• 28KHz/100Watt Small Size Low Frequency Piezoelectric Transducers For Handheld Plastic Welder Portable Spot Welding Machine The precept of ultrasonic welding transducer is similar to that of cleansing transducer. It also achieves high-frequency vibration with huge amplitude by means of making use of prestress to offset the growth pressure of piezoelectric ceramics. Because the welding transducer requires great immediate power, it has immoderate standards for supplies and technology. It is a high-power acoustic super energy device. Usually, it cooperates with the horn and working head to variety a high-power and big amplitude vibration formulas to complete the ultrasonic welding of plastics, metals and assorted materials welding is to generate high-frequency friction and heat on the touch gap surface of the welded object stressed through the ultrasonic vibration generated through the transducer, to be able to obtain the point of thermal fusion welding. Ultrasonic welding transducer is a high-power transducer with gap or pulse operation. Its energy is always calculated through immediate peak power. Precautions for installation of ultrasonic transducer :1. Select appropriate materials and alter hardness assignment to activity and bring horn and working head. When putting in the horn or working head, ensure you pay attention to frequency matching, and practice sound instruction manual glue on the joint. Clean the joined surface with acetone and assorted solvents all through installation4. The impedance control technique of the bonding task is established to lessen the bonding impedance of the vibrator and upgrade the electroacoustic conversion functionality of the vibrator. Pay attention to getting better the insulation measures after the set up of vibrator electrode.
