AC Evaporator for A spare parts retailer in South Asia
A spare parts retailer came to us with a ac evaporator programme for South 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
- A supplier who changed material without saying so
- A fitment that looked right on paper and failed on the bench
- A specification nobody had written down
What was specified
| Part | AC Evaporator |
|---|---|
| Client | A spare parts retailer |
| Market | South Asia |
| Volume | 5,000 pieces across 3 specifications |
| Base material | Titanium Alloy |
| Sampling rounds | 3 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | SGS |
How it was resolved
- The specification was rebuilt around Titanium Alloy and the tolerance locked before bulk.
- A pre-production sample was approved and kept as the golden reference.
- Production ran with in-line inspection and a mid-run photo report.
- Cartons were packed to the client's own barcode and ratio specification.
- Documentation shipped with the goods instead of after them.
Result
- 5,000 pieces delivered inside the 5-week window.
- Unit cost held within 2.0% 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.

Send the part number, the annual volume and the target market, and we will come back with a specification and a sampling plan.
