Zipper Chain for a Theatre Costume Workshop in Belgium
A Theatre Costume Workshop approached us with a zipper chain requirement for the Belgium 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
- Elastic that lost recovery after three washes
What we specified
| Item | Zipper Chain |
|---|---|
| Client type | A Theatre Costume Workshop |
| Market | Belgium |
| Order volume | 5,000 pieces across 2 specifications |
| Base material | Zinc Alloy |
| Standard size | 20 mm Width |
| Finish | Silicone Wash Finish |
| Sampling rounds | 2 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | BSCI |
How it was resolved
- We rebuilt the specification around Zinc Alloy and locked the tolerance before bulk.
- The finish was moved to Anodised 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
- 5,000 pieces delivered inside the 4-week window.
- Unit cost held within 2.0% 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
Lock the material standard before sampling. Once the base changes, every downstream approval has to be redone and the calendar slips.
