Custom Thread Trimmer — TPU with Die-Casting
We supply thread trimmer to garment factories and brands, built in TPU with die-casting for uniform and corporate programmes. On a trim like this the specification that decides the outcome is spring tension, which decides fatigue over a long run, so that is agreed in writing before bulk — not discovered when the first carton is opened on the line. Programmes start at 3000 pieces per style per finish.
The failures here are predictable: colour drift between the approved sample and the bulk trim, or packing that arrives mixed and unusable on the line. 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.

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 spring tension.
