Product Description

Ultrasonic welding converts a 50/60 Hz current into 15, 20, 30 or 40 KHz of electrical energy through an ultrasonic generator. The converted high frequency electrical energy is again converted by the transducer into a mechanical motion of the same frequency, and then the mechanical motion is transmitted to the welding head through a set of horn devices that can change the amplitude. The horn transfers the received vibrational energy to the joint of the workpiece to be welded, in which the vibrational energy is converted into thermal energy by friction to melt the plastic. Ultrasound can be used not only to weld hard thermoplastics, but also to fabrics and films.

Welding advantages
1. Ultrasonic plastic welding advantages: fast welding speed, high welding strength and good sealing;
It replaces the traditional welding/bonding process, is low in cost, clean and pollution-free and does not damage the workpiece;
The welding process is stable and all welding parameters can be tracked and monitored by the software system. Once the fault is found, it is easy to eliminate and maintain.
2, ultrasonic metal welding advantages: 1), welding materials do not melt, not fragile metal properties. 2), good electrical conductivity after welding, the resistance coefficient is extremely low or nearly zero. 3), the welding metal surface requirements are low, oxidation or plating can be welded. 4), welding time is short, no need for any flux, gas, solder. 5), welding without sparks, environmental protection and safety.

The special ultrasonic mechanism for the mask machine is mainly used for welding the ear band or the welding edge of the mask machine, the frequency is 15-20K, the power is 2KW or 2600W, and the steel mold can be customized according to the requirements of the mask machine. The welding is firm and beautiful and fast. Ultrasonic models use computers to automatically track the frequency. Before working, please carefully check whether the mold and transducer frequency are within the automatic tracking frequency range of this model. If the frequency is out of range, the machine will experience frequency lockout protection.

The principle of ultrasonic mask machine welding mainly uses ultrasonic technology to transmit ultrasonic energy to the welding area through the upper weldment. Because the welding area, that is, the acoustic resistance at the interface of two weldings, will generate local high temperature. In addition, due to the poor thermal conductivity of plastic, nylon, chemical fiber, non-woven fabric, multi-layer fabric, gold cloth and other materials, they cannot be distributed in time for a while and gather in the welding area, causing the two contact surfaces to melt rapidly. After a certain pressure, it Fusion into one. When the ultrasonic stops, let the pressure continue for a while to hold the pressure to make it solidify and shape, thus forming a solid molecular chain, to achieve the purpose of welding, the welding strength can be close to the strength of the raw material, which is what many manufacturers need to use The reason why NVC ultrasonic mask production and welding is fast, clean, safe, stable, and high-yield. It also makes the wearer's ears comfortable and stress-free. The mask filter cloth layer has a good filtering effect, which perfectly fits the Asian face. It is extremely suitable for the current epidemic personal protective masks, high-polluting red zone protective masks, and can be applied to high-pollution industries such as construction and mining.
