O-Ring for a Hat and Cap Producer in Singapore
A Hat and Cap Producer approached us with a o-ring requirement for the Singapore market. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive freight and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Elastic that lost recovery after three washes
- A zipper puller that broke under pull test at the warehouse
- MOQ that was quoted per colourway rather than per style
What we specified
| Item | O-Ring |
|---|---|
| Client type | A Hat and Cap Producer |
| Market | Singapore |
| Order volume | 10,000 pieces across 3 specifications |
| Base material | Stainless Steel |
| Standard size | 50 mm Width |
| Finish | UV Printing |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | ISO 105 Colour Fastness |
How it was resolved
- We rebuilt the specification around Stainless Steel and locked the tolerance before bulk.
- The finish was moved to Rainbow Iridescent Finish after strike-off tests showed better durability.
- A pre-production sample was approved and retained 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.
Result
- 10,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.0%.
- The specification is now 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.
