Vibration Plastic Welding

Vibration plastic welding is used to join large plastic parts through frictional heat and pressure generated in a linear or orbital motion (vibration). The surface of one part is vibrated against the other, which is generally fixtured in a stationary position. Vibration welding lends itself to large or irregularly shaped parts and difficult to weld resins that do not work well with other methods. Vibration plastic welding produces high-pressure hermetic and very strong structural seals, and it is more forgiving (tolerance variations, wall thickness considerations) than most other methods.
