| The principle of ultrasonic plastic welding is that a generator produces a 20kHz (or 15kHz) high-voltage, high-frequency signal, which is converted into high-frequency mechanical vibration by a transducer system. This vibration is applied to the plastic workpiece, and the friction between the workpiece surface and molecules raises the temperature at the interface. When the temperature reaches the workpiece’s melting point, the interface melts rapidly and fills the gaps. When the vibration stops, the workpiece cools and solidifies under pressure, thus achieving the weld. New types of ultrasonic plastic welding machines are particularly effective for welding softer materials like PE and PP, as well as extra-large diameter and extra-long plastic parts, meeting the needs of various products. |
