• 28KHz 200W Piezoelectric Ultrasonic Transducer For Ultrasonic Plastic Welding Machine The principle of ultrasonic welding transducer is similar to that of cleansing transducer. It additionally achieves high-frequency vibration with huge amplitude through way of making use of prestress to offset the expansion pressure of piezoelectric ceramics. Because the welding transducer demands great instant power, it has high standards for supplies and technology. It is a high-power acoustic great energy device. Usually, it cooperates with the horn and dealing head to form a high-power and big amplitude vibration approach to complete the ultrasonic welding of plastics, metals and other materials welding is to generate high-frequency friction and heat at the contact gap surface of the welded object under pressure throughout the ultrasonic vibration generated by way of technique of the transducer, with the purpose 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 by means of approach of prompt height power. Precautions for set up of ultrasonic transducer :1. Select right supplies and change hardness process to activity and convey horn and working head. When installing the horn or operating head, make sure you hear in on frequency matching, and prepare sound guide glue at the joint. Clean the joined floor with acetone and other solvents all the way through installation4. The impedance leadership strategy of the bonding process is established to reduce the bonding impedance of the vibrator and improve the electroacoustic conversion performance of the vibrator. Pay consideration to recuperating the insulation measures after the installation of vibrator electrode.
