car door panel ultrasonic plastic welding machine

Car Door Panel Plastic Welding Machinery is a high-performance ultrasonic system engineered for automotive door panel welding and assembly applications. With a powerful 35 kW output and advanced ultrasonic technology operating at 20 / 35 / 40 kHz, this machine ensures strong, seamless, and distortion-free joints for large plastic components.
It is designed to weld materials like PP, HDPE, PE, PVC, and EVA with superior precision and consistency. Using ultrasonic vibrations, the machine generates frictional heat at the joint interface, enabling a permanent molecular bond without the need for adhesives, screws, or solvents.
Built for high-volume production lines, this system features double-track automatic operation, multi-point welding capability, and digital tuning control for accurate parameter adjustment and efficient workflow. It’s widely used in automotive manufacturing for welding interior and exterior components such as door panels, wheel covers, dashboards, and bumpers.
