28KHZ 500W Ultrasonic Welding Machine Spot Welder Plastic Transducer Customize Converter replacement

Ultrasonic welding transducer is one of the important parts of ultrasonic vibration system in ultrasonic processing equipment. In the working process of the ultrasonic vibration system, because the vibration amplitude generated by the radiation surface of the ultrasonic transducer is small, when the working frequency is within 20 khz, the amplitude of the radiation surface of the ultrasonic transducer in ultrasonic welding is only a few microns, and the required amplitude is about tens to hundreds of microns. Therefore, it is necessary to amplify the displacement and moving speed of mechanical vibration particles with the help of ultrasonic welding transducers, and concentrate the ultrasonic energy in a small area to produce energy collection effect. The ultrasonic welding transducer can also be used as a mechanical impedance converter to bridge the impedance matching between the sensor and the load, so that the ultrasonic can be transmitted from the sensor to the load more effectively. 2 Ultrasonic transducer system design The transducer system design of ultrasonic plastic welding machine mainly includes three parts: ultrasonic transducer, ultrasonic welding transducer and welding head
