Piston for A mining contractor in Southeast Asia
A mining contractor came to us with a piston programme for Southeast 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
- Documentation that arrived after the container shipped
- A supplier who changed material without saying so
- Lead time that slipped twice before bulk started
What was specified
| Part | Piston |
|---|---|
| Client | A mining contractor |
| Market | Southeast Asia |
| Volume | 10,000 pieces across 6 specifications |
| Base material | High Density Foam |
| Sampling rounds | 3 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | SGS |
How it was resolved
- The specification was rebuilt around High Density Foam 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
- 10,000 pieces delivered inside the 4-week window.
- Unit cost held within 1.5% 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
Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
