Non wovens ultrasonic welding solution with Sonic Italia:
Materials may be 100% synthetic or blend with up to 40% natural fibers. Acrylics, acetates, polyester, nylon, polypropylene, spandex and PVC are all suitable for bonding or cutting. In general, the higher the synthetic content, the easier it is to cut and seal with ultrasonic energy. Nonwowens ultrasonic welding including felted filter media are especially suited for ultrasonic bonding. Please visit our dedicated webpage


Advantages of non wovens ultrasonic welding


The rotary method works like a sewing machine and produces a continuous seam or pattern. This particular ultrasonic welding machine for nonwoven uses the principle of friction between the fabrics: using a pattern roller and an ultrasonic horn, the friction is greatly reduced if both sides rotate, instead of having a rolling pattern on a stationary horn.


  • Consistent material characteristics; ultrasonic bonding and cutting with ultrasonics eliminates thermal distortion of the nonwoven material and maintains softness, loft and air permeability of the material
  • Ultrasonic laminating allows for the ultrasonic bonding of materials with different melting points
  • Ultrasonic bonding produces environmentally friendly laminates. The laminates do not contain any adhesives or other consumables making them recyclable
  • Consistent weld quality even when laminating multiple layers of different materials or when bonding intermittently in cross machine direction
  • The nonwovens ultrasonic welding technology offers immediate system availability without heat-up time, fast set-up and reduced energy consumption
  • Major cost savings as a result of minimized scrap after machine start up and shut down
  • High production speeds with nonwoven ultrasonic bonding
