Technology

In orbital vibration welding the materials are placed in contact and put under pressure. An external vibration force is then applied to move the pieces relative to each other, perpendicular to the pressure being applied. The parts are vibrated through relatively small displacement amplitude, typically at 0.75 mm for a frequency of vibration of 200 Hz in the plane of the joint.

Branson informs about Orbital Vibration Welding

In orbital vibration welding the materials are placed in contact and put under pressure. An external vibration force is then applied to move the pieces relative to each other, perpendicular to the pressure being applied. The parts are vibrated through relatively small displacement amplitude, typically at 0.75 mm for a frequency of vibration of 200 Hz in the plane of the joint.

Typical welding time is 2 to 8 sec which leads to a complete cycle time of 20 to 40 sec including handling and machine movements.

Orbital vibration welding is an established technique in automotive industries and white goods. Several applications like electronic boxes, valves, ink cartridges and white goods are welded by orbital vibration machines of BRANSON.

Orbital friction welding requires more complex machinery than other techniques e.g. spin welding, but has the advantage that parts of nearly any shape can be joined as long as the joint area is flat.

Nearly every thermoplastic can be welded. Amorphous and reinforced material like Polyamide with glass fiber, even material combinations like thermoplastic with wood or textile.
