Quality Assurance & Inspection

Inspection is a process, not a final gate. Every critical dimension is measured, documented and traceable to the batch — under an ISO 9001:2015 quality system.

ISO 9001:2015 / GB/T 19001-2016, certified by GICG (UKAS and IAF MLA accredited), certificate U24Q2GZ688444R4S valid until 17 October 2027; and IATF 16949:2016 for automotive work, certified by AENOR, certificate RA02-0022/2022, IATF number 0444369, valid until 22 March 2028, scope LIDAR metal shells and metal spectacle frames with product design excluded.
No. ProtoTech does not hold AS9100 or ISO 13485 and does not claim them. If your programme requires AS9100, Nadcap-controlled special processes or ISO 13485, say so and ProtoTech will tell you plainly what it can and cannot support.
A Zeiss SPECTRUM coordinate measuring machine for geometry and position, a TRIMOS V5 digital height gauge for heights and steps, an AI-Vision AIM432P vision measuring system for fine features, and SPECTROMAXx with NCS SparkCCD 6000A spark-OES spectrometers for material chemistry. All of it is in house.
A full dimensional layout of the critical features on the Zeiss CMM, material chemistry confirmed by spectrometer against the EN/DIN number, and EN 10204 3.1 certificates for the batch - reported against the drawing revision you released.
To batch level. The material batch, the inspection results for that batch and the drawing revision it was built to are recorded, so a later batch can be compared against an earlier one.

Tell us about your program. The fields below help our engineering team prioritize recurring, long-term supply programs with equipment manufacturers.

What happens after you send your files

  • Within 1 business day an engineer — not a salesperson — reviews your drawings and replies.
  • DFM review: tolerances, material and risk flags, before any cutting begins.
  • Your quote includes a material-verification plan: grade, EN/DIN check, certificate strategy.

Critical features are verified in house · material chemistry confirmed by spectrometer · EN 10204 3.1 certificates available.

Recurring programs and orders of 1,000+ pcs are prioritised by our engineering team.
The number of parts per order — it lets us price tooling and batch setup correctly instead of guessing at a range.
Several different parts? Email your list and drawings to ellie@prototech-machining.com and we will quote them together.
e.g. 120 pcs · 6061-T6 aluminium · black anodise · mates with bracket PT-1042
Built for qualified programs.
Our form captures production type, annual quantity and project status up front — so we can focus engineering resources on long-term supply relationships, not one-off inquiries.
