Rubber Patch for a Logistics Company in Portugal
A Logistics Company approached us with a rubber patch requirement for the Portugal 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
- Reorders that quietly changed supplier and changed the hand feel
- Cartons packed to the factory ratio instead of the buyer's size ratio

What we specified
| Item | Rubber Patch |
|---|---|
| Client type | A Logistics Company |
| Market | Portugal |
| Order volume | 20,000 pieces across 6 specifications |
| Base material | Glass |
| Standard size | 32 mm Width |
| Finish | Rainbow Iridescent Finish |
| Sampling rounds | 4 |
| Delivery window | 10 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around Glass and locked the tolerance before bulk.
- The finish was moved to Sandblasted 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
- 20,000 pieces delivered inside the 10-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
Keep one accountable owner on both sides. Most delays come from hand-offs, not from machines.
