Ultrasonic welding

Ultrasonic is sound that accelerates down into a ”Sonotrode” (tool) resulting in a mechanical hammering effect. This pounding generates heat in most fabrics.

Ultrasonic is another technology for joining plastic materials.

The heat needs to penetrate the first layer in order to join the second layer.

Is RF Welding the Same as Ultrasonic Welding?

No, RF welding and ultrasonic welding are distinct processes. While both methods join materials, RF welding utilizes electromagnetic energy to generate heat within the material, while ultrasonic welding employs mechanical vibrations to create friction and heat.

What is the Difference Between Ultrasonic and RF Welding?

Ultrasonic welding relies on mechanical vibrations to create friction and heat, while RF welding uses electromagnetic energy to generate heat within the material itself. Additionally, ultrasonic welding may have limitations in welding multiple layers without damaging the material’s surface.

Advantages with ultrasonic welding:

+ Can be used for non-dielectric materials
+ Suitable for detailed welding

Disadvantages with ultrasonic welding:

– The technology creates a high pitch sound
– It is difficult to weld more than two material layers without damaging the surface of the material and causing burns
– The weld area is very limited and the technology is not suitable for larger applications
