What is Ultrasonic Plastic Welding ?

Ultrasonic plastic welding is the process of joining thermoplastics by utilizing frictional heat generated by high-frequency mechanical vibrations.
This welding technique involves applying low-amplitude (1 to 250 µm) and high-frequency (15 to 30 kHz) vibrations to the workpiece using a vibrating tool known as a 'horn'.
The mechanical movement creates frictional heat at the interface of the plastic parts being joined. Consequently, the plastic material at the joint interface melts, resulting in the formation of a molecular bond between the parts.
