Finishing

Whatever you encounter in this world works through its outward appearance. And because the first impression is so crucial, we have elevated the treatment and refinement of the surface to an art. This means an upgrade of the components and products - from a technical as well as an aesthetic point of view.

We offer you a unique range of surface finishes: From mechanical processing with different sanding patterns, structures and degrees of gloss to various types of coating and materials to the color palette we have developed ourselves with standard colors, special colors and contemporary pastel tones.

Technical anodizing

The anodizing process is the creation of an oxidic protective layer through anodic oxidation in the uppermost aluminum zone. A 5 to 25 μm thin, resistant hard layer is created that protects against corrosion.

Hand anodization, Process dimensions 2500 x 700 x 500 mm

Surface quality according to DIN 17611 / pre-treatment variants before anodizing

E0 – Degreasing
Without mechanical or chemical pre-treatment. For surfaces, who are not in the spotlight. (Scratches and defects remain visible)

E1 – Grinding
Ground decorative surfaces with a clearly aligned structure (micrograph) and a somewhat matte-dull appearance.

E2 – Brushing
Brushed, matt-gloss surfaces with an easy-to-maintain, fine structure (brush strokes).

E3 – Polishing
Polished, shiny, bare surface for indoor products.

E4 – Grinding and Brushing
Brushed and grinded consistent surface. Mechanical surface defects are eliminated.

E5 – Grinding and Polishing
Grinded and polished surface with a smooth shiny physical appearance. The best removal of surface defects

E6 – Pickling
Chemical pre-treatment (alkaline solution) with a homogeneous material removal and a matt finishing. Mechanical surface defects are compensated (but not completely eliminated).

E7 – Electrochemically polishing
After degreasing the surface in a non-caustic cleaning agent, the surface is treated with a special chemical process to give it a high gloss finish. Surface defects are only eliminated to a limited extent, and the effects of corrosion can become visible.

Color anodizing

A combination of the anodizing process with coloring (absorption dyes and alternating current coloring) offers a wide range of design, functional and aesthetic options for creating an attractive surface (e.g. for cases, dials, front panels, jewelry, etc.).

Brushing and Grinding

Brushing is a technical process used for deburring, fine grinding or cleaning of materials. Complete surfaces for aluminium, steel or stainless steel - whether highly polished surfaces in watchmaker quality or precisely brushed medical instruments.

Grinding is an abrasive manufacturing process for processing surfaces with abrasives. The result is metallically pure surfaces free of residues (further processing) and uniform micrographs with high dimensional and shape accuracy and low waviness/roughness.

Scotching and polishing

Scotching is a technical process that was specially developed for the refinement of stainless steel surfaces and creates a fine line pattern. Mainly aluminum and stainless steel can be produced in a wide variety of gloss levels.

Polishing is a smoothing fine machining process for a wide variety of materials, which achieves a smoothing effect through plastic deformation and leveling of the roughness peaks of the surface structure and/or through - depending on the type of polish - least to small material removal.

Blasting

Blasting is a structure-generating process for matt or satin-gloss surface structures. Small surface imperfections in the material can be concealed by the abrasive effect of stainless steel balls, which hit the material with the help of air pressure.

Pickling and Passivation

Pickling is chemical etching of metal surfaces using an aggressive, alkaline solution to remove applied metal layers or to get an oxide-free surface (activation of the base metal for further coating).

Maximum measurements 4000 x 1000 x 500 mm

Passivation is the chemical treatment of surfaces to increase corrosion protection with excellent conductivity. Positive for subsequent painting and powder coating processes, to reduce fingerprint sensitivity and to change the appearance (gloss, color).

Maximum measurements 4000 x 1000 x 360 mm

Hard anodizing

Hard anodizing (or hard coating) is the electrolytic oxidation of semi-finished aluminum products, which improves a surface in such a way that high demands are made in terms of wear resistance and high corrosion protection.

At temperatures of 0°C, alloy-dependent layer thicknesses of up to 100 μm develop, which have a greater surface hardness than stainless steel. Above all, housings, bolts, guides and mostly components for technical purposes that are subject to high loads are subjected to this process.

This ceramic-like layer is not conductive and also serves as electrical insulation. Depending on the alloy composition and layer thickness, we also color hard anodized surfaces for you.
