Sonotrodes are weld tools that are specifically developed and calculated for each application. In case of damage, a new sonotrode must be produced, tested, and documented, including all finishing processes. This requires time. If you have a spare sonotrode in stock, you can avoid expensive standstill times in production.

We provide a particularly interesting offer for our customers at very attractive terms if they order a spare sonotrode within the first three months upon delivery of their ultrasonic welding machine or their ultrasonic welding system.
