Case Study: Custom Two-Way Separating Zipper for a Car Interior Supplier in Kenya

Two-Way Separating Zipper for a Car Interior Supplier in Kenya

A Car Interior Supplier approached us with a two-way separating zipper requirement for the Kenya 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

• Shrinkage that only showed up after the first wash
• MOQ that was quoted per colourway rather than per style
• Lead time quoted without the plating or dyeing sub-process

What we specified

How it was resolved

1. We rebuilt the specification around Ceramic and locked the tolerance before bulk.
2. The finish was moved to Mercerised Finish after strike-off tests showed better durability.
3. A pre-production sample was approved and retained as the golden reference.
4. Production ran with in-line inspection and a mid-run photo report.
5. 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 3.0% 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

Fix the specification count early. Adding variants after production starts is the most expensive change a client can request.
