HNT-8AS-6015 ( 10X4 ) Type: HNT-8AS-6015 ( 10X4) Resonance frequency ( KHz: 15 Static capacitance ( pf ) : 7800 + - 10% Resonance impedance( ) : less than 12 The ultrasonic welding transducer belongs to the high-power ultrasonic transducer. Equiped with the energy-collecting booster and work head, it can generate ultrasonic vibration, which has a high-frequency hot melting effect on the gap surface of the being pressed plastic parts, so as to achieve the purpose of welding.
