Ultrasonic Spot Welder generator 28khz/30khz/35khz/40khz

The principle of ultrasonic spot welding is that the generator generates 15 KHZ-100 kHz high-voltage and high-frequency signals. Through the ultrasonic energy transfer system, the ordinary electrical signals are converted into high-frequency mechanical vibration. By means of the welding head, the energy is transmitted to the plastic workpiece, so that the internal molecule of the ultrasonic spot welding generates intense friction and heat. When the temperature reaches the melting of the workpiece itself. At point, the workpiece interface melts rapidly and at the same time the vibration stops, it is formed by compression cooling to achieve perfect welding. Research shows that the use of ultrasonic spot welder in plastic industry has become increasingly common around the world. Because this technology can replace the flux, adhesive, fastener or other mechanical fixing method needed in the past production, the production efficiency is improved and the cost is reduced. The welding principle of ultrasonic spot welding machine is that the generator generates high-voltage and high-frequency signals of 20KHz (or 15KHz). The signals are converted into high-frequency mechanical vibrations through a transducer system. The signals are added to the workpiece of plastic products. The temperature of the transmission point to the interface is raised by friction between the surface and the inner molecules of the workpiece. When the temperature reaches the workpiece. At its melting point, the workpiece interface melts rapidly, and then fills in the gap between the interfaces. When the vibration stops, the workpiece is cooled and shaped at a certain pressure, and the perfect welding is achieved.
