Case Study: Exhaust Manifold Supply for a wholesale group in the Middle East

Exhaust Manifold for A wholesale group in the Middle East

A wholesale group came to us with a exhaust manifold 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

  • Documentation that arrived after the container shipped
  • Reorders that did not match the approved sample
  • A specification nobody had written down

How it was resolved

  1. The specification was rebuilt around Sintered Metal 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 4-week window.
  • Unit cost held within 4.5% of the original quotation.
  • Inspection-related rejection stayed under 0.5%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
