Ultrasonic mask welding equipment

Welding principle of ultrasonic mask machine：

Using ultrasonic technology, ultrasonic energy is transmitted to the welding area through the upper welding piece. Due to the high acoustic resistance at the interface between the two welds, local high temperatures are generated in the welding area. Due to the poor thermal conductivity of materials such as plastic, nylon, synthetic fibers, non-woven fabrics, multi-layer fabrics, and gold fabrics, heat cannot be dissipated in a timely manner and accumulates in the welding area, causing the two contact surfaces to quickly melt. After applying a certain pressure, they fuse into one.
