    Why do professionals choose LIDING flange machines?

    Patented mold saves you time and material

    We designed our own patented mold system—no more struggling with complicated mold changes that take half a day. Switching between different duct diameters takes just minutes, and the precision design cuts down on scrap material by up to 15%. Over a year, that adds up to real savings on your steel costs.

    Unmatched Production Efficiency & Labor Savings

    High-speed synchronous cutting that never messes up

    The integrated high-speed cutting system runs perfectly in sync with the feeding speed, so you never get crooked cuts or stuck material. It cuts clean, burr-free edges every single time, no extra sanding or trimming needed. Crank the speed up to 35m/min when you’re up against a deadline, and it’ll keep up without breaking a sweat..

    High-Grade Materials & Long Service Life

    Dead simple to operate, no pro skills required

    The intuitive touch screen PLC console makes this machine a breeze to run. A regular worker can master it in 30 minutes of training—no need to hire expensive specialized technicians. All parameters are clearly displayed, and you can save common duct sizes as presets for one-click production.

    Precise Forming Meeting International Standards

    Tough enough for the job site, not just the workshop

    Metal coil loading → Automatic feeding and guiding → Spiral roll forming → Continuous outer surface locking → High-speed synchronous fixed-length cutting → Automatic roll out → Finished spiral duct.

    Intelligent PLC Control & Easy Operation

    Standard Production Process

    Manual Coil Feeding → Automatic leveling and straightening → 10-station continuous roll forming → Hydraulic precision cutting → Finished air duct/flange discharging

    Frequently Asked Questions

    Q: How much raw material does the patented mold design save?
    The precision design of our patented mold system cuts down on scrap material by up to 15%, significantly lowering your annual steel procurement costs.
    Q: How fast can the synchronous cutting system operate?
    The cutting system can achieve speeds of up to 35m/min while maintaining burr-free, clean edge precision without material jamming or secondary sanding requirements.
    Q: Does machine operation require specialized technical skills?
    No. Thanks to the intuitive touchscreen PLC console, standard workshop operators can master full machine controls within 30 minutes of basic training.
    Q: Can frequently used duct specifications be stored in the system?
    Yes, the PLC interface allows operators to store common duct diameters and lengths as quick presets for streamlined, one-click production cycles.
    Q: What steps are involved in the standard roll forming process?
    The standard workflow follows manual coil feeding, automatic leveling/straightening, 10-station continuous roll forming, hydraulic precision cutting, and automated finished product discharging.
    Q: How long does it take to switch between different duct diameters?
    Thanks to the quick-change patented mold structure, switching between duct diameters takes only a few minutes instead of hours.
