BLTW

BLTW Ultrasonic plastic welding transducers

Plastic welding transducers for all applications

A versatile range of high power and high efficiency ultrasonic converters of the well known half-wave design (also known as "sandwich" or "Langevin" transducers). Each resonator system comprises a prestressed metal/piezoelectric ceramic/metal sandwich, especially suitable for high power plastic welding, ultrasonic machining and liquid processing.

BLT-series transducers use Poreless Piezo Ceramic for its superior mechanical and electrical properties (click the link for more details).
