Working Principle

The P2 series ultrasonic pneumatic welding machine converts electric energy into high-frequency ultrasonic vibration energy through an intelligent ultrasonic generator. Combined with stable pneumatic pressure drive, the equipment acts on the workpiece contact surface. Relying on advanced digital frequency tracking technology, it automatically locks the optimal resonant frequency, and completes rapid molecular fusion welding within milliseconds. The four switchable intelligent welding modes realize precise control of welding time, energy and pressure, ensuring stable, accurate and high-strength welding effect for different workpieces.
