Ten Questions About Piezo Discs And Cylinders You Should Answer Truthfully

There is not much difference between piezoelectric sensor crystaltransducers used for metal ultrasonic welding equipment and those are used for plastic ultrasonic welding equipment. The particularity piezo film is that the welding metal material has higher quality requirements because the welding metal material often needs a large Of the instantaneous power requirements of the working piezoelectric sensor transducer ,they have high power capacity and low impedance, so low-power transducers for plastic ultrasonic welding devices can not be used for metal ultrasonic welding.Ultrasonic welding can be applied to metal welding, ultrasonic welding technology that put forward higher requirements, compared to ordinary plastic welding, piezoelectric power generation is used on the power capacity, stability and automation control and other aspects have put forward higher requirements . Most domestic companies are the existing ready-made equipment for plastic welding and mature technology directly onto the metal welding, but due to the power of plastic welding machine can not be used for piezoelectric detector, thick metal plate can only be used Thin metal foil seam welding, such as rolling welder, its technical deficiencies, leading to product performance instability. The only advantage of this plastic welding arrangement for humidity sensor is that it is inexpensive, but it does not meet the high requirements of metal materials for welding and can not be widely used in metal welding.Now the domestic ultrasonic plastic welding generator used are basically self-excited circuits, circuits and equipment commonly used in Taiwan half-bridge circuit, the main use is of inductive tuning. Ultrasonic metal welding for piezoelectric transducer datasheet requires a more stable generator, which firstly requires the automatic tracking of frequency, but at present, there are only a few manufacturers that really master the automatic tracking technology of high-power applications in China.
