Case Study: Gasket Set Supply for a bus operator in North America

Gasket Set for A bus operator in North America

A bus operator came to us with a gasket set programme for North America. 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

  • Warranty claims traced back to a single lot
  • A supplier who changed material without saying so
  • Packing that arrived crushed at the port

How it was resolved

  1. The specification was rebuilt around Stainless 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.

Gasket Set production run

Result

  • 2,000 pieces delivered inside the 6-week window.
  • Unit cost held within 2.0% 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

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
