Cam Buckle for a Supermarket Own-Brand Team in South Africa
A Supermarket Own-Brand Team approached us with a cam buckle requirement for the South Africa 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 zipper puller that broke under pull test at the warehouse
- Shade drift between the approved lab dip and the bulk lot
- Shrinkage that only showed up after the first wash
What we specified
| Item | Cam Buckle |
|---|---|
| Client type | A Supermarket Own-Brand Team |
| Market | South Africa |
| Order volume | 20,000 pieces across 4 specifications |
| Base material | ABS Resin |
| Standard size | 32 mm Width |
| Finish | Antique Brass Plating |
| Sampling rounds | 4 |
| Delivery window | 4 weeks from PO to ex-factory |
| Compliance | REACH SVHC Screening |
How it was resolved
- We rebuilt the specification around ABS Resin and locked the tolerance before bulk.
- The finish was moved to Chrome Plating 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 4-week window.
- Unit cost held within 3.0% of the original quotation.
- Inspection-related rejection stayed under 0.5%.
- 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.
