TDF Flange Forming Machine for HVAC Rectangular Air Duct
Dual-Station Flange & Hook Connector Forming: Features dedicated dual roll-forming stations—one side rolls integral TDF duct flanges, while the opposite side forms matching hook-type flange connectors (clips) without changing tooling.
High Working Capacity (T-12 & T-15): Available in T-12 (0.5–1.2 mm / 18 Ga galvanized steel) and heavy-duty T-15 (0.8–1.5 mm / 16 Ga galvanized steel or up to 1.2 mm / 20 Ga stainless steel plate).
Industrial Hardened Tooling: Built with GCr15 vacuum-quenched forming rollers, thermal-refined 40Cr roller shafts, vacuum-quenched 20CrMoT gears, and authentic Harbin (HRB) precision ball bearings.
Fast & Reliable Workshop Output: Operating speed of 9 m/min (26 ft/min) driven by a 3–4 kW Nanjing Volp motor; arc-welded rigid steel frame with universal voltage support (220V/380V/450V).
Overview & TDF Duct Flange Forming
The TDF Flange Forming Machine (TDF Roll Former) is a foundational, cost-effective sheet metal profiling solution for modern rectangular air duct manufacturing. It rolls integral common-plate flanges directly onto the perimeter of duct panels, eliminating separate angle-iron frames and speeding up on-site ventilation installation.
Equipped with dual-side rolling stations, this machine forms practical, aesthetic, and airtight flange joints while dramatically reducing metal fabrication labor and raw material consumption.
Dual-Side Workstations & Core Functions
The machine incorporates two functional roll-forming stations operating independently on either side:
- TDF Flange Station (Primary Side): Forms continuous, clean TDF common-plate flange profiles directly on the edge of rectangular duct sheets.
- Hook Connector Station (Secondary Side): Dedicated to rolling “hook-type” flange clips (cleats) used to join adjacent duct sections together firmly.
- Quick-Clamping Infeed Guides: Equipped with quick-release levers and precision side rollers to ensure straight sheet feeding and uniform flange profiles.
