Vibration Welding

...and HYBRID vibration welding

What is vibration welding?

Vibration welding is the process of welding two plastic parts together using linear vibration. A weld rib or bead on one component is vibrated in shear against another component. Heat is generated from friction causing the weld rib to melt. Vibration is stopped and the parts are clamped together until they bond to one another.

What is hybrid vibration welding?

Hybrid vibration welding adds an infrared (IR) preheat to the beginning of the cycle to soften the rib and reduce the amount of particulate flash generated from the vibration cycle.

The Vibration Welding Process

Clamp

The components are clamped together.

Vibrate

The upper component is vibrated against the lower component, generating friction and heat.

Cool

Vibration stops and clamp pressure is maintained until the weld cools.

The Hybrid Vibration Welding Process

Preheat

Two components are brought near an infrared heating element to preheat the weld joint.

Clamp

The infrared heating element is retracted, and the components are clamped together.

Vibrate

The upper component is vibrated against the lower component, generating friction and heat.

Cool

Vibration stops and clamp pressure is maintained until the weld cools.

The energy in vibration welding

The energy in vibration welding

Recently, we’ve been discussing conventional vibration welding and hybrid or ‘clean’ vibration welding. Vibration welding, a linear frictional weld method, you probably know all about. Hybrid – the introduction of an infrared preheat function prior to the conventional vibration weld process, is a relatively new method of welding plastic parts.

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.
