Case Study: Serpentine Belt Supply for a mining contractor in the Middle East

Serpentine Belt for A mining contractor in the Middle East

A mining contractor came to us with a serpentine belt programme for the Middle East. The brief was ordinary and unforgiving at the same time: a fixed launch window, a landed cost that had to survive freight and duty, and a part that had to match an existing sample. This case records what was specified, what went wrong in sampling and how the bulk order landed.

The starting point

  • A supplier who changed material without saying so
  • Reorders that did not match the approved sample
  • Lead time that slipped twice before bulk started

Volume2,000 pieces across 4 specifications
Base materialSemi-Metallic Compound

Delivery window5 weeks from PO to ex-factory
ComplianceSGS

How it was resolved

  1. The specification was rebuilt around Semi-Metallic Compound and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 2,000 pieces delivered inside the 5-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 1.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
