Almost 100 experts from Germany and abroad came together in Ettlingen on October 22, 2026, for the first 360° Ultrasonics Technology Forum hosted by Weber Ultrasonics AG. The technical presentations and demonstrations focused on cavitation physics, simulation-assisted process optimization, and new industrial applications. Other key topics included megasonic technology for semiconductor, optics, and wafer cleaning, as well as the new strategic partnership with Japan’s Kaijo Corporation. The direct exchange between system integrators, users, researchers, and technology experts provided an opportunity for technical discussions and new application approaches.

Changing components, production conditions, and cleanliness requirements are presenting industrial ultrasonic cleaning with new challenges. The first 360° Ultrasonics Technology Forum hosted by Weber Ultrasonics AG on October 22, 2026, in Ettlingen demonstrated the technical approaches available to address these challenges and the applications that can be opened up beyond conventional cleaning. Almost 100 experts from Europe, Asia, and the USA attended. The new strategic partnership with Kaijo Corporation’s Ultrasonic Division was presented. The Japanese company’s megasonic portfolio ranges from 200 kHz to 3 MHz and includes solutions for precision cleaning as well as batch and single-wafer cleaning in the semiconductor industry. It complements Weber Ultrasonics’ range of solutions in the high-frequency range.

Cavitation – topic of the day

In addressing the topic of the day, cavitation, the speakers covered everything from the physical fundamentals and expertise on the cleaning effects of cavitation bubbles to potential damage to component surfaces. Other presentations focused on the modeling, control, and optimization of cavitation processes using simulation, as well as online monitoring with measurement systems from Onda. Weber Ultrasonics aims to establish simulation-assisted methods as a standard tool for the industrial design and optimization of ultrasonic cleaning systems. The applications of rod transducers and the new Sonopower 4S generator family were also on the agenda.

Ultrasound is also effective beyond cleaning

Examples from process engineering and current research projects demonstrated the wide range of applications for ultrasound beyond cleaning. The spectrum ranged from the emulsification of diesel and ethanol, through ultrasound-assisted zeolite synthesis and textile processing, to the recycling of lithium-ion batteries and valuable materials from carbon-fiber-reinforced composites. The Swiss company Ultrom also presented a practical example from brewing technology.
The event concluded with a discussion about the future of industrial ultrasonic applications from the customer’s perspective.

The high number of participants and the very positive feedback from visitors to Weber Ultrasonics’ first 360° Ultrasonics Technology Forum suggest that the event will continue.
