28khz 1200W Portable Ultrasonic Plastic Welder Spot Welding Machine For Strap Velcro

Introduction to the Functions of Handheld Ultrasonic Spot Welder Ultrasonic Overview Ultrasonic is not only very useful in welding, but also widely used in other industries, such as ultrasonic cleaning. Ultrasonic welding is the use of high-frequency vibration waves to transmit to the surfaces of two objects that need to be welded. Under pressure, the surfaces of the two objects rub against each other to form fusion between molecular layers. Ultrasonic cleaning utilizes the cavitation, acceleration, and direct inflow effects of ultrasound in liquids to directly or indirectly disperse, emulsify, and peel off the dirt layer, achieving the cleaning purpose. In ultrasonic cleaning machines, cavitation and direct inflow effects are more commonly used.
