Shock Cord for a Medical Textile Buyer in China
A Medical Textile Buyer approached us with a shock cord requirement for the China 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
- A spec that lived in an email instead of a tech pack
- Lead time quoted without the plating or dyeing sub-process
- Shade drift between the approved lab dip and the bulk lot
What we specified
| Item | Shock Cord |
|---|---|
| Client type | A Medical Textile Buyer |
| Market | China |
| Order volume | 10,000 pieces across 6 specifications |
| Base material | Aluminium |
| Standard size | 8# Gauge |
| Finish | Laser Engraved Finish |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | RoHS |
How it was resolved
- We rebuilt the specification around Aluminium and locked the tolerance before bulk.
- The finish was moved to Matte Black Coating 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 4-week window.
- Unit cost held within 2.0% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
