Various Ways to Clean Surfaces

Degreasing - The Most Gentle Method

This is a suitable process when minor fouling needs to be removed and a high degree of dimensional accuracy is required, while at the same time maintaining the gloss level and surface structure.

The aim of degreasing is to achieve a clean surface so that the subsequent surface finishing can be carried out to a high standard of quality.

Specific features

  • No abrasion
  • Surface structure and glossiness are preserved


Ultrasonic Degreasing - For Stubborn Fouling

In contrast to conventional degreasing, this process can be used to remove even stubborn fouling. The effect on the surface character is minimal.

Specific features

  • No abrasion
  • Little change in surface structure and -glossiness
  • Removes stubborn fouling


Pickle Degreasing - Bad for Oxide Layers, Good for Electroplating

The process leads to a volatile removal of material and thus to a slight matting of the surface; the glossiness is preserved to some degree. Pickle degreasing is used when fouling which is difficult to remove or slight oxide layers have formed on the surface. It is also used to activate surfaces for subsequent galvanic treatments.

Pickle degreasing can only be used for aluminium.

Specific features

  • Removes very stubborn fouling and oxide layers.


Decorative Pickling  - When Other Processes Prove Ineffective

A material removal of between 0.05 mm and 0.20 mm results in a uniform matting of the surface. It is the strongest chemical process for the removal of fouling and mill scale. This process is ideal when matte surfaces are desired and dimensional accuracy is not an issue.

Special features

  • Removes extremely stubborn fouling and oxide layers
  • Uniform matting


Shining - We Make Shiny Surfaces Shine Even More

The gloss level of certain aluminium alloys can be visibly increased by a chemical process. This results in mirror-like, highly reflective surfaces that differ significantly from their original state in terms of glossiness.

Can only be used for aluminium, provided that heavy material removal is not an issue.

Special features

  • Higher gloss level / material appears more valuable
