Custom Zipper — Brass with Yarn Dyeing
We supply zipper to garment factories and brands, built in Brass with yarn dyeing for childrenswear and schoolwear. On a trim like this the specification that decides the outcome is slider smoothness across the full length, tested by hand on bulk, 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: unclear responsibility when a defect shows up after washing, or shade variation within one carton. 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.

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 REACH nickel-release test for metal findings 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 slider smoothness across the full length.
