Abstract

An ultrasonic systems and methods for sealing complex interfaces or for metal forming. Complex interfaces, such as a Gable top, have multiple and a variety of layers across the interface, or an oval or round spout having a complex geometry. An example system includes two ultrasonic horns arranged opposite a gap between which the interface is provided. The frequency and phase of the ultrasonic energy are synchronized as the energy is applied simultaneously while the interface is pressed between a jaw and the energy is applied to both sides of the interface. Another example system includes two ultrasonic transducers synchronized in frequency and phase and used to vibrate a horn mechanically to facilitate a sealing or welding interface or to assist in a metal-forming process.
