Case Study: Power Steering Hose Supply for a mining contractor in Central America

Power Steering Hose for A mining contractor in Central America

A mining contractor came to us with a power steering hose programme for Central America. 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

  • Warranty claims traced back to a single lot
  • A supplier who changed material without saying so
  • A fitment that looked right on paper and failed on the bench

Volume2,000 pieces across 4 specifications
Base materialEPDM Rubber
Sampling rounds2
Delivery window4 weeks from PO to ex-factory
ComplianceCCC

How it was resolved

  1. The specification was rebuilt around EPDM 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.

Power Steering Hose production run

Result

  • 2,000 pieces delivered inside the 4-week window.
  • Unit cost held within 3.0% of the original quotation.
  • Inspection-related rejection stayed under 1.0%.
  • 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.

Planning something similar?

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