Sonotrodes are metallic tools that are placed in a high-frequency mechanical vibration. Through contact with the workpiece or foils and fabrics etc. vibrational energy is used to make permanent connections or as in the food industry to separate products.

The designing, dimensioning and manufacturing of sonotrodes is decisive for the welding result.


In the development and manufacture of sonotrodes we now have decades of experience.


To improve understanding of ultrasonic welding, we have written a small brochure Lousy waves. In it the main fault of horns and in the welding process are described.
