Case Study: Dual Mass Flywheel Supply for an e-commerce seller in Europe

Dual Mass Flywheel for An e-commerce seller in Europe

An e-commerce seller came to us with a dual mass flywheel programme for Europe. 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

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

ClientAn e-commerce seller
MarketEurope
Volume50,000 pieces across 4 specifications
Base materialCarbon Steel
Sampling rounds2
Delivery window5 weeks from PO to ex-factory
ComplianceIATF 16949

How it was resolved

  1. The specification was rebuilt around Carbon Steel 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 5-week window.
  • Unit cost held within 4.5% of the original quotation.
  • Inspection-related rejection stayed under 2.0%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
