Ultrasonic metal welding machine process analysis, ultrasonic welding is the use of high-frequency vibration waves transmitted to the surface of two objects to be welded, in the case of pressurization, so that the two surfaces of the object friction with each other to form a fusion between the molecular layers, ultrasonic waves can not only be used to weld hard thermoplastics
Ultrasonic welding is a high-tech technology for welding thermoplastic products, all kinds of thermoplastic parts can be treated with ultrasonic welding without adding solvents, adhesives or other auxiliary products.
Its advantages are to increase multi-fold productivity, reduce costs, improve product quality and safe production Ultrasonic plastic welding principle is generated by the generator 20KHz (or 15KHz) of high-voltage, high-frequency signal, through the transduction system, the signal is converted into high-frequency mechanical vibration, added to the plastic product workpiece, through the workpiece surface and friction between the molecules and the temperature transmitted to the interface increases, when the temperature reaches the melting point of the workpiece itself, the workpiece interface is quickly melted, and then filled in the gap between the interfaces, When the vibration stops, the workpiece is cooled under pressure at the same time, and the weld is achieved.
