With the spread of the global epidemic, many countries lack of anti epidemic materials such as masks. The supply and demand of masks are still tight, and the shortage is still huge.

It is inevitable to continue to provide guarantee for mask production capacity and provide sufficient epidemic prevention materials!

In order to meet the production needs of different customers' masks, Supersonic launched the table type ultrasonic band spot welding machine.

Supersonic ear band spot welding machine.

Ultrasonic welding is an essential process for mask production. The ultrasonic table type ear belt spot welding machine is designed for spot welding of mask ear belt, which is suitable for the welding of all kinds of mask ear belt. It can eliminate the complicated process of traditional operation such as sewing and gluing. It is simple, stable, environmental friendly and efficient. It is the best supplement of automatic ear belt welding equipment.

Welding principle

1. When ultrasonic wave acts on the contact surface of thermoplastic, it will produce tens of thousands of high frequency vibrations per second.

2. The high frequency vibration transmits the ultrasonic energy to the welding area through the upper weldment. The interface of the two weldments has a large acoustic resistance, so the local high temperature is produced.

3. The thermal conductivity of plastic is poor. The heat is gathered in the welding area. The contact surface of two plastics melts rapidly. With a certain pressure, they can be integrated into one.

4. After the ultrasonic stop, let the pressure last for a few moment, make it solidify and form a solid molecular chain to realize welding. The welding strength is close to the strength of the raw material itself, and the pressing part is firm and does not deform.
