Ultrasonic assembly utilizes an acoustic tool called a horn to transfer
vibratory energy through the part to the joint area, where it is
converted to heat through friction that melts the plastic. Ultrasonics
can be used to join not only rigid thermoplastics, but fabrics and
films as well.

ultrasonic welding equipment converts 50/60 Hz current to 15, 20, 30,
or 40 kHz electrical energy through a solid-state power supply. This
high frequency electrical energy is supplied to the converter that
transforms it to mechanical motion at ultrasonic frequencies. The
mechanical motion is then transmitted through an amplitude-modifying
booster to the horn. The horn, an acoustic tool, transfers this
vibratory energy directly to the parts being assembled.
The
main components of an ultrasonic system are the power supply,
converter/booster/horn stack, part fixture, and a means of providing
horn contact with the parts -- usually an actuator.
Four frequencies of ultrasonic equipment are available to accommodate your application requirements.
Shown from left to right: 15 kHz, 20 kHz, 30 kHz, and 40 kHz.
