Case Study: Camshaft Kit Supply for a mining contractor in Central America
Camshaft Kit for A mining contractor in Central America
A mining contractor came to us with a camshaft kit programme for Central 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
- Lead time that slipped twice before bulk started
- Inconsistent hardness between lots
- Packing that arrived crushed at the port

What was specified
| Part | Camshaft Kit |
|---|---|
| Client | A mining contractor |
| Market | Central America |
| Volume | 20,000 pieces across 2 specifications |
| Base material | Polypropylene |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | E-mark |
How it was resolved
- The specification was rebuilt around Polypropylene 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 4-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- 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.
