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. — Semi-automatic anodizing plant, processing dimensions 4000 x 1000 x 500 mm — hand anodizing plant, processing dimensions 2500 x 700 x 500 mm

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. This ceramic-like layer is not conductive and also serves as electrical insulation. Maximum measurements 2750 x 700 x 300 mm

Screen printing (traditionally: serigraphy) is a printing process in which the printing ink is applied to the material through a fine-meshed textile fabric using a wiper through-printing process. The mesh openings are color-impermeable (closed) or open like a stencil. The color application can be varied through different fabric fineness and high color layer thicknesses can be achieved. Half-print machine, Max. 800 x 700mm Furthermore, we set up table screens for special requirements for you.

Weather resistance, abrasion resistance and light fastness are among the very good end properties of the 4-color system anodised digital print. MotionJet Pro 810+, Maximum measurements 800 x 1300mm and Resolution of 1440 x 1440 DPI

CNC 5 axis milling of aluminium, brass, steel, plastics etc. at our DMG ecoMill 70 (workspace XYZ 750 x 600 x 520 mm), DMG DMU 75 Mono-Block (workspace XYZ 750 x 650 x 560mm) and Elumatec SBZ-151 (workspace XYZ 9000 x 1150 x 715 mm)

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.). Maximum measurements 700 x 700 x 500 mm

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. Hand blast cabinet MHG Maximum measurements 2000 x 1000 x 1000 mm Blast cabinet Maximum measurements 400 x 400 x 200 mm

UV printing is a direct and digital printing in which the applied ink is hardened by ultraviolet light. The advantages lie primarily in the flexibility of the printing materials and that, in contrast to sub-anodized printing, it can print white. Due to the printing structure in layers, images and fonts can be touched, such as the braille. With our Mimaki UJF-7151plus we can print an area of 710 x 510 mm with a resolution of 1,200 dpi.

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.

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. — Lissmac SMW535: max. width 1250mm (grinding, satin finishing and highly decorative processing in one operation) — Kuhlmeyer type ZBS3: max. 4000 x 750 mm — Metallkraft MBSM 2000 ZB: max. 2000 x 750 mm
