Quality & metrology

Measured, recorded, and shipped with the parts.

Your incoming inspection should find nothing. That is the standard our quality team of 46 works to, and the numbers below are how we hold ourselves to it.

38PPM, customer-reported defects, rolling 12 months
≥ 1.67Cpk on every critical characteristic, monitored by SPC
97.4%On-time-in-full, last four quarters
0Major non-conformities at the last two surveillance audits

Metrology lab

A 1,800 sq ft lab held at 20 ±1 °C.

Parts soak for two hours before measurement. Every gauge is calibrated against references traceable to national standards through NABL-accredited labs.

Certifications

Audited by third parties, every year.

Certificates are issued by accredited registrars and available on request. Customer audits are welcome with two weeks’ notice; we have hosted 31 in the last three years.

From incoming material to dispatch

Eight gates. A part cannot skip one.

Each gate has an owner, a record and a hold point. The traveller card follows the batch, and the ERP will not print a dispatch label until all eight are signed.

  1. 1

    Contract reviewEngineering · before the PO

    Drawing, specs and special characteristics reviewed for manufacturability. APQP plan, PFMEA and control plan agreed with you.

    • DFM report
    • PFMEA
    • Control plan
  2. 2

    Incoming materialStores · on receipt

    Mill certificates to EN 10204 3.1 checked against the PO. Every heat verified on the spectrometer before it is booked into stock.

    • 3.1 cert
    • PMI check
    • Hardness
  3. 3

    TraceabilityStores · at cutting

    Billets saw-cut and etched with the heat number. The number travels with the batch through every operation to the final label.

    • Heat number
    • Traveller card
  4. 4

    First-off approvalQuality · each setup

    The first part off every setup is measured in full on the CMM. Production does not start until quality signs the first-off.

    • Full CMM layout
    • Setup sign-off
  5. 5

    In-process controlOperator · every shift

    On-machine probing on critical features, SPC charts at the machine, tool life managed by count. Out-of-control points stop the machine.

    • On-machine probing
    • SPC
    • Cpk ≥ 1.67
  6. 6

    Final inspectionQuality lab · each batch

    Critical features measured on the CMM to the sampling plan in your PPAP or FAI. Visual check under 1,000 lux for burrs and handling marks.

    • CMM report
    • PPAP Level 3
    • AS9102 FAI
  7. 7

    Cleaning & preservationFinishing · before packing

    Ultrasonic washing to your cleanliness spec, dried and wrapped in VCI film the same day. Particle-count reports where the drawing asks.

    • Ultrasonic wash
    • VCI
    • ISO 16232 on request
  8. 8

    Packing & dispatchLogistics · Plant 2, Arasur

    Packed in ISPM-15 crates or returnable totes, labelled with part, heat and lot numbers. CMM report, material cert and CoC travel in the crate and by email.

    • ISPM-15 crates
    • Certificate of conformance
    • Packing list

When something goes wrong

An 8D report within 10 working days.

Containment starts within 24 hours: we sort stock at our plant and, for European and US customers, through a third-party sorting partner near your site. Root cause, corrective action and a revised PFMEA follow in the 8D.
