Ultrasonic welding transducer is an energy conversion device, and its performance description and evaluation require many parameters.The characteristic parameters of the transducers include resonance frequency, frequency bandwidth, electromechanical coupling coefficient, electroacoustic efficiency,

Piezoelectric 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 zon

Is the mold in operation in a normal state, and the various parts of piezoelectric ultrasonic welding transducer. such as the guide post, the ejector pin, and the row position are worn, is the lubrication good? It is required to add oil at least 12 hours, and the special structure should increase th

Piezoelectric ultrasonic transducer means that the vibration frequency is greater than 20KHz, and the number of vibrations per second (frequency) is very high, which exceeds the upper limit of the human ear (20000Hz). People call this inaudible sound wave ultrasonic. Ultrasound and audible sound are
