We work closely with our clients to design a machine that meets their specific welding needs, including sonotrode frequency, power output, control system and more.


We create ultrasonic welding machines tailored to the specific needs of our customers. This means that we do not have a standard product line, but create what the customer wants. We work with our customers to design the perfect machine for their particular welding application.
