Key Features of Square Tube Roll Forming Machine

1.Dual forming modes—Direct Square Forming and Round-to-Square—allow one mill to produce both square and rectangular tubes. Wide size range with shared tooling greatly reduces changeover costs.

2.Precision rollers and rigid stands ensure consistent tolerances within ±0.10mm on width and diagonal. Naturally rounded corners eliminate collapse and waviness, delivering a scratch-free surface.

3.Equipped with high-power solid-state HF welder and closed-loop squeeze control, welding speeds reach 100 m/min. The narrow heat-affected zone ensures a weld stronger than the parent metal, with automatic ID/OD scarfing.

4.CNC auto-adjustment system repositions roll stands automatically by simply inputting the side length and wall thickness on the touchscreen. Size changeover time drops from 2 hours to just 15 minutes, perfect for small-batch, multi-size orders.

5.PLC-based centralized control with a ±1.0mm precision CNC flying saw. Supports remote maintenance and real-time data monitoring, enabling fully automated, unattended operation from decoiling to finished tube.
