Custom Eyelet — Brass with Ultrasonic Welding
We supply eyelet to garment factories and brands, built in Brass with ultrasonic welding for uniform and corporate programmes. On a trim like this the specification that decides the outcome is setting tooling tolerance, which decides whether the line runs clean, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 1000 pieces per style per finish.
The failures here are predictable: unclear responsibility when a defect shows up after washing, or a supplier who disappears once the deposit is paid. 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
- Drawing or reference sample review, with size and finish confirmed
- Material selection and a finish sample or strike-off
- Prototype made to the agreed inner diameter
- Fit and wash test on the actual garment fabric, then a pre-production sample
- Bulk run with ultrasonic welding 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 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 setting tooling tolerance.
