EWI has broad capabilities in high power ultrasonics (HPU), a technology based on the principal of converting electrical energy into mechanical energy for the purpose of changing the physical, chemical, or biological properties of materials or systems.

While most industrial applications utilize frequencies within the 20-50 kHz range, there are applications that require frequencies as low as 10 kHz and as high as 100 kHz. Power requirements, therefore, can vary from tens to thousands of watts.

Key benefits of HPU include friction reduction, solid state bonding, extremely fast cycle times, and real-time feedback. EWI’s advantage lies in our extensive equipment for measurement and diagnostics of HPU systems, and in our highly skilled technologists who are experts in:

  • Ultrasonic Metal Welding
  • Ultrasonic Additive Manufacturing
  • Ultrasonic Machining
  • Ultrasonic Plastic Welding
  • Ultrasonic Brazing Soldering
  • Plastics Joining Processes
  • Microjoining Processes
