How Ultrasonic Welding Works

When precision technology meets high - efficiency welding, a fascinating fusion in the microscopic world unfolds. Ultrasonic welding converts electrical energy into mechanical energy through high - frequency vibrations ranging from 15,000 to 70,000 times per second. The rapid oscillation of the welding horn causes the molecules on the contact surfaces of the materials to rub violently, instantly generating heat, like countless tiny sparks that quickly melt the material surface. At the same time, under precisely controlled pressure, the melted materials penetrate and blend with each other. After cooling, a tight and firm welded joint is formed.​

This technology requires no adhesives, is environmentally friendly, and its welding efficiency is several times that of traditional methods, significantly reducing production costs. From automotive components to smart wearable devices, from medical equipment to food packaging, ultrasonic welding has become the ideal choice for modern manufacturing, safeguarding both quality and efficiency with its excellent sealing performance and high strength.​
