8-20 m/min High-Speed Door Frame Roll Forming Machine with 7.8 kW Motor and 1.0-1.2mm Capacity Steel Door Frame Forming Machine

Manufactured by Howann, the Steel Door Frame Roll Forming Machine is engineered to meet the rigorous tolerances and high-volume production schedules demanded by modern commercial and residential construction hardware suppliers. Whether fabricating heavy-duty security door frames, fire-rated metal door jambs, or rolling shutter guide tracks, this automated production line delivers consistent, high-speed profile forming with minimal manual intervention.

Constructed upon a heavy-gauge 350H welded steel structural base that absorbs torsional vibration during high-speed runs, the Howann profiling station integrates quenched and tempered 45# steel rollers, precision-hardened Cr12 alloy cutting blades, and a programmable PLC touch-screen control panel. Designed to handle standardized steel coils, the machine achieves a continuous forming velocity of 8 to 20 meters per minute while maintaining strict profile symmetry.

• Rapid 8–20 m/min Production Speed: Optimized gear-and-motor drive system delivers swift, continuous forming output to fulfill large manufacturing batch orders efficiently.
• Rigid 350H Steel Base Chassis: Heavy structural steel framework provides exceptional rigidity, preventing structural flexing under high torsional loads.
• Precision Cr12 Hydraulic Shearing: Heat-treated Cr12 mold steel cutting blades shear formed profiles instantly without burrs, distortion, or material waste.
• Intelligent PLC Touchscreen Interface: Programmable length counting and batch management allow operators to switch between automatic and manual modes with ease.
• Durable 45# Quenched Rollers: Precision-machined forming rolls undergo rigorous thermal quenching and tempering to ensure long-term wear resistance.

1. Coil Entry & Guidance: Flat metal strips are fed smoothly into the adjustable round-wheel feeding table with minimal alignment error.
2. Multi-Stage Roll Forming: Progressive forming stations gradually bend the steel strip through precise passes, transforming flat metal into rigid door frame profiles.
3. Automated Length Measurement: Rotary encoders track linear movement, signaling the PLC controller when the target door frame length is reached.
4. Hydraulic Guillotine Cutoff: The automated hydraulic cutting system shears the profile cleanly to exact dimensions, ready for welding and assembly.
