Working Principle:

Ultrasonic welding machine principle is generated by the generator 20KHz of high pressure, high-frequency signals, through the transducer system, the signal is converted into high-frequency mechanical vibration, added to the plastic products on the workpiece, through the surface of the workpiece and in the intermolecular friction and so that the transfer to the interface of the temperature rises 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, and when the vibration stops, the workpiece cooled and shaped under a certain pressure, it will achieve the purpose of welding. When the vibration stops, the workpiece at the same time in a certain pressure cooling and shaping, will achieve the purpose of welding. The ultrasonic welding machine transmits ultrasonic energy to the weld zone through the upper weldment, due to the high acoustic resistance of the weld 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 the contact surface of the two plastics quickly melted, plus a certain pressure, so that it fused into one. When the ultrasonic stop acting, so that the pressure continues, there is a little holding time, so that the solidification of the shape, so that the formation of a solid molecular chain, to achieve the purpose of welding, welding strength can be close to the strength of the raw material body.
