Case Study: Cabin Filter Housing Supply for a mining contractor in Southeast Asia

Cabin Filter Housing for A mining contractor in Southeast Asia

A mining contractor came to us with a cabin filter housing programme for Southeast Asia. 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

• Packing that arrived crushed at the port
• Premature wear on the first batch
• Documentation that arrived after the container shipped

What was specified

How it was resolved

1. The specification was rebuilt around Brass 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

• 20,000 pieces delivered inside the 10-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

Approve a pre-production sample made from the actual bulk material. Substitute material behaves differently in service.
