SP TECH offers a large number of converter types in order to achieve the best results for each application. The converters transform the electrical oscillations produced by the ultrasonic generator into mechanical sound waves.

Ultrasonic converters are fitted with 2, 4 or 6 ceramic discs, depending on the application. The latter are predominantly used in the packaging industry and for continuous use. The oscillations are best transferred to the ultrasonic workpiece through the ceramic discs, thereby reducing process times and ensuring high process reliability. The top quality housings are very strong and long-lasting and have various HF interfaces.
