Fully Automatic Stainless Steel Square Tube Making Machine

Fully Automatic Production Integration
The line seamlessly integrates automatic coil feeding, precise strip leveling, multi-stage roll forming, high-frequency welding, sizing, straightening, and automatic length cutting. This high degree of automation reduces labor intensity, minimizes human error, and guarantees consistent output during 24/7 continuous industrial operations.

High-Precision Roll Forming Technology
Utilizing advanced computer-optimized roll pass designs and high-rigidity machine stands, the forming section ensures smooth metal flow and accurate corner radii. This minimizes stress marks, prevents material scratching, and maintains superior straightness and tight tolerances across all production runs.

Superior Stainless Steel Welding Performance
Equipped with state-of-the-art high-frequency welding units and precise thermal monitoring, the system creates uniform, robust weld seams with minimal burrs. The optimized heat-affected zone protects the corrosion resistance of the stainless steel, making it ideal for high-end decorative and structural applications.

Stable and Efficient Output
The combination of heavy-duty mechanical foundations, high-grade alloy steel rollers, and intelligent electrical synchronization delivers exceptional stability, lower vibration rates, and extended tool life, directly lowering overall operational costs for manufacturers.

Automatic Coil Loading & Uncoiling: The stainless steel mother coil is safely mounted and fed steadily into the accumulator.

Strip Leveling & Accumulation: The strip is flattened to remove internal stresses, ensuring smooth entry into the forming section.

Precision Roll Forming: Progressive passes through specialized rolls gradually shape the flat strip into an open square tube profile.

High-Frequency Welding: Edges are heated via induction and forged together securely by squeeze rolls.

Weld Bead Treatment & Cooling: External weld beads are trimmed smoothly, and the profile is cooled uniformly.

Sizing & Straightening: Multi-axis sizing stands correct final dimensions, angles, and straightness tolerances.

Automatic Flying Cut-Off: Computer-controlled flying saws cut the finished square tubes to exact customer lengths without stopping production.

Discharge & Packing: Finished tubes are automatically discharged, inspected, and bundled for shipment.
