Case Study: Clutch Slave Cylinder Supply for an online marketplace seller in Europe

Clutch Slave Cylinder for An online marketplace seller in Europe

An online marketplace seller 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
  • A fitment that looked right on paper and failed on the bench
  • Lead time that slipped twice before bulk started

MarketEurope
Volume10,000 pieces across 6 specifications
Base materialCeramic Composite
Sampling rounds2
Delivery window8 weeks from PO to ex-factory
ComplianceISO 9001

How it was resolved

  1. The specification was rebuilt around Ceramic Composite and the tolerance locked before bulk.
  2. A pre-production sample was approved and kept as the golden reference.
  3. Production ran with in-line inspection and a mid-run photo report.
  4. Cartons were packed to the client's own barcode and ratio specification.
  5. Documentation shipped with the goods instead of after them.

Result

  • 10,000 pieces delivered inside the 8-week window.
  • Unit cost held within 4.5% 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.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
