800W Auto Ultrasonic Riveting for Welding Car Bumper
Principle of Ultrasonic Car Bumper Riveting Spot Welder:
When the ultrasonic role in the thermoplastic plastic contact surface, it will generate tens of thousands of times per second, high frequency vibration, this high-frequency vibration, ultrasonic energy through the ultrasonic wave transmitted to the mold to ultrasonic welding material surface, it will produce high-temperature materials. Plastic contact surface resulting in rapid melting, coupled with stress, it blend and coagulation, so that to achieve the purpose of ultrasonic welding.
What is the welding principle of ultrasonic plastic welding machine?
The machine converts electrical energy through ultrasonic transducers into ultrasonic energy (ie, high-frequency mechanical vibration energy whose frequency exceeds the auditory threshold of the human ear). This energy is transmitted through the welding head to the plastic workpiece at an ultrasonic frequency of tens of thousands of times per second and at a certain level. The amplitude of the plastic workpiece joint friction and then melted. The brief pressure maintained on the workpiece after the vibration is stopped causes the two weldments to solidify as a molecular link. The general welding time is less than 1 second, the obtained welding strength can be comparable with the body.
