Model: ST 15/ STP 15/ ST20/ STP20


  • Stop oscillation at the preset position (Unified height of welded products)

    Ultrasonic oscillation can be stopped when the preset welding depth is reached. This can compensate the difference of injection and so as to raise the quality of welded products.

  • Equipped with a Sonic Regulator

    With this, an operator can find the best resonance of oscillation system easily.

  • Roller Guide Rails is installed

    Roller Guide Rails are more stable than ball-screwed or ball bearing guide rails. No risks of deflection or vibration problem during dowm stroke movement. The most suitable unit for welding the non-flat and/or curved surfaces.

  • Easier retooling and adjusting

    The horizontal adjustment studs enable a precise alignment of the clamping table and fixture. Even the horn is replaced, no more adjustment is needed for horn and fixture.

  • Special design of circuits

    high output and long service life. It can complete the welding within seconds.
