Custom Button — Aluminium with Ultrasonic Welding
We supply button to garment factories and brands, built in Aluminium with ultrasonic welding for outerwear and jacket programmes. On a trim like this the specification that decides the outcome is hole burr, because a rough burr cuts thread on the line, 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: a finish that tarnishes or rubs off after washing, or inconsistent sizing between production runs. 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.

- Denim and workwear — hard-wearing finishes that survive industrial washing
- Outerwear and tailoring — matched to the shell fabric so it drapes with the garment

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 hole burr.
FAQ
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.
Can you do small runs across many designs?
Yes — many studio and boutique programmes run small quantities across a wide design set.
What packing options are available?
Bulk packed, carded, or packed to your own size and design ratio with barcodes applied.
