Ultrasonic Welding

We integrate ultrasonics into custom automation equipment.

What is ultrasonic welding?

Ultrasonic welding uses high-frequency vibration to melt and weld plastic. A tool vibrates at ultrasonic frequencies and causes concentrated molecular vibration in the weld joint. The friction between the molecules heats and melts the plastic. Once the vibration is stopped, the tool maintains a holding pressure on the joint to create a bond.

Alternatives to Ultrasonic Welding

Did you know that there are several alternative technologies to weld plastic parts? Ultrasonic welding has its place but isn’t always the best method. Other plastic welding technologies are cleaner, stronger, and safer, depending on the application.

Check out our breakdown of all the various plastic welding technologies to choose from:

What is the difference between vibration and ultrasonic welding?

Occasionally people will confuse vibration welding and ultrasonic welding because both processes use vibratory energy to weld plastic assemblies. However, both processes are very different from each other. Let’s look at the differences between the two processes and how you can use them to your advantage.
