First Article Inspection Before Series Release

Series production should never start on an unverified part. Before we schedule recurring batches, the first article is fully inspected and documented — giving you an approved reference and us a confirmed process.

Why ProtoTech

Why equipment manufacturers choose us

Verified before volume

Every critical dimension on the first article is measured and reported before any series is scheduled.

An approval reference for you

The first-article report becomes the shared reference between your quality team and ours.

Process confirmation for us

FAI proves the setup, tooling and parameters produce the drawing — before we repeat them 500 times.

How we work

From Drawing to Delivered Part

A transparent, engineering-led process built for long-term supply programs — not one-off transactions.

1

Submit & Review

Send drawings and program context. Our engineers run a DFM review and flag tolerances, materials and risk before any cutting begins.

2

Quote & Material Plan

You receive a transparent quote plus a material-verification plan — grade, EN/DIN check and certificate strategy for your application.

3

Machine & Inspect

In-house precision machining, then Zeiss CMM dimensional inspection and spectrometer material verification on critical batches.

4

Deliver & Support

Kitted, ESD-safe or cleanroom packaging, with local engineering and after-sales support through our German partner.

FAQ

Frequently asked questions

A full dimensional layout of the drawing's critical features on our Zeiss CMM, documented in a report tied to your part number and revision — plus material evidence for the stock used.
No. Recurring production is scheduled after first-article approval, so the series is built from a verified reference.
Yes — prototypes are inspected with the same discipline; FAI becomes the gate specifically when a part moves into recurring production.
