الوصف

The equipment transmits high-frequency vibration waves to two or more surfaces of materials to be welded. Under pressure, the surfaces of materials rub and heat each other to form the fusion between molecular layers, so as to achieve the fusion of materials such as cloth and cloth, cloth and chemical fiber cotton, plastic film and plastic film, fabric and glue spraying cotton, non-woven fabric, sponge and other materials, thus completing the welding. Its advantages are fast, energy-saving, high fusion strength, good conductivity, non sparking, and close to cold processing
