The Mini II vibration welder has the smallest footprint in the industry (2' x 4'), yet offers all of the advantages of the vibration welding process with enhanced performance, ease of operation and added serviceability features.

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.
