Ultrasonic tool head of plastic ultrasonic welding machine

There are two kinds of tool heads with amplitude amplification and without amplitude amplification. The tool head of acoustic system for plastic welding machine is usually made of aluminum alloy, and its end face is plated with cemented carbide. When the power is large, it is also made of titanium alloy, and the fatigue strength of this material is more than twice that of aluminum alloy. Different tool heads are required for different welding objects. Whether it is near-field welding or transmission welding, only half wavelength tool head can make the welding end face reach the maximum amplitude.
