An ultrasonic horn with booster is an essential assembly used in ultrasonic welding machines. It plays a key role in transferring and amplifying high-frequency mechanical vibrations from the converter to the material being welded.
The booster adjusts vibration amplitude, while the horn delivers controlled ultrasonic energy directly to the welding surface. Together, they ensure efficient energy transfer, consistent weld quality, and reliable performance in industrial applications.
⚙️ How Ultrasonic Horn with Booster Works
The ultrasonic generator produces high-frequency electrical energy, which is converted into mechanical vibrations by the converter.
🔹 The booster modifies and amplifies the vibration amplitude according to the application requirement.
🔹 The horn (sonotrode) transmits these vibrations to the material while applying controlled pressure.
This process generates localized heat through friction, allowing thermoplastic or non-woven materials to bond seamlessly.
