POWER SUPPLY/GENERATOR – The built-in solid state power supply
converts standard 50/60 Hz electrical power to 20,000 Hz electrical energy
(20 kHz).
ACTUATOR/PRESS – The pneumatic actuator provides compressive force
and mounting for the converter, booster, and horn assembly. The benchtop
press consists of a base assembly, column and actuator (head).
CONVERTER – The converter changes the high frequency electrical energy
supplied by the power supply to high frequency mechanical vibrations.
BOOSTER – Successful ultrasonic welding often depends on having the
right amplitude at the horn face. Often it is not possible to design a horn
which has both the necessary shape and required gain (ratios of input
amplitude to output amplitude). Therefore, a booster is placed between the
converter and the horn to either increase or decrease the amplitude of the
horn. In addition to changing/maintaining the amplitude, the booster
provides support and alignment in the welding system. (See page 27 for
booster selection.)
HORN – The horn is a tuned component of the system which comes in
contact with the parts to be assembled. The horn 1) transfers the ultrasonic
vibrations produced from the converter to the parts being welded, and 2)
applies necessary force to the assembly while the material resolidifies.
HOLDING FIXTURE – The holding fixture or nest assures proper alignment
and support of the parts being assembled.
