Advantages of Ultrasonic
Ultrasonic bonding is a reliable, well-established, and environmentally
friendly process that utilizes ultrasonic vibrations to fuse synthetics
and nonwoven materials. This bonding method does away with the need for
needles, thread, adhesives, or other consumables, while also eliminating
related concerns about stitch holes, glue gaps, and broken threads.
Sonobond's ultrasonic bonding process is completed in
only seconds, takes up a minimal amount of material at the seam, and provides
a much stronger and dependable bond than is produced with stitching, glue,
or hot air methods. Sonobond bonders have the added advantage of being
four times faster than sewing machines and ten times faster than adhesive
machines. The equipment is also easy to operate and requires minimal training.
Sonobond's ultrasonic technology is so reliable that it is used to assemble
the disposable medical apparel that helps protect personnel from hazardous
