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.
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.
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.
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.

Frequently Asked Questions
How much space does the LIDING flange machine occupy?
The LIDING flange machine features an extremely compact design, requiring only 5 square meters of workshop space. This small footprint allows you to place it easily in any corner while keeping plenty of room open for other equipment.
How does this machine help in reducing labor costs?
It is designed for single-operator efficiency. A single worker can comfortably manage coil feeding, operation, and finished product discharging, which cuts labor costs by up to 60% compared to traditional manual bending operations.
What materials are used to ensure the durability of the cutting blades?
We construct our cutting blades using genuine Cr12mov alloy steel, quenched precisely to HRC60-62°. This premium material ensures clean, burr-free edges and delivers a service life that lasts 3 times longer than standard steel blades.
Is the machine easy for standard operators to run?
Yes, the machine features an intuitive touch screen interface. Any worker can master its controls and daily operations within 30 minutes, removing the need for specialized technical training.
What kind of technical support does LIDING offer after purchase?
We provide a rapid 3-hour response time from our technical team. During the warranty period, we offer free remote troubleshooting and replacement parts. Additionally, we have engineers available to travel globally to your site for installation and hands-on training.
What is the workflow of the standard production process?
The automated process flows smoothly from Manual Coil Feeding, to Automatic leveling and straightening, through a 10-station continuous roll forming system, followed by Hydraulic precision cutting, and finally Finished air duct/flange discharging.
