High Stability 20kHz Ultrasonic Transducer for Precision Plastic Welding
Ultrasonic transducer is the key part of ultrasonic machine. It is a device mainly convers high-frequency electric energy into mechanical vibration.
Introduction:
Ultrasonic transducer consists of a stack bolt, back driver, electrodes, piezoceramic rings, a flange and a front drive. The piezoceramic ring is the core component of the transducer, which converts high-frequency electrical energy into mechanical vibration.
At present, ultrasonic transducers have been widely used in industry, agriculture, transportation, life, medical, military and other industries. Ultrasonic transducer is the key part of ultrasonic machine, and its quality directly affects the quality of the whole machine.

Advantage:
2.Energy saving and environmental protection. It is made of piezoelectric ceramic material, which has high conversion efficiency and can be mass-produced. 3.The performance of piezoelectric materials varies with time and pressure, so taking some time to test can identify non-conforming materials is necessary. All of our ultrasonic transducers will be aged before testing and final assembly. 4.One by one testing to ensure that each transducer performance are excellent before shipping. 5.Customization service is acceptable. | ![]() |
