Description

Technical Field

[0001] This utility model relates to the field of ultrasonic welding technology, and more specifically, to a dual-head ultrasonic welding device for automotive interiors. Background Technology

[0002] Ultrasonic welding technology is a process that uses high-frequency ultrasonic vibrations to generate frictional heat to fuse materials. It is mainly used for the efficient joining of thermoplastic products. Its principle is to convert electrical energy into mechanical vibration through a transducer, causing frictional heat to be generated between molecules at the contact surface. After pressure is applied and cooling is completed, a strong weld is formed. It features the advantages of requiring no adhesives, high efficiency, and environmental friendliness.
