Case Study: Gearbox Solenoid Supply for a workshop chain in the Middle East

Gearbox Solenoid for A workshop chain in the Middle East

A workshop chain came to us with a gearbox solenoid programme for the Middle East. 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

  • Lead time that slipped twice before bulk started
  • A supplier who changed material without saying so
  • Packing that arrived crushed at the port

ClientA workshop chain
Marketthe Middle East
Volume10,000 pieces across 2 specifications
Base materialChromed Steel
Sampling rounds3
Delivery window6 weeks from PO to ex-factory
ComplianceISO/TS 16949

How it was resolved

  1. The specification was rebuilt around Chromed Steel 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 6-week window.
  • Unit cost held within 1.5% 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.

Send the specification you are working to and we will confirm what we can match, what we would change and why.
