Linear vibration plastic welding machine
Branson Ultrasonics
With vibration welding the plastics parts to be joined are vibrated (rubbed) against each other at a chosen frequency, amplitude and pressure which results in frictional heating of the surfaces, causing the polymer to melt at the interface. The molten polymer flows out of the weld-zone giving rise to flash. When vibration stops the weld cools down and solidifies.
Linear vibration welding uses transverse, reciprocating motion; the vibration occurs in only one axis.
