O-Ring for an Airline Catering Supplier in India
An Airline Catering Supplier approached us with a o-ring requirement for the India 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
- A zipper puller that broke under pull test at the warehouse
- Reorders that quietly changed supplier and changed the hand feel
What we specified
| Item | O-Ring |
|---|---|
| Client type | An Airline Catering Supplier |
| Market | India |
| Order volume | 2,000 pieces across 2 specifications |
| Base material | Silicone |
| Standard size | 38 mm Width |
| Finish | Pearlescent Coating |
| Sampling rounds | 2 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around Silicone and locked the tolerance before bulk.
- The finish was moved to Rose Gold Plating 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
- 2,000 pieces delivered inside the 10-week window.
- Unit cost held within 1.5% of the original quotation.
- Inspection-related rejection stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Approve a pre-production sample made from the actual bulk base material. Substitute material behaves differently in finishing.
