Custom Zipper — Aluminium with Soft Enamel Fill
We supply zipper to garment factories and brands, built in Aluminium with soft enamel fill for denim and workwear programmes. On a trim like this the specification that decides the outcome is tape shrinkage matched to the garment fabric, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 5000 pieces per style per finish.
The failures here are predictable: inconsistent sizing between production runs, or a supplier who disappears once the deposit is paid. We lock material, finish, dimension and tolerance before bulk, and prepare CPSIA and California Prop 65 compliance so the shipment clears instead of sitting at port while your selling season passes.

How we produce it
- Drawing or reference sample review, with size and finish confirmed
- Material selection and a finish sample or strike-off

- Bulk run with soft enamel fill applied under controlled settings
- In-line inspection, final AQL 2.5 inspection and packing to your ratio
Where it is used
- Denim and workwear — hard-wearing finishes that survive industrial washing
- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment
- Childrenswear and schoolwear — tested to the destination's safety standard
- Bridal and eveningwear — small runs with hand-finished detail
- Uniform and corporate programmes — repeatable spec held on file for reorders

Packing, testing and delivery
Trims are packed to the ratio you specify — by size, by colour or by garment set — with barcodes applied where the line needs them. Test reports for EN 71 part 3 for decorative components are prepared for the destination market. We ship to Los Angeles or New York with the commercial invoice, packing list and certificate of origin, and hold the approved reference so reorders reproduce the same material, the same finish and the same tape shrinkage matched to the garment fabric.
