Case Study: Radiator Cap Supply for a dealership group in South Asia

Radiator Cap for A dealership group in South Asia

A dealership group came to us with a radiator cap programme for South Asia. 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
  • Reorders that did not match the approved sample
  • Warranty claims traced back to a single lot

ClientA dealership group
MarketSouth Asia
Volume2,000 pieces across 3 specifications
Base materialReinforced Nylon
Sampling rounds3
Delivery window6 weeks from PO to ex-factory
ComplianceSAE J431

How it was resolved

  1. The specification was rebuilt around Reinforced Nylon 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 Cap production run

Result

  • 2,000 pieces delivered inside the 6-week window.
  • Unit cost held within 1.5% of the original quotation.
  • Inspection-related rejection stayed under 1.0%.
  • 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.
