This prompts automobile manufacturers to seek more advanced, efficient and diversified design requirements for interior panel connection technology. Ultrasonic welding generates heat by high-frequency vibration between the surface molecules of the interior panel material to be welded, thereby realizing rapid fusion connection. Its welding speed is fast, and the welding process can be completed in a short time, greatly improving the production efficiency of the automobile interior.
