In these machining processes, the material is removed manually or mechanically using appropriate abrasives and rubbing motions to achieve the desired surface structure.
Particularly during the brushing of metal or aluminium, fine-, medium- or coarse-textured surfaces can be produced for high-quality optics and further refined in a subsequent process, e.g. anodising.
According to DIN 17611:
– Without pre-treatment E0
– Grinded E1
– Brushed E2
– Polished E3
– Grinded and brushed E4
– Grinded and polished E5
– Special stained E6
– Chemically polished E7
– Polished and chemically polished E8
In blasting, the surface treatment is carried out using different blasting media that are directed onto the material at high speed, e.g. by means of air. This densifies the material and at the same time strengthens the surface. This process can also be used to clean, chip, matt and finish surfaces, among other things.
According to DIN 17611:
– Blasted E9
Possible structures:
– Fine blasting pattern S10
– Medium blasting pattern S11
– Coarse blasting pattern S12
We achieve high gloss levels through the process of laser polishing.
By removing thin layers of the surface, the smallest burrs, particles, irregularities and impurities are removed. This makes it possible to achieve high strength and lower adhesion as well as the pure and shiny results for the material.
According to DIN 17611:
– Polished E3
– Grinded and polished E5
– Polished and chemically/electrolytically polished E8
We have a factory-owned anodising plant that can support you with the following finishing processes:
In addition, various forms of pre- and post-treatment are possible, for example brushing, grinding, blasting, polishing, special pickling and lasering.
Using our own powder coating facility, we coat components with a choice of over 210 RAL colours, which we deliver just-in-time. For special requirements, we provide the surfaces for example with anti-stick or anti-fingerprint coatings.
For the visual labelling of functional components and other products, e.g. with logos, symbols or lettering, we use various processes for individual decorative and functional coatings:
Aluminium, sheet metal, stainless steel and steel:
For the required substructure of metal components and metal foils, we back-inject them with the required plastics.
We design and manufacture the plastic injection moulding tools required for this ourselves in order to avoid distortion due to shrinkage and different linear expansions. Furthermore, we integrate the desired electronics or lighting elements during back injection moulding.
We join components using a wide variety of methods. In bonding, we use liquid adhesives, adhesive tapes and also adhesive die-cuts, which we apply manually or robotically. Optionally, different types of pre-treatment are possible, including plasma, primer, scarfing or pyrosil as well as different rapid curing methods (UV light, infrared, heat radiation).
We manufacture a wide range of different products, including fan wheels and components as part of assemblies, in our own plastic injection moulding shop with machines up to 300 t clamping force.
We manufacture the corresponding moulds and injection moulding tools ourselves.

FAQs
Please take into account that our production is geared towards medium to large series production. We are therefore unable to process requests for very small quantities for economic reasons.
We ask for your understanding that we cannot consider requests from private individuals of any kind.
