O-Ring for a Footwear Factory in Argentina
A Footwear Factory approached us with a o-ring requirement for the Argentina 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
- Lead time quoted without the plating or dyeing sub-process
- Reorders that quietly changed supplier and changed the hand feel
- A spec that lived in an email instead of a tech pack
What we specified
| Item | O-Ring |
|---|---|
| Client type | A Footwear Factory |
| Market | Argentina |
| Order volume | 50,000 pieces across 4 specifications |
| Base material | Bamboo |
| Standard size | 38 mm Width |
| Finish | Black Nickel Finish |
| Sampling rounds | 4 |
| Delivery window | 6 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Bamboo and locked the tolerance before bulk.
- The finish was moved to Antique Copper 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
- 50,000 pieces delivered inside the 6-week window.
- Unit cost held within 4.5% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- The specification is now 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.
