• 28khz/200W Small Size Ultrasonic Transducer For Plastic Spot Welding Machine Emitter The precept of ultrasonic welding transducer has similarities to that of cleaning transducer. It additionally achieves high-frequency vibration with wide amplitude by means of means of applying prestress to offset the expansion strain of piezoelectric ceramics. Because the welding transducer requires large instant power, it has excessive requirements for supplies and technology. It is a high-power acoustic super energy device. Usually, it cooperates with the horn and working head to kind a high-power and large amplitude vibration components to complete the ultrasonic welding of plastics, metals and assorted materials welding is to generate high-frequency friction and heat at the contact hole surface of the welded object under pressure within the course of the ultrasonic vibration generated by way of the transducer, as a manner to acquire the point of thermal fusion welding. Ultrasonic welding transducer is a high-power transducer with gap or pulse operation. Its strength is often calculated by means of instant top power. Precautions for set up of ultrasonic transducer :1. Select correct materials and modify hardness exercise to assignment and bring horn and dealing head. When putting in the horn or working head, ensure you pay attention in on frequency matching, and keep on with sound guide glue on the joint. Clean the joined floor with acetone and other solvents all the way through installation4. The impedance leadership process of the bonding task is established to play down the bonding impedance of the vibrator and upgrade the electroacoustic conversion performance of the vibrator. Pay consideration to recuperating the insulation measures after the set up of vibrator electrode.
