Case Study: Gearbox Solenoid Supply for a delivery platform in North Africa

Gearbox Solenoid for A delivery platform in North Africa

A delivery platform came to us with a gearbox solenoid programme for North 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 specification nobody had written down
  • Packing that arrived crushed at the port
  • Reorders that did not match the approved sample

MarketNorth Africa
Volume10,000 pieces across 6 specifications
Base materialNatural Rubber
Sampling rounds3
Delivery window4 weeks from PO to ex-factory
ComplianceSAE J431

How it was resolved

  1. The specification was rebuilt around Natural Rubber 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 4-week window.
  • Unit cost held within 2.0% 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

Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.

Share a sample or a drawing and we will quote against a written specification, not against a photograph.
