Precision Manufacturing Capabilities
High-Precision Multi-Pass Roll Forming System
The mill adopts advanced multi-pass roll forming technology with optimized roll design to gradually shape stainless steel strips into precise tubular profiles. Precision-machined alloy steel rolls ensure stable forming, excellent tube roundness, smooth surface quality, and accurate dimensional control. Quick-change tooling options help reduce setup time and improve production efficiency.
Advanced Welding & Seam Treatment Integration
Equipped with TIG or fiber laser welding systems, the production line provides strong weld penetration, narrow heat-affected zones, and excellent corrosion resistance. Optional seam treatment processes, including bead rolling, seam grinding, and bright annealing, ensure smooth weld quality and consistent tube performance.
Precision Sizing and Straightening Unit
Multi-stage sizing and straightening systems effectively eliminate welding deformation and residual stress. Advanced measuring devices monitor tube diameter, ovality, and straightness in real time to maintain high precision and meet strict industrial standards.
Intelligent Automation and Motion Control
The complete line integrates PLC control, touchscreen HMI, automatic parameter management, and intelligent monitoring systems. Functions such as synchronized drive control, automatic cutting, length measurement, and tube collection improve production stability, efficiency, and material utilization.
