Case Study: Radiator Supply for a fleet operator in the Caribbean

Radiator for A fleet operator in the Caribbean

A fleet operator came to us with a radiator programme for the Caribbean. 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

  • Packing that arrived crushed at the port
  • A specification nobody had written down
  • Warranty claims traced back to a single lot

ClientA fleet operator
Marketthe Caribbean
Volume20,000 pieces across 6 specifications
Base materialAnodised Aluminium
Sampling rounds4
Delivery window10 weeks from PO to ex-factory
ComplianceSAE J431

How it was resolved

  1. The specification was rebuilt around Anodised Aluminium 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.

Radiator production run

Result

  • 20,000 pieces delivered inside the 10-week window.
  • Unit cost held within 3.0% 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

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