High Frequency 20kHz Plastic Welding Machine For Making Mask

Ultrasonic welding uses high-frequency vibration waves to transmit to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other to form a fusion between molecular layers.

High Frequency 20kHz Plastic Welding Machine For Making Mask


The 20kHz ultrasonic welding  system is currently mainly used for the production of masks. A fully automatic 1+1 plane mask machine requires three sets of 20kHz ultrasonic welding  systems, one set for the production of mask blank manking and two sets for spot welding of earloops. 


Frequency: 20kHz
