20Khz Ultrasonic Replacement Converter with 4 Ceramics Golden Valve for Non Woven Welding
Dukane Converter Replacement Ultrasonic Converter 20 Khz with outcovering and connecting cable
The 20K ultrasonic converter is applied to dukane ultrasonic welding machine.
The transducer converts high-frequency electrical energy into high-frequency mechanical vibrations. And it contains several piezoelectric ceramic discs sandwiched under pressure between two metal blocks. Between each disc is a thin metal plate, which forms the electrode. When a sinusoidal electrical signal is fed to the transducer via the electrodes, the discs expand and contract, producing axial vibrations.
