Ultrasonic welding is one of the most common methods of assembling two thermoplastic parts. Ultrasonics provides strong, reliable bonds at very fast cycle times. A single ultrasonic welder can be used to join parts up to approximately 8" in diameter, but several welders can be combined or “ganged together” to weld larger parts.

An ultrasonic welding system generally consists of two major components. The first is the power supply, which converts 60 cycle electric power to high frequency (generally 20,000 cycle) electrical energy. This unit may also contain process controls for the welder. The second unit houses the elements
