Product Description
The Herfurth UST-640 is an industrial piezoelectric ultrasonic transducer (converter) designed for use in ultrasonic plastic welding systems. Operating at 40 kHz with a 600W power rating, it converts high-frequency electrical energy from an ultrasonic generator into mechanical vibrations for applications including plastic welding, riveting, staking, and cutting. The UST-640 is a legacy Herfurth UK product — Herfurth was a leading manufacturer of ultrasonic welding equipment, and the UST-640 is compatible with generators such as the Pearl USG-624 and USG-634 series, among others. Xfurth Ltd, formed by former Herfurth UK employees, continues to supply and service this product line.
