Transmission Cooler for A mining contractor in Latin America
A mining contractor came to us with a transmission cooler 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
- A fitment that looked right on paper and failed on the bench
- A specification nobody had written down
- Inconsistent hardness between lots
What was specified
| Part | Transmission Cooler |
|---|---|
| Client | A mining contractor |
| Market | Latin America |
| Volume | 20,000 pieces across 4 specifications |
| Base material | Tempered Glass |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | E-mark |
How it was resolved
- The specification was rebuilt around Tempered Glass 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
- 20,000 pieces delivered inside the 10-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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
Planning something similar?
Share a sample or a drawing and we will quote against a written specification, not against a photograph.
