Ultrasonic transducers are used in conjunction with ultrasonic plastic welding machines to weld plastic products. Ultrasonic plastic welding machines have different welding sizes due to different use occasions and welding materials, and their specifications are also various.Its output power is from manual welding.Tool heads, with and without amplitude amplification, are used for acoustic system tool heads for plastic welding machines. The material used is usually aluminum alloy, and the end surface is plated with cemented carbide. When the power is high, it can also be made of titanium alloy.As a result, the fatigue strength of the material is more than twice that of aluminum alloy.
