Ultrasonic welding is a technique where high-frequency ultrasonic acoustic vibrations are applied to components being held together under pressure to create a solid-state weld. The process converts high frequency energy into high frequency mechanical energy, which causes heat and friction to melt the plastic which then flows together to create a solid weld.
Typical applications for this type of welding is automotive valves and bodies, medical devices, toys, electronics and appliances as the process is very clean, fast and precise. Ultrasonic welding is often chosen when parts are too complex or expensive to be moulded in one piece.
