Custom Zipper in Stainless Steel with Ultrasonic Welding for Childrenswear and Schoolwear

Custom Zipper — Stainless Steel with Ultrasonic Welding

We supply zipper to garment factories and brands, built in Stainless Steel with ultrasonic welding for outerwear and jacket programmes. 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: packing that arrives mixed and unusable on the line, or colour drift between the approved sample and the bulk trim. We lock material, finish, dimension and tolerance before bulk, and prepare UKCA and REACH documentation so the shipment clears instead of sitting at port while your selling season passes.

How we produce it

1. Drawing or reference sample review, with size and finish confirmed
2. Material selection and a finish sample or strike-off
3. Prototype made to the agreed gauge
4. Fit and wash test on the actual garment fabric, then a pre-production sample
5. Bulk run with ultrasonic welding applied under controlled settings
6. 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 REACH nickel-release test for metal findings are prepared for the destination market. We ship to Felixstowe 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

What packing options are available?

Bulk packed, carded, or packed to your own size and design ratio with barcodes applied.

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.

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.

What is the minimum order?

Programmes start at 500 pieces per style per finish. Mixed sizes are fine within one style.
