Often people mistake vibration welding for ultrasonic welding and vice versa. This is because both methods utilize vibrational force to weld plastic assemblies. However, the reality is that both these welding techniques are very different from each other.

The vibration welding method pulsates in a linear side-to-side movement with one part proportional to another. The friction between the two parts produces the heat, which is used to perform the weld. In comparison, the ultrasonic welding method pulsates one part parallel to another, just like a jackhammer or pavement.

What are the Advantages of Ultrasonic Welding?

With the rapid speed of welding, high welding strength, and excellent sealing efficiency, the ultrasonic welding technology stands out. It is an effective substitute for conventional welding/binding methods. The method is safe because it does not use toxic chemicals or adhesives. It does not cause any damage to the product either. Additionally, this technology is easy to incorporate in the manufacturing process and has a low failure rate. All of these benefits can help reduce the cost of production.
