15Khz Double Ultrasonic Welding Transducers with 8pcs 45mm Ceramics
Ultrasonic vibrator principle:
Ultrasonic transducers are actually piezoelectric ceramics whose
frequency is the same as their resonant frequency, using the
piezoelectric effect of the material to convert electrical energy
into mechanical vibration. Under normal circumstances, ultrasonic
waves are first generated by an ultrasonic generator, converted into mechanical vibration by
an ultrasonic transducer, and ultrasonic waves are generated by an
ultrasonic derivation device and an ultrasonic receiving device.
The ultrasonic transducer is the core component of the ultrasonic
device, and the ultrasonic wave converts the high frequency
electrical energy into mechanical vibration through the transducer.
The characteristics of the transducer depend on the material
selection and manufacturing process. The performance and service
life of the transducer of the same size are very different.
Commonly used high-power ultrasonic transducers are used in
ultrasonic plastic welding machines, ultrasonic metal welding
machines, various hand-held ultrasonic tools, ultrasonic emulsifier
homogenizers, atomizers, ultrasonic engraving machines, etc.

Ultrasonic transducers mainly include: ultrasonic cleaning,
industrial cleaning, industrial welding, and beauty products.
The following mainly describes the role of the ultrasonic
transducer 2.
1, ultrasonic cleaning
The mechanism of ultrasonic cleaning is to use the physical effects
such as cavitation, radiation pressure and sound flow when the
ultrasonic wave propagates in the cleaning liquid, to peel off the
mechanical phenomenon generated by the dirt on the cleaning member,
and at the same time to promote the chemical reaction between the
cleaning liquid and the dirt. Reaction, to achieve the purpose of
cleaning the object. The frequency used by the ultrasonic cleaner
can be selected from 10 to 500 kHz depending on the size and
purpose of the cleaning object, and is generally 20 to 50 kHz. As
the frequency of the ultrasonic transducer increases, a Langevin
oscillator, a longitudinal vibrator, a thickness vibrator, and the
like can be used. In terms of miniaturization, there are also
radial vibrations and bending vibrations using a disk oscillator.
Ultrasonic cleaning is used more and more widely in various
industries, agriculture, household equipment, electronics,
automotive, rubber, printing, aircraft, food, hospital and medical
research.
2, ultrasonic welding
Ultrasonic welding has two major categories: ultrasonic metal
welding and ultrasonic plastic welding. Among them, ultrasonic
plastic welding technology has been widely used. It uses ultrasonic
vibration generated by the transducer to transmit ultrasonic
vibration energy to the weld zone through the upper weldment. Since
the welding zone, that is, the sound resistance at the junction of
the two weldments is large, local high temperature is generated to
melt the plastic, and the welding work is completed under the
contact pressure. Ultrasonic plastic welding facilitates the
welding of parts that cannot be welded by other welding methods. In
addition, it also saves expensive mold costs for plastic products,
shortens processing time, improves production efficiency, and is
economical, fast, and reliable.
