VIBRATION WELDING

Video shows hybrid 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.

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 componenent 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 componenent 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

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.

A quick review: The intent of the IR preheating prior to the introduction of frictional energy is fairly obvious – elevate the temperature of the weld joint. The anticipated result of this preheating is improved flash (plastic displacement from the joint) control and the potential in certain applications to reduce the necessary amplitude and/or force to achieve the ideal weld performance and assembly appearance.

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.

Hybrid welding and 4 reasons why you might need it

Have you heard the news? Extol recently partnered with CEMAS to distribute their vibration and hybrid welding machines in the US and Canada. We are thrilled to now be able to offer our customers even more plastic joining options as well as top of the line vibration and hybrid welding equipment, service, and support. Now just in case you’re thinking, “I know about vibration welding, but what is this hybrid welding thing you mentioned?” we’re going to dig into it a bit and explain why it might be a great option for your project.
