Plastic Assembly Technologies, Inc. (PAT) manufactures, markets, distributes and supports ultrasonic horns, ultrasonic fixtures, protective film winders, welder tables, hot plate and spin welders, sound enclosures, ErgoStations, infrastake and infratol machines, ultrasonic SPC software and accessories. Ultrasonic welding includes use of ultrasonic plastics assembly equipment including microprocessor-controlled bench-top welders, remote actuators and ultrasonic kits for automation, and hand-held plastics welders. Vibration plastic welding is used to join large plastic parts through frictional heat and pressure generated in a linear or orbital motion. Hot plate plastic welding is generally used to weld large and irregular shaped plastic parts with difficult contours and joint lines. Sonic welding means the same as ultrasonic welding.

Branson Ultrasonics offers plastics joining processes/products, including ultrasonic, vibration welding, laser IRAM welding, hot plate welding, spin welding, textile and film sealing. ultrasonic welder can involves the use of Ultrasonic Hand Guns, Bench Top Integrated Ultrasonic Welders, Automation Ultrasonic Actuator Heads and Modular Power Supplies. Ultrasonic welders has closed Loop Process Controls in Energy Welding, Distance Welding, Time Welding, Force Welding, Automatic Frequency Tuning, and Variable Amplitude Output Control. Ultrasonic transducers convert electrical energy to mechanical energy via piezoelectric vibrators. Plastic Assembly Technologies provides ultrasonic testing for flaw detection - evaluation, dimensional measurements and material characterization.
