The composition of ultrasonic transducers
Almost all piezoelectric transducers used for power ultrasound are of the Langevin type, that is, one or more piezoceramics are mechanically compressed (pre-stressed) between a front driver and a rear driver.
Ultrasonic transducers consist mainly of central piezoceramic elements, front and rear metal covers, prestressed bolts, electrode sheets, and insulating tubes, as detailed in the diagram below. Nearly all piezoelectric transducers used for power ultrasound are of the Langevin type, which involves one or more piezoceramic elements being mechanically compressed (pre-stressed) between a front driver and a rear driver.

The precision of these welds is unmatched; we finally achieved the clean, hermetic seals we needed for our sensitive medical device components without any heat distortion.
We were up and running the same day it arrived; the intuitive controls made it simple for our team to start producing perfect welds on our plastic prototypes with no prior experience.
