1. The principle of pneumatic propulsion is used to push the aluminum nose bridge strip with hot melt backing adhesive. After heating, the surface adhesive melts and is bonded to the periphery of the mask nose bridge by gas propulsion. The bonding strength is firm and the welding and shaping effect is good.

2. It includes the function of hot pressing reinforced back adhesive sponge inner nose bridge strip; Paste more firmly and have better air tightness.

3. Imported cylinder, precision processed copper press mold, adjustable hot pressing temperature and pressing time, one-time welding and shaping completed without damaging the surface of the mask.

4. The structural design is compact and beautiful, and easy to install and debug. Foot pedal control, simple operation, high production efficiency.
