Custom Zipper — Aluminium with Screen Printing
We supply zipper to garment factories and brands, built in Aluminium with screen printing 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 500 pieces per style per finish.
The failures here are predictable: minimum order quantities far above what a growing brand can absorb, or a supplier who disappears once the deposit is paid. 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.

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 screen printing 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 salt spray test for metal finishes 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.
FAQ
Can you do small runs across many designs?
Yes — many studio and boutique programmes run small quantities across a wide design set.
How long does sampling take?
A first sample takes 14 working days, and each revision about 4 days.
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.
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.
