The ultrasonic welding machine using ultrasonic waves to weld thermoplastics. When the machine starts, it can raise thousands of times of high-frequency vibration. After the vibration reaches a certain amplitude per second and transmits ultrasonic energy to the welding area via the upper weldment, high temperature is generated because of the big acoustic resistances around the interface between the welding areas. Besides, because of the bad thermal conductivity of plastics, the heat energy can’t be emitted immediately, gathered in the welding area. Then the plastic surfaces fused quickly, together with a certain pressure, they are fused together.  

When the ultrasonic waves stop, the pressure maintained a few seconds to solidify it to form a solid molecular chain for welding purposes. The welding strength is equivalent to that of raw materials.                                                   Feature:                                                                           1) Intelligent frequency tracking
