Custom Zipper — Pewter with Die-Casting
We supply zipper to garment factories and brands, built in Pewter with die-casting for outerwear and jacket programmes. On a trim like this the specification that decides the outcome is pull strength of the slider and the stop, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 2000 pieces per style per finish.
The failures here are predictable: inconsistent sizing between production runs, or minimum order quantities far above what a growing brand can absorb. We lock material, finish, dimension and tolerance before bulk, and prepare GB 18401 safety classification with GB/T 29862 fibre labelling so the shipment clears instead of sitting at port while your selling season passes.

- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment

- 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 GRS recycled content claim are prepared for the destination market. We ship to Shanghai or Shenzhen 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 pull strength of the slider and the stop.
FAQ
Which compliance documents do you provide?
We prepare GRS recycled content claim and the supporting test reports for the destination market.
How do you control colour on reorders?
The approved reference and the bulk standard are retained, and every reorder is checked against them before shipment.
How long does sampling take?
A first sample takes 7 working days, and each revision about 4 days.
Can you match a reference sample?
Yes. Send the trim and we match material, finish and shade, then confirm on a pre-production sample before bulk.
