Silicone Patch for a Denim Manufacturer in Japan
A Denim Manufacturer approached us with a silicone patch requirement for the Japan 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 trim that passed sampling but failed in-line because it was never cycle tested
- Lead time quoted without the plating or dyeing sub-process
- Reorders that quietly changed supplier and changed the hand feel
What we specified
| Item | Silicone Patch |
|---|---|
| Client type | A Denim Manufacturer |
| Market | Japan |
| Order volume | 50,000 pieces across 4 specifications |
| Base material | TPU |
| Standard size | 5# Gauge |
| Finish | Silicone Wash Finish |
| Sampling rounds | 2 |
| Delivery window | 5 weeks from PO to ex-factory |
| Compliance | AATCC Test Methods |
How it was resolved
- We rebuilt the specification around TPU and locked the tolerance before bulk.
- The finish was moved to Pearlescent 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
- 50,000 pieces delivered inside the 5-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 1.5%.
- The specification is now on file, so reorders reproduce the approved sample.
What we would repeat
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
