Coorig round duct fabrication equipment
Coorig YFL-40 CNC Round Flange Forming Machine is built for HVAC duct workshops that need formed flange rings for spiral ducts, round air ducts, and fan duct assemblies. It turns steel strips into angle iron profiles with rolling and cutting functions, helping production teams keep round duct connection parts more consistent across repeated project batches.
For an overseas buyer comparing a ducting machine supplier, the important review points are material thickness, bending diameter, flange width combinations, CNC control, electrical component list, and how the equipment fits beside spiral duct forming, punching, spot welding, and assembly stations.
Factories reviewing ducting and forming machines can use this page to connect the YFL-40 specification data with application planning for round duct production, ventilation projects, and mid-volume HVAC component supply.
Review the machine view beside the core production parameters to confirm whether the YFL-40 fits the planned round duct diameter range, steel strip thickness, and workshop process flow.
The YFL-40 machine forms steel strips into angle iron profiles used for spiral duct flanges, round air duct connections, and fan duct parts. Its practical value is strongest where a factory needs adjustable flange widths, stable bending across several duct diameters, and a CNC-controlled process that can reduce manual marking, rolling, and cutting variation during repeat production.

5/5 Rating
"Our duct shop needed a clearer way to compare flange width, diameter range, and machine footprint. The YFL-40 specification made it easier for engineering and purchasing to review the same data."

These technical questions help procurement teams prepare drawings, workshop data, and production requirements before discussing the YFL-40 machine with Coorig.
The YFL-40 CNC Round Flange Forming Machine is used for forming steel strips into angle iron profiles for spiral duct flanges, round air duct joints, and fan duct components. It suits workshops that need repeatable flange geometry across duct diameters instead of relying on manual forming and cutting steps.
The listed processing thickness range is 1.5-4 mm. Buyers should share the common steel grade, strip thickness, target flange size, and finished duct diameter so the supplier can check tooling match, feeding stability, and the practical setup for the planned production mix.
The machine lists a bending diameter range of 230-1800 mm, which helps workshops cover compact round duct parts and larger ventilation or fan duct assemblies. Procurement teams should compare that range with project drawings, duct standards, and the expected split between small and large diameter production.
The product page lists a Kuntai Tongtai monitor, Panasonic Japan PLC, Schneider Electric AC contactor, Schneider Electric relay, Taiwan Mingwei power supply, 5.5 kW brake motor reducer, 4 kW copper oil pump motor, and Beijing Huade relief valve. These details help engineers review the control cabinet and maintenance expectations before ordering.
Useful information includes available floor space, power supply, material storage method, strip feeding direction, operator access, finished part handling, and whether the machine will stand near a spiral duct forming line, punching station, spot welding station, or separate assembly area.
Sample review should compare flange width, angle consistency, rolling marks, cut quality, circular fit, joint alignment, and repeatability across several diameters. A practical evaluation also checks whether feeding speed and setup changes can be controlled without excessive trial material.
