Timing Chain for A mining contractor in Eastern Europe
A mining contractor came to us with a timing chain programme for Eastern Europe. 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
- Warranty claims traced back to a single lot
- Lead time that slipped twice before bulk started
- A supplier who changed material without saying so
What was specified
| Part | Timing Chain |
|---|---|
| Client | A mining contractor |
| Market | Eastern Europe |
| Volume | 5,000 pieces across 3 specifications |
| Base material | Neoprene |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | DOT |
How it was resolved
- The specification was rebuilt around Neoprene 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 10-week window.
- Unit cost held within 2.0% 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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
