Ultrasonic Riveting

Joining/Gluing: FRIMO Ultrasonic Riveting

Riveting can be useful in situations where, for example, small components must be joined to form one large component. Many different riveting methods are used, depending on which materials must be processed.

In ultrasonic riveting, the plastic is plasticised at the contact point with the sonotrode by selectively converting sound energy into heat. The plastic is then formed under pressure and pressed down. It is cooled through both the sonotrode and cooling air.
