An Overview
It is amazing to see what ultrasonic energy can achieve in joining, cutting, patterning, and quilting on synthetic fabrics. These operations are done without thread or adhesives at speeds much greater than sewing machines. As the fabric passes under the machine's horn, ultrasonic vibration causes materials to fuse. Vibration also cuts and seals edges to eliminate fraying.

Ultrasonic bonding uses high-frequency sound to generate localized heat through vibration. A rotary ultrasonic assembly can be mounted in any orientation, available in 35 kHz with bond widths up to 15mm. It produces soft, smooth seams impervious to moisture or fluids.

Within the hygiene industry, this technology is used for adult and baby diapers, surgical wraps, and medical face masks. It is ideal for bonding, attachment, embossing, and lamination of thermoplastic materials.
