In the early days, solvent or electric heating methods were used for bonding tubes. These methods had low efficiency, poor appearance, and the bonded surfaces were prone to aging, leading to an increased product defect rate and potential harm to human health. The application of ultrasonic technology has solved these problems in tube bonding.

Working principle of the ultrasonic tube sealing machine: The machine converts high-frequency electrical energy into mechanical energy through a transducer. This energy is transmitted to the tool head and then applied to the tube workpiece. At an ultrasonic frequency of 20,000 times per second with a certain amplitude, the bonding surfaces of the tube workpiece undergo intense friction, melt, and complete the bonding process in an instant. This process is called ultrasonic tube welding. The ultrasonic tube sealing and welding machine adopts electronic program control, featuring a high degree of automation and easy operation. It is equipped with a built-in electronic protection circuit.
