Power Window Motor for A rental company in West Africa
A rental company came to us with a power window motor 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
- A fitment that looked right on paper and failed on the bench
- Warranty claims traced back to a single lot
- Documentation that arrived after the container shipped
What was specified
| Part | Power Window Motor |
|---|---|
| Client | A rental company |
| Market | West Africa |
| Volume | 20,000 pieces across 3 specifications |
| Base material | Forged Aluminium |
| Sampling rounds | 3 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | CCC |
How it was resolved
- The specification was rebuilt around Forged Aluminium 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 10-week window.
- Unit cost held within 3.0% 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
Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.
