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. Commonly used 15KHz 20KHz 28KHz 35KHz 40KHz 55KHz 70KHz and other products We can also design and manufacture non-standard transducers according to customer's special requirements to meet various needs.

Specifications:

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.
