20KHz 2000W High Efficient Ultrasonic Welding Machine for Mask Making Machine

Ultrasonic Welding Solution:

SP TECH is a leading manufacturer of ultrasonic welding technology specialized in manufacturing ultrasonic welding components for face masks in china. We are capable to supply large amount of generators, converters and sonotrodes with frequency 20 kHz, 15kHz, 40 kHz, 35 kHz and 30 kHz, 28kHz.

In face masks production process ultrasonic technology is used for welding as below:

1. The edge area of mask

2. The valve / filter

3. The nose bridge of mask

4. The ear loop(ear band)
