Lock Technology

Quality control

Three gates before anything ships

Certified to ISO 9001, IATF 16949, ISO 14001 and ISO 45001, and controlled from incoming material to the packed carton — with the reports to prove it.

Inspection equipment at Lock Technology

Control points

Incoming, in process, outgoing

  • Incoming material

    Wire, bar and sheet are checked against the certificate of conformity, and the alloy is verified on the spectrometer before it is released to a machine.

  • In process

    First-off approval at every setup, then dimensional checks at a fixed frequency. Critical dimensions are charted, not sampled by eye.

  • Outgoing

    Final inspection on the finished part — dimensions, thread, plating thickness, appearance — then counted, packed and sealed.

Documentation

What ships with the parts

  • FAI report

    First article inspection against the drawing: every dimension, criticals called out, with the deviations discussed before mass production.

  • Full-size inspection report

    Batch-level dimensional record, traceable to the production lot.

  • Material and finish certificates

    Mill certificates, plating thickness and salt-spray results, RoHS declarations.

    On request for automotive programmes, with the control plan and process flow.
