Custom Interlining — PU Leather with Ultrasonic Welding
We supply interlining to garment factories and brands, built in PU Leather with ultrasonic welding for e-commerce and small-batch brands. On a trim like this the specification that decides the outcome is fusing window — temperature, pressure and time that actually bond, 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: inconsistent sizing between production runs, or packing that arrives mixed and unusable on the line. We lock material, finish, dimension and tolerance before bulk, and prepare SNI or SIRIM documentation per destination 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 weight
- 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 salt spray test for metal finishes are prepared for the destination market. We ship to Jakarta or Port Klang 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 fusing window — temperature.
