Ultrasonic Cutting of Composite Materials
Since the early 90s, our sister company SONIMAT has gain a long and rich experience using ultrasonic technology for assembly, welding and cutting applications.
Ultrasounds are mechanical vibrations similar to those produced by any musical instrument. These vibrations are called ultrasound because they are at a frequency higher than the hearing capacity of the human ear (more than 16 kHz). These pressure waves are produced by a generator.
The generator sends an alternating current having the same frequency as the converter (or transducer) composed of piezoelectric ceramic which transforms it into mechanical vibrations. A voltage is sent on the ceramic and the latter “elongates” or “shortens” according to the polarity of the voltage. Once the vibration is produced, it is then amplified and transmitted to the parts to be welded or cut by the sonotrode.
