The models 1096 and 1099 are 20 kHz precision pneumatic actuators used
for ultrasonic plastics assembly. The 1099 is a tabletop version, and the 1096
can be mounted on a bridge or rigid structural member for use with automated
systems. These presses can be supplied with the following power supplies:
■ FD . . . . . . . . . . . . .Timer
■ FDL . . . . . . . . . . . . .Timer/Linear Encoder
■ FM . . . . . . . . . . . . .Microsonic Processor™

WHAT IS ULTRASONICS?
Ultrasonics refers to vibrational waves with a frequency above the human
audible range which is usually above 18,000 cycles per second (Hz).
PRINCIPLE OF ULTRASONIC ASSEMBLY
The basic principle of ultrasonic assembly involves conversion of high
frequency electrical energy to high frequency mechanical energy in the form
of reciprocating vertical motion which, when applied to a thermoplastic,
generates frictional heat at the plastic/plastic or plastic/metal interface. In
ultrasonic welding, this frictional heat melts the plastic, allowing the two
surfaces to fuse together; in ultrasonic staking or insertion, the controlled flow
of molten plastic is used to capture or lock another material in place (staking)
or encapsulate a metal insert (insertion).
ULTRASONIC ASSEMBLY SYSTEMS
“Sonics” ultrasonic assembly systems are generally composed of the
following major elements: a power supply, converter, booster, horn, pneumatic
press and holding fixture, as detailed in the diagram on the next page. A
review of this diagram will help you understand the basic elements involved in
the assembly process and their relation to each other.
