Ignition Coil for A mining contractor in Eastern Europe
A mining contractor came to us with a ignition coil 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
- Reorders that did not match the approved sample
- Inconsistent hardness between lots

What was specified
| Part | Ignition Coil |
|---|---|
| Client | A mining contractor |
| Market | Eastern Europe |
| Volume | 5,000 pieces across 2 specifications |
| Base material | Reinforced Nylon |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | REACH |
How it was resolved
- The specification was rebuilt around Reinforced Nylon 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 5-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- 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.
