Batch Traceability and Drawing Revision Control
Traceability answers two questions that matter years later: which material went into this batch, and which revision was it built to. We keep both — so repeat orders match the original and audits have something to read.
Why equipment manufacturers choose us
Repeat orders that match
Batch records and controlled revisions mean reordering part 500 looks like part 1, not a re-interpretation.
Audit-ready records
Material batch, inspection results and revision history form a consistent set your customer's auditor can follow.
Change control
Drawing revisions are recorded and applied deliberately — no silent substitutions between batches.
Traceability
Real capability windows — verified in-house, not estimated.
| Capability | Specification |
|---|---|
| Traceability level | Batch level, tied to part number and revision |
| Records kept | Material batch · inspection reports · revision history |
| Drawing control | Revision recorded and applied per order |
| Complementary evidence | EN 10204 3.1 certificates · spectrometer verification |
| Packaging | Kitted, ESD-safe or ISO Class 7 cleanroom options with identification |
| Quality system | ISO 9001:2015 (GICG) |
| Availability | Prototypes through recurring series programs |
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.
