20KHZ 1500W Ultrasonic Welding Generator With Transducer For Nonwoven Fabric Mask 

The special ultrasonic mechanism of mask machine is mainly used for the welding ear band or welding edge of the mask machine. The frequency is 15-20K and the power is 2KW or 2600W. The steel mold can be customized according to the requirements of the mask machine. The welding is firm and beautiful, and the speed is fast. The ultrasonic model is a computer to automatically track the frequency. Before work, please check carefully whether the frequency of the mold and the transducer is within the frequency range automatically tracked by this model. If it is out of range, the machine will lose frequency protection.

The principle of ultrasonic mask machine welding mainly uses ultrasonic technology to transmit ultrasonic energy to the welding zone through the upper welding piece. Due to the large acoustic resistance at the welding interface, which is the interface between the two weldings, local high temperatures will occur. In addition, due to the poor thermal conductivity of plastics, nylon, chemical fibers, non-woven fabrics, multi-layered fabrics, and gold fabrics, they cannot be distributed in time and gather in the welding zone, causing the two contact surfaces to melt rapidly. After applying a certain pressure, Fusion into one. When the ultrasonic wave stops functioning, the pressure is continued, and the pressure is maintained for a while to solidify and form. This forms a strong molecular chain to achieve the purpose of welding. The welding strength can be close to the strength of the raw material. This is what many manufacturers need to use. NVC ultrasonic welding and welding masks have the advantages of fast, clean, safe, stable performance, high output, etc., and make the wearer's ears comfortable, no pressure, good filtering effect of mask filter cloth layer, and perfectly fit the face of Asians, It is very suitable for the current personal protective masks for epidemic situations, high-pollution red zone protective masks, and can be applied to high-polluting industries such as construction and mining.
