DE Whatever you encounter in this world has an effect through its external appearance. And because the first impression is so important, we have elevated the processing and finishing of the surface to an art form. This means an upgrade of the components and products – both technically and aesthetically. We offer you a unique range of surface refinements: From mechanical processing with different grinding patterns, structures and gloss levels to various types of coatings and materials to the color palette we developed ourselves with standard colors, special colors and contemporary pastel shades.

Technical anodizing
The Eloxal process (anodization) is the creation of an oxide protective layer through anodic oxidation in the top aluminum zone. A 5 to 25 μm thin, resistant hard layer is created that protects against corrosion.
- Semi-automatic anodizing system, processing dimensions 4000 x 1000 x 500 mm
- Trade oxal plant, processing dimensions 500 x 700 x 500 mm
- E0 – Degreasing
Without mechanical or chemical pretreatment. For surfaces that are not in the foreground (scratches and flaws remain visible). - E1 – Grinding
Grinded decorative surfaces with a clearly directed structure (grind pattern) and a somewhat dull matt appearance. - E2 – Brushes
Brushed matt-glossy surfaces with an easy-to-maintain, fine structure (brush strokes). - E3 – Polishing
Polished shiny, bare surfaces for indoor products. - E4 – Sanding and brushing
Sanded and brushed uniform shiny surface. Mechanical surface defects are eliminated. - E5 - Grinding and Polishing
Grinded and polished with a smooth shiny "classy" appearance. Best elimination of mechanical surface defects. - E6 – Staining
Chemical pre-treatment (alkaline solution) with even material removal and a matt shine. Mechanical surface defects are compensated for (but not completely eliminated). - E7 – Chemical shine
After degreasing the surface in a non-corrosive cleaning agent, the surface is given a high shine by treatment in a special chemical process stage. Surface defects are only eliminated to a limited extent and corrosion effects can become visible.
Maximum dimensions: 800 x 900 x 600 mm.
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 possibilities with an attractive surface (cases, dials, front panels, jewelry...). Processing sizes up to 700 x 700 x 500 mm are possible.
Brushing and grinding
Brushing is a technical process that is used for deburring, fine grinding or cleaning materials. Complete surfaces for aluminum, 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) as well as uniform micrographs with high dimensional and shape accuracy and low waviness/roughness.
With our Lissmac SMW535 we can perfectly grind, satinize and, in combination, process aluminum sheets with a maximum width of 1250mm (medium format) in a highly decorative way.

Scotching and polishing
Scotch is a technical process that was specifically developed for refining 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 finishing 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 - very small to small material removal.
Blasting
Blasting is a structure-generating process that uses the abrasive effect of ferrite-free balls accelerated in an air stream.
Matte or silky-glossy surfaces are specifically created using blasting technology and surface defects in the material are concealed.

Pickling and passivation
Staining is a chemical etching of metal surfaces using aggressive chemicals (alkaline solution) to remove applied metal layers or to obtain an oxide-free surface (activation of the base metal for further coating).
Processing dimensions 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, for reducing fingerprint sensitivity and for changing the appearance (gloss, color).
Hard anodizing
Hard anodizing (hard anodizing or hard coating) is the electrolytic oxidation of semi-finished aluminum products, which creates a hard and extremely abrasion-resistant protective layer as protection against wear and corrosion. At temperatures of 4 - 7°C, layer thicknesses of up to 100 μm are created (depending on the alloy), which have a greater surface hardness (HV > 200) than stainless steel. These hard anodized layers are mostly used for technical purposes such as bolts, bearings, housings, guides, control valves, machine components, highly stressed hinges and aluminum profiles. As a ceramic layer, this layer conducts poorly and therefore also serves as electrical insulation. Depending on the alloy composition, we can also color hard-anodized surfaces for you.
