    Why 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.

    Unmatched Production Efficiency & Labor Savings

    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.

    High-Grade Materials & Long Service Life

    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.

    Frequently Asked Questions

    Why are TDC flanges preferred for large ductwork?

    TDC flanges provide superior strength and structural integrity over TDF flanges, making them ideal for large-section and high-pressure ductwork systems.

    How does the LIDING flange machine prevent air leakage?

    The precision-formed flange profile ensures a tight fit when assembled with corner pieces and gaskets. An optional automatic sealing mastic injector can also be integrated to further improve airtightness and lower system energy loss.

    What quality assurance tests are completed before shipment?

    Every machine undergoes a full load run, flange profile inspection, dimensional verification, and cutting accuracy validation at the factory before it is shipped.

    What are the speed and control options for the LIDING flange machine?

    The standard production speed is 6-8 m/min, which can be upgraded to 10-14 m/min. The machine features a standard Panasonic PLC (with an optional Siemens PLC) and offers cutting options such as a pneumatic circular saw or a high-precision servo flying cut.

    What is the standard production sequence for the TDC flange?

    The process sequence is: 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.

    What support is included under the LIDING warranty?

    LIDING provides a 12-month warranty with free replacement parts shipping, complete technical documentation for self-installation, and lifetime online technical support via WeChat, WhatsApp, or video conference.
