Automatic Duct Flange Machine - China Suppliers | Ventilation & Fire Pipe Flange Factory V4-2 for Thin Materials
Why do professionals choose LIDING flange machines?
Optimized for thin materials, unbeatable forming accuracy
Most flange machines on the market work fine with thick materials, but they struggle with 0.4-0.6mm thin galvanized sheets—they run off track, wrinkle, and leave loose joints. We’ve tweaked the roll profile curve for over a decade, so thin materials run as steady as a rock. The dimensional error of the formed flange frame is controlled within 0.5mm, and the joints fit perfectly. No need to hammer and correct on site, just install directly. The scrap rate is more than 10% lower than ordinary machines.
4-ton heavy frame, built for nonstop operation
Don’t underestimate this 4-ton weight—it’s all solid thick steel plate welded together. Many cheap machines cut corners on the frame, making them light and wobbly when running fast, with loud noise and frequent breakdowns. Our machine runs at full 6m/min for 8 hours straight, as stable as if it’s rooted to the ground. It has low vibration and low noise, so workers can work comfortably next to it, and the failure rate is almost negligible.
Ridiculously easy to operate, saves you the salary of a senior technician
The imported touch screen interface is crystal clear, all parameters are marked in English, and common flange sizes can be saved as presets. No need to hire expensive senior technicians. Any ordinary worker can master it after watching a 30-minute video and practicing twice. One person can handle the whole process of feeding, production and discharging, cutting labor costs in half directly.
No hassle after-sales, respond within 3 hours
The worst thing for construction projects is a broken machine with no one to fix it, delaying the schedule. Our technical team is online 24/7, responds to messages within 3 hours, and provides free remote troubleshooting. All wearing parts are replaced for free during the warranty period. If on-site service is needed, our engineers can fly to any country in the world, providing one-stop installation, commissioning and training.
Standard Production Process
Frequently Asked Questions
Q: How does the LIDING flange machine perform with thin materials?
Unlike standard machines that struggle with 0.4-0.6mm thin galvanized sheets, our machine features an optimized roll profile curve refined over a decade. This ensures thin materials run smoothly without running off track, wrinkling, or leaving loose joints.
Q: What is the forming accuracy of the finished flange frames?
The dimensional error of the formed flange frame is strictly controlled within 0.5mm. The joints fit perfectly, meaning there is no need for manual correction or hammering on site, allowing for direct installation.
Q: Why is the 4-ton heavy frame construction important?
The solid, thick welded steel plate frame ensures maximum stability during high-speed operations. Running at a full 6m/min for 8 hours straight, it minimizes vibration and noise, leading to a negligible failure rate compared to lighter, cheaper models.
Q: Is the machine easy to operate for non-technical workers?
Yes, it is designed for ease of use. It features an imported touch screen interface with all parameters in English and preset options. An operator can master the entire production process after just 30 minutes of training.
Q: What kind of after-sales technical support do you provide?
We offer 24/7 technical support with a guaranteed response within 3 hours. We provide free remote troubleshooting, free replacement of wearing parts during the warranty period, and global on-site engineering services for installation and training.
Q: What is the standard workflow of the production process?
The automated line runs as follows: Galvanized Steel Coil Loading → Automatic Feeding & Leveling → 14-Station Continuous Roll Forming → Hydraulic Precision Fixed-Length Cutting → Finished Flange Frame Automatic Discharging.
