• 28khz 200W Piezoelectric Ultrasonic Transducer For Fabric Cloth Sealing Machine Handheld Spot Welder The precept of ultrasonic welding transducer is analogous to that of cleaning transducer. It additionally achieves high-frequency vibration with extensive amplitude through applying prestress to offset the growth pressure of piezoelectric ceramics. Because the welding transducer calls for huge immediate power, it has immoderate standards for materials and technology. It is a high-power acoustic broad calories device. Usually, it cooperates with the horn and dealing head to sort a high-power and big amplitude vibration approach to end the ultrasonic welding of plastics, metals and different materials welding is to generate high-frequency friction and heat on the touch hole floor of the welded object restless during the ultrasonic vibration generated by way of the transducer, as a fashion to attain the point of thermal fusion welding. Ultrasonic welding transducer is a high-power transducer with hole or pulse operation. Its energy is usually calculated through means of immediate top power. Precautions for set up of ultrasonic transducer :1. Select appropriate materials and modify hardness assignment to job and produce horn and working head. When putting in the horn or working head, make sure you snoop on frequency matching, and practice sound guide glue at the joint. Clean the joined surface with acetone and different solvents throughout installation4. The impedance control process of the bonding assignment is established to play down the bonding impedance of the vibrator and improve the electroacoustic conversion performance of the vibrator. Pay attention to getting better the insulation measures after the set up of vibrator electrode.
