Ultrasonic Welding for N95
Ultrasonic welding is the conversion of a 50/60Hz current into 15, 20, 30 or 40 KHz electrical energy through an ultrasonic generator.
The converted high-frequency electrical energy is converted through the transducer again into mechanical motion of the same frequency, which is then transmitted to the welding head through a set of lubber devices that can change the amplitude.
The welding head transfers the received vibration energy to the joint of the part to be welded, where the vibration energy is converted into heat energy by friction, melting the plastic.
Ultrasound can be used not only to weld hard thermoplastics, but also to process fabrics and films.
The main components of an ultrasonic welding system include an ultrasonic generator, a transducer welding head and flange.
