Sonics Introduces new 30 kHz Ultrasonic Welding Systems


Sonics & Materials, Inc. introduces its new 30 kHz Ultrasonic Plastics Welding Systems featuring the Model 3050 bench top press. The 30 kHz frequency is particularly suitable for applications where both power and Class A surface cosmetics are important considerations. At 30 kHz frequency, the Model 3050 Press offers front panel pneumatic speed and pressure controls with a direct in-line air cylinder. The microprocessor-controlled power supply provides consistent reliability with features such as digital amplitude control; ultrasonic horn / stack frequency display; good part / bad part output signal; and a 30% smaller power supply footprint. The 3050 ultrasonic welding system is available in 1200 watts power and in 3 weld modes (weld by digital time; digital time or constant energy; or digital time, constant energy or distance). Additional standard features include automatic frequency tuning, multiple job storage, digital force triggering, calibration pulse, ultrasonics load meter scale and upper/lower weld limit settings. The benchtop press features a single piece rigid cast aluminum machine base and hub with in-line load cell for precise force triggering; single rail linear slide and 360 degree converter alignment. An optional linear encoder for distance welding is available. Additional 30 kHz systems include the Model 3055 bench top press and the Model 3096 self-contained slimline actuator.
