Quality

Quality control process

Five checkpoints between your drawing and your dock, and the record you receive at each one. None of it is optional — this is how every order runs.

  1. 01 IQC

    Incoming inspection

    Material grade and dimensions checked against the purchase spec before anything reaches the floor. Certified critical components are verified against their own certificate numbers.

    → Material certificate on file

  2. 02 FAI

    First article

    Every critical dimension on the drawing is measured on the first parts off the tool, before the run continues. If a feature cannot be held, you hear about it at this point rather than at incoming inspection on your side.

    → FAI / dimensional report ships with the samples

  3. 03 IPQC

    In-process control

    Sampling at each process step — stamping, machining, surface treatment, assembly — so a drifting tool is caught in the batch it affects.

    → Process inspection records

  4. 04 FQC / OQC

    Final and outgoing

    Power units get a 100% electrical function test and hi-pot before packing. Metal parts are sampled to the agreed AQL, with appearance and critical dimensions rechecked after plating or anodising.

    → Outgoing inspection report per lot

  5. 05 CAR

    Corrective action

    An RMA starts with containment, then root cause using fishbone and 5-why, then a verified fix. You get the 8D report, not a note saying the operator was retrained.

    → 8D report with verification
