on hangers : size of tub: L= 3500 x W=600 x D= 1300
  • alkali galvanic zincing on hangers : size of tub: L= 3500 x W=550 x D= 1300
  • acid galvanic zincing in drums : wasteful material

Products are zincing, following a complex standard, depending on demand. After pasiviranju they can be electrically coated for improved corrosion resistance.

The alkaline zincing has certain advantages:

  • more uniform coating of zinc over the entire surface,
  • greater application of zinc (up to 35 microns), further treatment (passivation, coating) the same as an acidic zinc).

FOR ALL GALVANIZED PRODUCTS WE PRODUCE APROPRIATE CERTIFICATE!

INOKS Galvanic proves its quality and competitiveness with the certificate of quality BVQi and IPPC permit approvals issued attests on the measurement of film thickness and measurements of roughness.
We have shorten galvanic hands and adapt to customer requests. We provide you with a professional attitude and quality service.
