Precision manufacture of complex milled components from unfilled and fibre-reinforced engineering plastics — with high repeatability and consistent machining quality.
In CNC milling, material is removed by rotating tools along precisely defined machining paths — ideal for components with complex contours, pockets, hole patterns, grooves, flat surfaces and free-form geometries.
Milling plastics requires a deep understanding of the material: thermal expansion, stiffness, chip formation and springback vary significantly between polymers and directly influence achievable tolerances. We therefore consider geometry, material, fibre orientation, tolerance requirements and the application environment together.
Housings, covers, brackets, insulation components, fixtures and textured functional surfaces — including custom parts with tight tolerances and specified surface finishes.
Precise machining of complex geometries in engineering and high-performance plastics — in few setups, with high positional accuracy.
Intelligent clamping solutions and automated processes lay the foundation for cost-effective small-batch and series production.
Tailored strategies for carbon- and glass-fibre reinforced polymers: correct tools, parameters and clamping for abrasive composites.
Vertical machining centre for precision milling of engineering plastics.
Rigid VMC platform for tight-tolerance component and fixture work.
Large-format routing of plates, panels and composite sheet material.
Multi-face machiningMachined from solid on 5 axes — sealing faces, bores and cable entries held in true position across setups.

StructuralLoad-carrying plates and angles with tight hole-position tolerance for repeatable assembly.
Internal channelsIntersecting bores and internal passages, deburred and cleaned; leak testing on request.
Electrical & thermalNon-conductive spacers, barriers and isolators machined to size for electrical and thermal separation.
ToolingNon-marking guides, locators and wear strips that protect the product they handle.
In principle, all engineering plastics can be milled. The right choice depends on mechanical stress, temperature resistance, media contact, dimensional requirements and wear behaviour.
Precise, rotationally symmetrical components from engineering plastics — with tool geometry, cutting parameters and clamping tailored to each material.
CNC turning machines a rotating workpiece with specialised cutting tools to produce precise geometries and functional surfaces. Unlike metals, engineering plastics have lower thermal conductivity, higher thermal expansion and more elastic behaviour — so machining strategy, tool selection and heat management must be adapted to the material.
Positive tool geometries, polished cutting surfaces, generous chip clearance and low-vibration, stress-free clamping — plus controlled heat management to minimise thermally induced dimensional change.
Cylindrical and contour turning of outer surfaces.
Boring, reaming and precise internal fits.
Internal and external threads, burr-free and sharp-edged.
Sealing grooves, snap grooves, chamfers and facing.
On our CNC turn-mill centres, cross holes, milled surfaces, fits, contours and grooves are machined directly on the turned blank — improving accuracy, positional relationships of functional surfaces and process stability. Bar feeders and loading robots enable cost-effective series production of long, slender parts.

Few processors bring fibre reinforced plastics, laminated densified wood and laminated pressboard together under one roof. That breadth lets us match the material to the application rather than to our machinery.

Laminated densified wood is manufactured to IEC 61061 from veneers of common beech (Fagus sylvatica), bonded using curable synthetic resins under pressure and heat. The result combines high compressive and bending strength with excellent dielectric behaviour in transformer oil — which is why it remains the reference material for clamping and support structures inside power transformers.

The right material is the key factor for the design and service life of your component. We machine 25+ polymers — and help you choose the right one.
Hard, stiff plastics such as PEEK, PPS and PEI form few burrs and machine with high precision. POM machines well and dimensionally accurately. Tougher, softer materials — PE, PA and especially PTFE — are prone to burr formation and warping and require a tailored process. Fibre-reinforced grades are abrasive and demand adapted tooling: the higher the reinforcement content, the more complex the machining.
