Ultrasonics offer cost benefit over adhesives.Ultrasonic welding Ultrasonic welding is an industrial whereby high-frequency ultrasonic acoustic vibrations are used to weld objects together, usually plastics, and especially for joining dissimilar materials. is being considered as a cost-effective replacement for adhesives to bond nonwovens, films, and textiles. With the recent spike in energy prices causing adhesive prices to more than double, manufacturers are searching for new alternatives, according to according to prep. 1. As stated or indicated by; on the authority of: according to historians. 2. In keeping with: according to instructions. 3. Herrmann Ultrasonics ultrasonics, study and application of the energy of sound waves vibrating at frequencies greater than 20,000 cycles per second, i.e., beyond the range of human hearing. Inc., Schaumberg, Ill. Ultrasonics reportedly avoid some of the limitations of adhesives, including bleed-through in thin nonwovens and heat distortion of thin films. Thus, cost savings can be realized by using thinner webs. Ultrasonic welding also opens up new capabilities such as bonding multiple layers of material simultaneously and intermittent intermittent /in·ter·mit·tent/ (-mit´ent) marked by alternating periods of activity and inactivity. in·ter·mit·tent adj. 1. Stopping and starting at intervals. 2. bonding patterns in a range of shapes. Other key benefits over adhesives include immediate bond strength and low energy costs.
