Quality & Certification

For aftermarket buyers, a supplier's quality system is the first filter. The IATF 16949 certified production behind these components, and our in-house testing capability, are documented here for your review.

Certifications

Copies of all certificates are available on request, including for your supplier audit file.

In-House Testing

Capabilities we hold internally, so verification does not depend on third-party turnaround.

Test Equipment Standard / Method Frequency

Test scope varies by part. Confirm the applicable specification for your part number before ordering.

Quality Control Through Production

Control points are placed where defects are actually likely to occur, not only at final inspection.

  • Incoming material — resin lot certificates checked and recorded
  • Moulding setup — process parameters recorded and locked per part number
  • In-process — first-off approval, then periodic checks through the run
  • Final inspection — dimensional check and functional verification
  • Packing — carton labelling and traceability code applied
