Piezoelectric Ultrasonic Converter With 2pcs Ceramics For Non Woven Fabric Welding

28Khz Piezoelectric Ultrasonic Converter with 2pcs Ceramics for Non-woven Fabric Welding

Description:

Ultrasonic welding is not radiation, it will not cause direct radiation damage to the human body. If it is harmful, it is a certain noise when ultrasonic welding plastic. The noise is different according to the frequency. The noise of 20KHZ equipment is relatively high. Smaller, the application of ultrasonic plastic welding technology in the plastics industry has become increasingly common. The use of this technology can replace the flux, adhesive, pinning or other mechanical fixing methods required in the past, thereby increasing production efficiency and reducing costs. The principle of ultrasonic welding machine is to generate 20KHz (or 15KHz) high-voltage and high-frequency signals from the generator. Through the energy conversion system, the signal is converted into high-frequency mechanical vibration, which is applied to the workpiece of plastic products and passes through the surface of the workpiece and the intrinsic molecules. Friction increases the temperature of the interface to the interface. When the temperature reaches the melting point of the workpiece itself, the workpiece interface is rapidly melted and then filled in the gap between the interfaces; when the vibration stops, the workpiece is simultaneously cooled and shaped under a certain pressure. A perfect weld is achieved.

Specifications:
