Material Certificates and Quality Documentation
When your customer audits your supply chain, the question is never whether the part measures correctly — it is whether you can prove where the material came from. Certificates are that proof, and we treat them as part of the product.
Why equipment manufacturers choose us
EN 10204 3.1 as standard
Material certificates available with your parts, tied to the batch and the drawing revision.
Backed by measurement
Certificate chemistry is cross-checked on our spectrometer, so the paper matches the metal.
Audit-ready package
Certificates, dimensional reports and traceability records form one consistent documentation set.
Material Certificates
Real capability windows — verified in-house, not estimated.

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.
