Custom made Rinco replaced ultrasonic welding transducers for
Ultrasonic welding is an industrial technique whereby
high-frequency ultrasonic acoustic vibrations are locally applied
to workpieces being held together under pressure to create a
solid-state weld. It is commonly used for plastics, and especially
for joining dissimilarmaterials. In ultrasonic welding, there are
no connective bolts, nails, soldering materials, or adhesives
necessary to bind the materials together.
For joining complex injection molded thermoplastic parts,
ultrasonic welding equipment can be easily customized to fit the
exact specifications of the parts being welded. The parts are
sandwiched between a fixed shaped nest (anvil) and a sonotrode
(horn) connected to a transducer, and a ~20 kHz low-amplitude
acoustic vibration is emitted. (Note: Common frequencies used in
ultrasonic welding of thermoplastics are 15 kHz, 20 kHz, 30 kHz, 35
kHz, 40 kHz and 70 kHz). When welding plastics, the interface of
the two parts is specially designed to concentrate the melting
process. One of the materials usually has a spiked energy director
which contacts the second plastic part. The ultrasonic energy melts
the point contact between the parts, creating a joint. This process
is a good automated alternative to glue, screws or snap-fit
designs. It is typically used with small parts (e.g. cell phones,
consumer electronics, disposable medical tools, toys, etc.) but it
can be used on parts as large as a small automotive instrument
cluster. Ultrasonics can also be used to weld metals, but are
typically limited to small welds of thin, malleable metals, e.g.
aluminum, copper, nickel. Ultrasonics would not be used in welding
the chassis of an automobile or in welding pieces of a bicycle
together, due to the power levels required.

The transducer is an energy converter, which can converted the high
frequency, high power current, output of power supply into
reciprocating mechanical energy of the ultrasonic vibration, the
vibration frequency output of drive power with the same frequency
as the current. To further enlarge the amplitude of ultrasonic
energy input to the place where we need.
These products are widely used in various fields ,such as plastic
welding ,rubber cutting ,non-woven welding and so on.
The transducer converts high-frequency electrical energy into
high-frequency mechanical vibrations. And it contains several
piezoelectric ceramic discs sandwiched under pressure between two
metal blocks. Between each disc is a thin metal plate, which forms
the electrode. When a sinusoidal electrical signal is fed to the
transducer via the electrodes, the discs expand and contract,
producing axial vibrations.
15Khz transducer widely used in high power welding&sealing
system.Piezoelectric transducer is the electric charge that
accumulates in certain solid materials in response to applied
mechanical stress. It is key point of all ultrasonic equipment.The
transducer decide the property of the machine.We can supply
transducer, also transducer with house and booster.
To design and fabricate the transducers according to customers'
1. The piezoelectric ceramic chip adopts imported parts, and can
give a strong and stable output.
2. High efficiency, high mechanical quality factor, obtaining high
electric-acoustic conversion efficiency work at the resonance
3. Large amplitude: optimization design by computer , vibration
speed ratio is high .
4. Large power,Under the action of prestressed screw, the energy of
the piezoelectric ceramic to get maximum play;
5. Good heat resistance, small harmonic impedance, low calorific
value, using temperature range is wide.
