Ultrasonic transducer is a device that can convert high-frequency electrical energy into mechanical energy. It is generally magnetostrictive and piezoelectric ceramic. The power output is sent to the ultrasonic generator, and then to the ultrasonic transducer. The ultrasonic derivation device can generate ultrasonic waves.
The ultrasonic transducer consists of a central piezoceramic component, a front and rear metal cover, a pre-stressed screw, an electrode pad and an insulating tube. This sandwich transducer (also known as a bolt-on transducer) produces a load change. Stable ultrasonic is the most basic and most important method to obtain power ultrasonic drive source.
According to different designs, the shape of the ultrasonic transducer mainly has a column type (the front and rear metal cover plates have the same diameter) and a horn type (the front cover plate diameter is excessively reduced by the arc shape).

Problems that can arise when using ultrasonic transducers:
Common problems in use are wafer cracking, weakness, overload, electrode pad ignition, electrode chip cracking, heat generation, leakage, and wafer misalignment.
The reasons for such problems can be classified into three categories. One is that the customer's drive power or mold and assembly problems, the second is that our transducers and horns have problems, the third is that both products have no problem, but do not match.
1. our ultrasonic transducer and horn have problems
This will happen, but the possibility of discovery is relatively small. Our company specializes in producing all kinds of high-power ultrasonic transducers. The quality of all products of the horn is at a high level in China. At the same time, we have ISO9000 quality certification system and strict process and inspection. The quality of our ultrasonic transducer products is guaranteed. The pass rate of our factory products is 100%.
2. the customer's drive power or mold has a problem
We recommend that customers actively find the cause or communicate with our technical staff to improve as soon as possible.
3. the products of both parties have no problem, but they do not match.
This is the most common, that is, the customer's drive power is good, the ultrasonic transducer is also good, the assembly is normal, but the parts do not match. The main parameter causing the mismatch is the frequency and capacitance of the ultrasonic transducer. In response to this situation, the solution is to adjust the matching parameters of the driver's power supply to suit our ultrasonic transducers. The second method is to carefully study the various chassis and the original transducers. Parameters, in summary, as long as you can provide accurate parameter requirements, we can guarantee to provide you with the right transducer.
