Production Process

The bonded process runs in eight stages.

Watch the seamless bonded bra production process

1

Glue Brushing

Brush glue onto the first layer of fabric.

Machines: SZS-001 · SZS-12070 (all-in-one)

2

Precise Bonding

Align the two fabric layers precisely and bond them together on a board flipping machine. With the SZS-12070 all-in-one machine, one machine completes both glue brushing and bonding.

Machines: SZY-60110 · SZS-12070 (all-in-one)

3

Baking

Bake the bonded pieces at about 120°C for about 15 minutes.

Machines: SZK-001

4

Edge Cutting

After cooling, cut off the excess material with a precision hydraulic four-column cutting machine and a trimming die.

Machines: SZQ-40T

5

Cup Shape Setting

Heat press the trimmed pieces into cup shape on a fabric cup molding machine before the bra cups are placed.

Machines: SZD-850 · SZD-850A

6

Cup Film Lamination

Laminate the bra cups with film on a film suction machine.

Machines: SZX-819

7

Cup Fixing

Place the laminated cup inside the shaped bra. Hot and cold press it so the cup stays fixed in the bra.

Machines: SZD-813D

8

Bar Tacking & Back Closure

Bar tack the bra with a sewing machine and attach the back closure with a back hook machine. The bra is then finished.
