Components can be either 100% synthetic or blended with up to 40% natural fibers. Whether it is acrylics, acetates, polyester, nylon, polypropylene, spandex or PVC, they are all suitable for bonding or incising with ultrasounds.

Usually, the more nonwovens an item has, the easier it is to process it with ultrasonics, allowing to cut and weld fabrics up to a 200 GSM thickness.

Sonic Italia develops and manufactures ultrasonic nonwovens welding tools, widely used in the technical, filtration, apparel and medical gear fields. 

Nonwovens soldering may be continuous, with rotatory modules or step by step systems integrated into pneumatic actuators.

Advantages of ultrasonic nonwovens welding

The rotary method for nonwovens works just like a sewing machine to produce a uniform seam. This particular machinery for nonwovens uses a principle of friction between fabrics: by employing a patterned roller and a rotating sonotrode, it is possible guarantee an unparalleled stability and reliability.

Some of the most evident benefits of ultrasonic nonwovens welding are:

  • It forgoes thermal distortion of nonwoven fabrics while keeping their softness and permeability;
  • Ultrasonic lamination allows for materials with different melting points to fuse together;
  • It produces environmentally friendly laminates. They don't need any adhesives or consumables, thus making them entirely recyclable;
  • Constant quality even when it comes to several layers of different materials or when intermittent welding is done in a transversal direction;
  • The nonwovens seaming technology offers systems that are available immediately, that needs no heating time, is fast to setup and consumes little energy;
  • Substantial cost savings due to minimum equipment starting and shut down times;
  • Higher production speeds.
