High-Precision Automated Round Duct Machines

HYRUN Technology's Round Duct Machines transform coiled steel strip into precise spiral ductwork through an automated, continuous process:

• Material Feeding: Coiled metal strip is automatically fed into the machine.

• Spiral Forming: The strip is shaped into a continuous spiral profile with controlled overlap.

• Lock Seam Forming: Edges are interlocked and rolled into a strong, airtight helical seam.

• Automatic Cutting: The formed spiral duct is cleanly cut to preset lengths.

• Output: Finished, rigid round ducts exit the machine ready for installation.

HYRUN machines deliver high efficiency, consistent quality, and exceptional seam integrity for reliable HVAC duct systems.

• Material Feeding & Flattening: Coiled steel strip is automatically fed through precision leveling rollers, ensuring flawlessly flat material for consistent forming.

• Roller-Based Rounding: The strip passes through multi-stage forming stations, progressively bending it into a perfect circular profile with controlled curvature.

• Seam Interlocking: Dual servo-powered rollers mechanically interlock longitudinal edges into a rigid, airtight helical seam without adhesives.

• Servo-Driven Cutting: Programmable flying shears cleanly cut ducts to preset lengths (±1mm accuracy) without stopping production flow.

• Automated Ejection: Finished ducts transfer via conveyor to stacking stations, ready for flange installation.
