lidingWhy do professionals choose LIDING flange machines?
Heavy-Duty Frame – High Flange Strength for Large Ducts
-
TDC flanges provide superior strength over TDF for large-section and high-pressure ductwork. This machine features 18 or 24 precision roller stations with an optional high-rigidity gearbox drive for enhanced stability. Roller material options include GCr15 or Cr12MOV, precision-machined and heat-treated for accurate profile dimensions. Backed by over 30 years of cold roll forming expertise, Liding machines serve customers in more than 50 countries worldwide.
-
Precision Forming with Low Air Leakage
-
The precision-formed flange profile ensures tight fit when assembled with corner pieces and gaskets, minimizing air leakage and reducing system energy loss. An optional automatic sealing mastic injector further enhances airtightness. The optimized number of roller stations distributes forming forces evenly, ensuring smooth operation and consistent product quality. Machine noise level ≤82dB(A) meets workshop environmental standards. CE certified for international export.
-
12-Month Warranty + Factory Pre-Testing
-
Every machine undergoes full load run, flange inspection, dimensional verification, and cutting accuracy validation before shipment. Complete technical documentation (installation drawings, circuit diagrams, manuals, video tutorials) is provided for self-installation. On-site engineer support available at additional cost. 12-month warranty with free replacement parts shipping. Lifetime online technical support via WeChat/WhatsApp/video conference.
-
Efficient Production with Flexible Configuration
-
Standard speed 6-8 m/min, upgradeable to 10-14 m/min. Panasonic PLC standard, Siemens PLC optional. Cutting options include pneumatic circular saw (non-stop) or servo flying cut for higher precision. Gearbox drive option replaces standard chain drive for smoother operation and reduced maintenance. 85% customer repurchase rate confirms long-term reliability.
-
Standard Production Process
-
Steel coil → Uncoiling → Roll forming (18/24 stations) → Precision cutting → Finished TDC flange profile → Inserted into duct ends + Corner pieces + Clamps → Completed TDC flange connection
