Ultrasonic Line Bonding Machine

Bonded or sew free garment (as underwear, sportswear, medical and outerwear) now is popular on the world market like , and people are using many technique to bond with adhesive & fabric and giving lots of unique shape & design. Ultrasonic bonding is such an industrial technique where high-frequency ultrasonic acoustic vibrations are locally applied to work pieces being held together under pressure to create a solid-state weld without adhesive. In ultrasonic line bonding machine, there are no connective bolts, nails, soldering materials, or adhesives necessary to bind or cut and seal the fabric edge with smooth curve & design.

It is mentionable that this machine can give good result on bonding synthetics and non-woven features where the process is to cut and seal the fabric edge. It is also give expected result on bonding fabric as non-woven, chemical fibrous cloth, nylon cloth, knitting cloth, non spin cloth, gush glue cotton, PE paper, PE + cloth, and so on. For designed oriented bonded garments, the ultrasonic machine should have capability to work with stretch fabrics, coated and laminated, knits and fleece materials providing smooth uninterrupted seams. The seam is strengthened by applying a tape either to the outside or the underside of the seam.

Ultrasonic bonding machine must have some merits over conventional stitch methods as:

a) Provides a fully watertight seam by eliminating needle and thread
b) Seams are less bulky
c) Uses small seam allowances creating flatter seams
d) Improves comfort levels on next to skin garments
