Case Study: Dual Mass Flywheel Supply for a rental company in West Africa

Dual Mass Flywheel for A rental company in West Africa

A rental company came to us with a dual mass flywheel programme for West Africa. 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

  • Lead time that slipped twice before bulk started
  • A fitment that looked right on paper and failed on the bench
  • Packing that arrived crushed at the port

How it was resolved

  1. The specification was rebuilt around Neoprene 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

  • 50,000 pieces delivered inside the 10-week window.
  • Unit cost held within 4.5% 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.
