    LIDING

    Why do professionals choose LIDING flange machines?

    Tiny footprint, huge productivity

    We know workshop space is gold. This machine only takes up 5 square meters—you can tuck it in any corner and still have room for other equipment. One worker can handle feeding, operation and discharging all by themselves, cutting labor costs by 60% compared to manual bending. It’s perfect for small-batch custom orders and bulk wholesale production.
    Unmatched Production Efficiency & Labor Savings

    Built to last with premium materials

    We don’t skimp on the parts that matter. The cutting blades are made of genuine Cr12mov alloy steel, quenched to HRC60-62°, so they cut clean, burr-free edges and last 3x longer than ordinary steel blades. The heavy-duty steel frame and precision-machined gears run smoothly with minimal vibration, even during 8-hour nonstop production.
    High-Grade Materials & Long Service Life

    Accuracy that eliminates waste

    After 20 years of making duct machines, we’ve nailed the forming precision. This machine produces flanges and ducts with consistent dimensions every single time. No more gaps at the joints, no more air leaks, and no more throwing away bad parts. Our repeat customers always say this is the most reliable machine in their shop for tight-tolerance jobs.
    Precise Forming Meeting International Standards

    Dead simple to use, fast support

    The touch screen interface is intuitive—any worker can master it in 30 minutes, no special training required. If you ever run into issues, our technical team responds within 3 hours, and we offer free remote troubleshooting and replacement parts during the warranty period. We also have engineers available to fly to your site for installation and training anywhere in the world.
