Sonotrodes - Import export

The ultrasonic riveting makes possible an interlocking bonding of two thermoplastics or of thermoplastics with dissimilar materials, e. g. thermoset materials or metals. In this process the sonotrode serves as a re-forming tool. It determines the forming of the riveting pin. During the holding time (cooling phase) the sonotrode serves also as fixation stamp, thus the melted material cools down under pressure.
