Product Description
The Herfurth UST 640 is an industrial piezoelectric ultrasonic transducer (converter) designed for use in ultrasonic plastic welding, riveting, and cutting systems. Operating at 40 kHz with a rated power of 600W, it forms part of the ultrasonic stack assembly — converting high-frequency electrical energy from a generator into mechanical vibrations delivered to the sonotrode/horn. This is a legacy product originally manufactured by Herfurth UK Ltd, which ceased operations in 2002; support and servicing is now available through successor companies such as Xfurth Ltd.
