Case Study: Custom Jacket Zipper Slider for a Private Clinic in the United States
Jacket Zipper Slider for a Private Clinic in the United States
A Private Clinic approached us with a jacket zipper slider requirement for the United States. The brief was specific: a defined look, a hard launch date and a unit cost that had to survive shipping and duty. This case study records what was specified, what went wrong in sampling and how the bulk order was delivered.
The challenge
- Inconsistent sizing between production runs
- Long lead times that miss the selling season
- Minimum order quantities far above what a growing brand can absorb

What we specified
| Product | Jacket Zipper Slider |
|---|---|
| Client type | A Private Clinic |
| Market | the United States |
| Order volume | 5,000 pieces across 6 colourways |
| Base fabric | Down-Proof Nylon |
| Decoration | Ultrasonic Welding |
| Size range | 2-12Y |
| Sampling rounds | 3 |
| Delivery window | 6 weeks from PO to ex-factory |
How it was resolved
- We rebuilt the tech pack around Down-Proof Nylon and locked shrinkage allowance before grading.
- Decoration was moved to Ultrasonic Welding after strike-off tests showed better wash 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 size ratio specification.

Result
- 5,000 pieces delivered inside the 6-week window.
- Unit cost held within 4.5% of the original quotation.
- Return rate linked to fit or workmanship stayed under 2.0%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one process owner on both sides. Most delays come from hand-offs, not from machines.
