At present, the demand for masks is increasing, what is the role of ultrasonic welding system in the manufacturing process of masks? That is the application of ultrasonic welding technology. We can see some indentation on the mask, such as the ear band, the mask sealing edge, and the N95 mask exhalation valve, which are all using ultrasonic welding technology.
Ultrasonic Welding principle:
Ultrasonic welding convert 50 or 60 hz current into 15, 20, 30 or 40 khz electrical energy through ultrasonic generators, transducers and piezoelectric transducers. The converted high frequency electrical energy is converted by a transducer into mechanical motion of the same frequency, Then the mechanical motion is transmitted to the welding horn through a set of adjustable amplitudes. The welding horn transmits the received vibration energy to the joint of the workpiece to be welded, where the vibration energy is converted into heat energy by friction to melt the plastic. Ultrasonic waves can be used not only to weld hard thermoplastics, but also to process fabrics and films.
The following is the common application of ultrasound in masks
Ultrasonic Mask seal edge machine: also known as mask sealing machine, mask edge pressing machine. this machine adopts ultrasonic mask welding system, equipped with the corresponding ultrasonic mold. this machine is used for all kinds of mask edge pressing, mask edge sealing, non-woven cloth sealing, KN95 mask equipment, N95 mask, children’s mask, PM2.5 protective mask, industrial mask, etc.
Mask ear loop welding machine: this machine adopts ultrasonic mask welding system, equipped with the corresponding ultrasonic mold, this machine is used for all kinds of mask ear loop welding, KN95 mask equipment, N95 mask, children’s mask, PM2.5 protective mask, industrial mask, etc.
