High-Speed VCD & Fire Damper Frame Production Line | China Suppliers Factory - LD-FD06 for HVAC Solutions

,

With 30 years of expertise in the cold roll forming equipment industry, we understand the challenges faced by large-scale HVAC manufacturers in China. Standard frame machines often fall short in meeting the tight deadlines of million-dollar commercial projects, as they require frequent manual adjustments and produce inconsistent dimensions that can lead to costly assembly delays. Introducing the Liding LD-FD06, our flagship frame production line designed specifically for high-volume factories. This state-of-the-art machine features 22 precision forming stations and automatic multi-hole punching, enabling the production of perfectly finished damper frames at an impressive speed of 8m/min. Say goodbye to bottlenecks, rework, and missed deadlines. As a leading supplier, we provide the ultimate production solution tailored for large commercial and industrial HVAC projects, ensuring efficiency and quality.

    liding Why choose this machine?

    Built for 24/7 nonstop operation

    This is not a hobby machine for small workshops. It’s designed to run around the clock for months on end without breaking down. The 25-meter heavy-duty steel frame eliminates all vibration, and the 23KW industrial motor delivers consistent power even at full load. Our customers report running this machine 16 hours a day, 6 days a week, with zero unplanned downtime.
    Unmatched Production Efficiency & Labor Savings

    One pass produces fully finished frames

    Unlike basic machines that only form and cut, this line punches all necessary holes automatically in one continuous process. No more stopping to manually drill holes, no more misaligned holes, no more wasted time. What used to take three separate operations now happens in one smooth pass.
    High-Grade Materials & Long Service Life

    Perfect consistency across every single frame

    With 22 precision forming stations, every frame comes out exactly the same, every single time. The dimensional tolerance is ±0.2mm, which means your blades will fit perfectly on the first try. No more grinding edges, no more forcing parts together, no more assembly line delays.
    Precise Forming Meeting International Standards

    Scales with your growing business

    As your orders increase, this machine grows with you. It can handle everything from small residential frames to heavy-duty industrial fire damper frames. We can also upgrade it with servo fly-cutting, automatic stacking, and other features as your production needs expand.
