Principle: Ultrasonic spot welding machine uses high-frequency vibration waves to transmit them to the surfaces of two objects to be welded. Under intense pressure, the surfaces of the two objects rub against each other, and the molecular layers form a tight fusion. Efficient ultrasonic welding: only needs 0.4-8s per welding time, with fast welding speed and high efficiency, which can easily help you complete the welding work. (1200W) High quality: The spot welding is carefully made of stainless steel, is corrosion resistant, wear-resistant, not easy to deform and durable. The greater the performance of the machine, the faster the welding speed is and the stronger the welding. Reduce Cost: Ultrasonic non-woven spot welder does not require screws or glue during the welding process. This machine completes the connection work through ultrasonic vibration, which can reduce labor and material costs and bring you high income. Application: It is suitable for welding, riveting and spot welding of non-woven fabrics, thermoplastics, nylon fabrics, etc.
