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

Manufactured by Howann, the Steel Door Frame Roll Forming Machine is engineered to meet the stringent structural tolerances, heavy load-bearing requirements, 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# forged steel rollers, precision-hardened Cr12 mold steel cutting blades, and a programmable PLC touch-screen control panel. Designed to handle standardized metal strips, the machine achieves a continuous forming velocity of 8 to 20 meters per minute while maintaining strict profile squareness and surface integrity.

• Firsthand Manufacturing Experience: Field-tested and refined for continuous industrial operation, producing flat, wrinkle-free door jamb profiles that meet international building safety codes.
• Rigid 350H Steel Base Chassis: Heavy structural steel framework provides exceptional torsional rigidity, preventing structural flexing under high-speed multi-stage forming loads.
• Precision Cr12 Hydraulic Shearing: Heat-treated Cr12 mold steel cutting blades shear formed profiles instantly without burrs, distortion, or damage to the galvanized coating.
• Intelligent PLC Touchscreen Interface: Programmable length counting, automated batch management, and inverter control allow operators to switch between custom cutting lengths seamlessly.
• Durable 45# Quenched Rollers: Precision-machined forming rolls undergo rigorous thermal quenching and tempering to ensure long-term wear resistance and protect zinc layers.

• Coil Loading & Entry: Galvanized or cold-rolled metal coils are uncoiled and fed smoothly into the adjustable guiding table with minimal alignment error.
• Multi-Stage Progressive Forming: Progressive forming stations gradually bend the steel strip through precise passes, transforming flat metal into rigid door frame profiles.
• Automated Length Measurement: Rotary encoders track linear movement, signaling the PLC controller when the target door frame length is reached.
• Hydraulic Guillotine Cutoff: The automated hydraulic cutting system shears the profile cleanly to exact dimensions, ready for welding, assembly, and hardware installation.

• Security Door Manufacturing: Fabricating robust steel door frames and reinforced jambs for residential and commercial buildings.
• Fire-Rated Door Assembly: Producing certified hollow metal door profiles meeting strict life-safety building regulations.
• Industrial Rolling Shutters: Manufacturing interlocking guide channels and curtain slat profiles for warehouse security doors.

• Comprehensive Warranty Protection: Backed by a 1.5-year free warranty covering motors, gearboxes, and PLC logic modules, with replacement parts dispatched promptly.
• Transparent Quality Assurance: Every machine undergoes rigorous pre-shipment outgoing inspections, complete with video testing reports and operational sign-offs.
• Global Technical Guidance: Supported by dedicated Howann engineers providing lifetime online technical support and detailed video installation manuals.
