Clutch Slave Cylinder for A wholesale group in Europe
A wholesale group came to us with a clutch slave cylinder programme for 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
- Documentation that arrived after the container shipped
- Warranty claims traced back to a single lot
- Inconsistent hardness between lots
What was specified
| Part | Clutch Slave Cylinder |
|---|---|
| Client | A wholesale group |
| Market | Europe |
| Volume | 5,000 pieces across 4 specifications |
| Base material | Sintered Metal |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | E-mark |
How it was resolved
- The specification was rebuilt around Sintered Metal 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 6-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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
