Principle of Ultrasonic Welding
Principle of Ultrasonic Welding – Ultrasonic Sewing Machine – Cheersonic
Ultrasonic welding uses high-frequency vibration waves to be transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects are rubbed against each other to form a fusion between molecular layers.
The main components of an ultrasonic welding system include:
Ultrasonic generator/transducer/horn/welding head triple group/mold and frame.
Ultrasonic welding uses an ultrasonic generator to convert 50/60Hz current into 15, 20, 30 or 40 KHz electrical energy. The converted high-frequency electric energy is again converted into mechanical motion of the same frequency through the transducer, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The welding head transfers the received vibration energy to the joint of the workpiece to be welded. In this area, the vibration energy is converted into heat energy by friction to melt the area of the part that needs to be welded. Ultrasound can be used not only to weld metals and hard thermoplastics, but also to process fabrics and films. This article mainly introduces fabric welding.
The performance required by modern ultrasonic textile sewing machines: flexibility and easy operation. The new USM550S uses high-tech components to achieve a high level of precision work. The multi-functional and humanized design achieves high productivity and repeatability.
The new generation of ultrasonic textile sewing machines has set a new standard in the field of welding products. This includes easy-to-operate software that can be easily used by both beginners and experienced professionals.
The newly developed ultrasonic control system can ensure accurate and constant amplitude value, especially in the case of high speed and sensitive materials.
