Ultrasonic Welding machine

Ultrasonic welding converts a 50/60 Hz current into 15, 20, 30, or 40 kHz electrical energy using an ultrasonic generator. This high-frequency electrical energy is then converted into mechanical motion of the same frequency by a transducer. This mechanical motion is then transmitted to the welding head via an amplitude converter. The welding head transfers the received vibrational energy to the joint of the workpieces to be welded, where the vibrational energy is converted into heat energy through friction, melting the plastic. Ultrasonic waves can be used not only to weld hard thermoplastics but also to process fabrics and films.
