Working Principle: Uses high-frequency ultrasonic vibrations (typically 20–40 kHz) to create heat through friction, melting and bonding thermoplastic materials at the molecular level.
Handheld Design: Compact and portable, making it suitable for spot welding, riveting, and embedding.
Controller Unit: The yellow box contains the ultrasonic generator (power supply) that converts standard electrical power into high-frequency ultrasonic energy.
Welding Horn (Sonotrode): The front tool (wrapped in plastic) delivers the ultrasonic energy to the material.
Applications:
Joining plastic parts
Riveting and spot welding
Embedding metal parts into plastics
Cutting and sealing synthetic fabrics
Advantages:
No need for adhesives, screws, or solvents
Fast, clean, and strong bonding
Precise and consistent results
