800W Auto Ultrasonic Riveting for Welding Car Bumper
Ultrasonic characteristics and application
1) Ultrasonic waves can be effectively propagated in media such as gases, liquids, solids, and solid solutions.
2) Ultrasonic waves can transmit very strong energy.
3) Ultrasound produces reflection, interference, superposition and resonance.
4) When ultrasonic waves propagate in a liquid medium, strong impact and cavitation can occur at the interface.
What are the advantages of ultrasonic plastic welding compared to conventional welding?
Different with the traditional plastic welding methods, ultrasonic plastic welding usually does not need to be filled with any filler. It is a qualitative leap in plastic welding and has been used in many industrial sectors, especially for some large or complex plastic parts, such as Injection molded parts such as high-end automobile instrument panels and automobile bumpers can be decomposed into a plurality of small sections that are easy to manufacture, and then ultrasonically welded to connect them with almost no trace of welding, thereby solving the large injection. The difficulty in manufacturing molds and molding machines has reduced costs, and this method has also begun to be used in the automotive industry and has highlighted its superiority.
