My company (Wu Xia 152 516 468 934) introduced a full set of filter bags welding equipment - Ultrasonic lace machine sealing, hot air welding instead of sewing cloth in sealed, ultrasonic welding pocket with PP ring connection and sealing the tail instead of the original sewing. Well received by the industry's favor, we are committed to Nicole will be the best equipment, best service, the fastest pace of innovation to return all customers. 

 Ultrasonic welding is a welding thermoplastic products, high technology, a variety of thermoplastic plastic parts can be used for ultrasonic welding process, without additional solvents, adhesives or other supplements. The advantage is increased many-fold productivity, reduce costs, improve product quality and safety. 

 Ultrasonic plastic vibration, added to plastic parts, through the surface and internal molecular friction, sent to the interface temperature, when the temperature reaches the melting point of this piece itself, so that the rapid melting of workpiece interface, and then fill in the interface the gap between when the vibration stops, the workpiece under pressure while cooling in certain amorphous, they achieve perfect welding results. Principle by welding generator 20KHZ (or 15KHZ) high-pressure, high-frequency signal, through the change.
