Ultrasonic plastic welding is a kind of welding technology where current is converted into a high-frequency electric energy by the ultrasonic generator. It is the joining or reforming of thermoplastics through the use of heat generated from high-frequency mechanical motion. Ultrasonic welding of plastic materials creates a molecular bond within the weld seam.
Ultrasonic welding is a process used to join two plastic parts together to form a strong, finished assembly. The process relies on high-frequency (ultrasonic) vibrations being generated and applied to the parts via a horn. Welding occurs as the vibrations are absorbed in the interface between the two parts, generating friction and causing the plastic to melt. The ultrasonic vibrations are generated by a series of components, including the power supply, converter, booster and horn, which ultimately delivers the mechanical vibration to the parts.
