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.

Extol named distributor of CEMAS hybrid vibration welding technology in United States and Canada

Extol and CEMAS have reached an agreement that appoints Extol as the sole distributor of CEMAS’s exceptional vibration and hybrid vibration welding machines in the United States and Canada. Effective today, customers in the US and Canada will be able to purchase from CEMAS’s wide selection of vibration welding machines through Extol. In addition, Extol will build and provide tooling, stock and supply spare parts, and offer service and support.

Vibration vs. Hot-Plate Welding

We all love options – colors, cars, hobbies, music, and of course our favorite, plastic welding!
Let’s talk about a few of the differences between vibration and hot plate welding that may help in discerning when to choose one over the other. Ah, but first we should briefly review the two welding processes.
