PEEK Machining for Demanding Equipment
PEEK is the engineering polymer you reach for when metals fail: chemical attack, high continuous temperatures, electrical insulation or weight. But plastic is not 'easier to machine' — it moves, creeps and melts differently than metal, and tooling must respect that.
Why equipment manufacturers choose us
Plastics machined like we mean it
Sharp tool geometry, controlled heat and clamping pressure tuned for polymers — not metal parameters applied to plastic.
Tolerances that survive the material
PEEK's thermal expansion is several times that of metals; we account for it in the measurement strategy and inspection conditions.
Cleanliness options for sensitive equipment
ESD-safe and cleanroom packaging for components destined for wafer equipment and analytical instruments.
PEEK Machining
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Material | PEEK (unfilled, glass- and carbon-filled grades) |
| Typical tolerance | ±0.01 mm standard; ±0.005 mm where the material allows |
| Temperature capability | Continuous service ~260 °C (grade-dependent) |
| Chemical resistance | Excellent across aggressive media |
| Processes | CNC milling, turning, Swiss-type |
| Packaging | ESD-safe / ISO Class 7 cleanroom |
| Certificates | ISO 9001:2015 · IATF 16949:2016 · EN 10204 3.1 |
| Prototype lead time | Typically 5–10 working days |
Materials we machine
From Drawing to Delivered Part
A transparent, engineering-led process built for long-term supply programs — not one-off transactions.
Submit & Review
Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.
Quote & Material Plan
You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.
Machine & Inspect
In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.
Deliver & Support
Kitted, ESD-safe or ISO Class 7 cleanroom packaging, with local engineering and after-sales support through our German partner.
