2000W 20K Auto Line Industrial Ultrasonic Disposable  Foam Face Mask  Ear Loop Ultrasonic Welding Transducer

Ultrasonic waves are transformed into mechanical vibrations through transducers. The characteristics of transducers depend on material selection and manufacturing process. The performance and service life of transducers of the same size and shape are very different. The commonly used high-power ultrasonic transducer is used in ultrasonic plastic welding machine, ultrasonic metal welding machine, various handheld ultrasonic tools, continuous working ultrasonic emulsifier, atomizer, ultrasonic engraving machine and so on. Commonly used products such as 15KHz 20KHz 28KHz 35KHz 40KHz 55KHz 70KHz can also design and produce non-standard transducers according to the special requirements of customers to meet all kinds of needs.The ultrasonic vibrator is also called the ultrasonic vibrator, and the whole after connecting the transducer and the horn is called the vibrator. It is a device that realizes the mutual conversion between electrical energy and mechanical energy (acoustic vibration) by the piezoelectric effect of piezoelectric ceramics, and amplifies the device through the front and rear radiation cover blocks matched with acoustic impedance. [1]
Since the horn is a passive device, it does not produce vibration itself, but transmits the input vibration after changing the amplitude, completing the impedance transformation.
Ultrasonic transducers can produce regular vibration under the excitation of electric field, but the amplitude is generally about 10μm. Such amplitude is not enough to directly complete the welding and processing procedures.
Therefore, after the transducer is connected with a reasonably designed horn, the amplitude of the ultrasonic wave can be changed in a large range, as long as the material strength is sufficient, the amplitude can exceed 100 μm.
