ULTRASONIC WELDING TRANSDUCERS
The ultrasonic transducer, also commonly referred to as a converter, converts high frequency electrical vibrations into a mechanical longitudinal vibration with a constant output amplitude.
Depending on production environment conditions, ultrasonic converters are available with protection ratings of IP50, IP65, and IP67. For rotating operation, a series of ultrasonic converters with integrated HF connection for rotary couplers has been developed.
What all ultrasonic welding converters have in common is their central assembly with solid piezoceramic four-disk technology. Between each of the disks is a thin metal plate. This forms the electrode, which feeds the transducer with a sinusoidal electrical signal. As they receive the signal, the discs expand and contract, which produces resonant mechanical motion. The rigid decoupling principle allows for axial and transverse forces. When used in conjunction with boosters and sonotrodes, the energy generated is transmitted to thermoplastic work pieces to weld them together. These piezoelectric devices also can be used on materials that require this unique type of energy to undergo chemical or physical changes. Special manufacturing processes ensure extremely long service life at constant output amplitude.
Herrmann Ultrasonics is the leader when it comes to piezoceramic transducers and other components used for ultrasonic welding. In addition to these ultrasonic welding transducers, we also manufacture ultrasonic boosters to enhance their mechanical output to produce more amplitude, which can deliver more power to the workplace. Our product line also features a wide assortment of sonotrodes, which are often the custom tools made to directly contact and apply ultrasonic energy to the part.
No matter what you require for your operations, you can depend on us to provide you with high-quality components and systems. Our products are designed and engineered to deliver the maximum levels of performance in every respect.
