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.
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.
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.

Frequently Asked Questions
How does LIDING's patented mold system save production time?
Our patented mold system allows you to switch between different duct diameters in just minutes instead of taking half a day. This precision design also reduces steel scrap material by up to 15% for significant cost savings.
What is the maximum cutting speed of the LIDING flange machine?
The integrated high-speed synchronous cutting system can reach speeds up to 35m/min, keeping up with tight deadlines while ensuring clean, burr-free cuts that do not require extra sanding or trimming.
Is specialized training required to operate this machinery?
No, the machine features an intuitive touchscreen PLC console. A standard worker can fully master operations and preset parameters in just 30 minutes of training.
What is the production process for LIDING spiral ducts?
The process consists of: 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.
What does the standard flange production line process involve?
The standard process includes manual coil feeding, automatic leveling and straightening, 10-station continuous roll forming, hydraulic precision cutting, and finished air duct/flange discharging.
