Ignition Coil for A wholesale group in West Africa
A wholesale group came to us with a ignition coil programme for West Africa. 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
- Packing that arrived crushed at the port
- Reorders that did not match the approved sample
- Inconsistent hardness between lots
What was specified
| Part | Ignition Coil |
|---|---|
| Client | A wholesale group |
| Market | West Africa |
| Volume | 10,000 pieces across 3 specifications |
| Base material | Tempered Glass |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | RoHS |
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
- 10,000 pieces delivered inside the 5-week window.
- Unit cost held within 4.5% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
