Ultrasonic assemblies

Efficient, safe and simple ultrasonic processes

SONOTRONIC develops individual ultrasonic assemblies for integration into existing machine concepts for various applications. Solutions such as the patented sonotrode table optimize processes through the advantages of ultrasonic technology.

Since ultrasonic technology can be used in many areas and industries, SONOTRONIC supplies on the one hand ultrasonic assemblies in addition to complete machines and systems. 

On the other hand, we also develop oscillating units as special assemblies, which are built into the customer's own fixtures. One of these special assemblies is the patented sonotrode table, in which several block sonotrodes are arranged to form a flat welding area. The design and shape of the workpieces is determined individually by the anvil embossing. The sonotrode table is mainly used in the packaging industry and realizes customer-specific applications.
