Cooling Fan for A taxi fleet in Latin America
A taxi fleet came to us with a cooling fan programme for Latin 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
- Inconsistent hardness between lots
- Premature wear on the first batch
- A specification nobody had written down
What was specified
| Part | Cooling Fan |
|---|---|
| Client | A taxi fleet |
| Market | Latin America |
| Volume | 5,000 pieces across 3 specifications |
| Base material | ABS Plastic |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | REACH |
How it was resolved
- The specification was rebuilt around ABS Plastic and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 5,000 pieces delivered inside the 6-week window.
- Unit cost held within 2.0% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
