Case Study: Glow Plug Supply for an agricultural cooperative in Europe

Glow Plug for An agricultural cooperative in Europe

An agricultural cooperative came to us with a glow plug 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

  • A specification nobody had written down
  • Premature wear on the first batch
  • Warranty claims traced back to a single lot

How it was resolved

  1. The specification was rebuilt around Silicone 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 1.0%.
  • The specification is on file, so reorders reproduce the approved sample.

What we would repeat

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.

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