 Specification:

Working Principle:

The principle of ultrasonic welding machine is generated by the generator 20kHz high-voltage, high-frequency signal, through the transducer system, the signal is converted into high-frequency mechanical vibration, added to the plastic workpiece, through the surface of the workpiece and in the friction between the molecules and the interface to the interface to the temperature rise, when the temperature reaches the melting point of the workpiece itself, so that the interface of the workpiece quickly melted, and then fill the gap between the interface, when the vibration stops! When the vibration stops, the workpiece is cooled and shaped under a certain pressure, and the purpose of welding is achieved. When the vibration stops, the workpiece is cooled and shaped under a certain pressure at the same time, then the purpose of welding is achieved. The ultrasonic welding machine transmits ultrasonic energy to the welding zone through the upper part of the weldment. Due to the high acoustic impedance of the welding zone (i.e. the interface between the two welds), a localised high temperature is generated. And because of the poor thermal conductivity of plastic, a moment can not be distributed in a timely manner, gathered in the weld area, resulting in contact with the surface of the two plastics rapidly melted, coupled with a certain amount of pressure, so that it fused into one. When the ultrasonic stop acting, so that the pressure continues, there is a little insulation time, so that the solidification of the shape, thus forming a solid molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of the raw material body.
