HVAC Automatic Hairpin Copper Tube Bending Machine for Long U Copper Tubes. A specialized solution that combines decoiling, straightening, chipless cutting, and bending into a single automated process, specifically designed for high-quality long U-hairpin production. Utilizes advanced chipless cutting technology to ensure clean ends and maintain maximum internal diameter (e.g., >5.6mm for 7mm tubes), preventing material waste and ensuring smooth airflow. Equipped with Mitsubishi (Japan) PLC, HMI, and Servo systems, providing ultra-stable performance, intuitive operation, and precise movement control for complex bending tasks.
