Advanced Flexible Duct Connection Line High Precision Automatic Fabric and Metal Joint Forming Machine for Ductwork
Dongguang Hengfu Roll Forming Machine Co., Ltd. presents a fully automatic flexible connector production line, built for stable, efficient, and high-precision manufacturing of HVAC soft connectors. This all-in-one machine integrates uncoiling, servo feeding, punching, roll forming, cutting, and collecting into a continuous workflow, ensuring consistent product quality, strong stability, and long service life.
This line supports a wide processing range to meet various production needs. It works with galvanized steel sheets of 0.3-0.6mm thickness and processes both metal sheets and fireproof cloth smoothly. The finished flexible connectors can be made in widths from 180mm to 600mm, offering strong adaptability for different duct connection projects.
The machine is constructed with heavy-duty components for industrial-grade durability. It adopts 12 forming stations with Gcr15 rollers coated with hard chrome, ensuring wear resistance and no damage to material surfaces. The frame is made of 80×80 square tube with 14mm thick vertical plates, providing excellent rigidity and low vibration during long-hour operation.
Driven by a 3KW motor and precision reducer, the line runs steadily at 6-8m/min with PLC automatic control for accurate coordination. The transmission system is stable and low-noise, while the hydraulic and servo systems ensure clean punching and precise cutting. The full set of configurations guarantees easy operation, low failure rate, and minimal maintenance.
With professional design and strict quality control, Dongguang Hengfu Roll Forming Machine Co., Ltd. ensures this flexible connector production line delivers outstanding performance and cost efficiency. It comes with one-year warranty and full after-sales support, making it an ideal and trustworthy production solution for modern manufacturing plants.
Frequently Asked Questions
Is the length of the discharge rack adjustable?
Yes, our standard telescopic discharge rack can be adjusted to accommodate sheet materials of varying lengths.
Are customers able to visit the factory to test the machine and observe its performance firsthand?
We welcome customers—or a designated third party—to visit our factory to inspect the machine and conduct trial production runs using their own materials.
How should the machine be stored when not in use for an extended period?
Disconnect the power, clean the machine, apply anti-rust oil, cover it with a dust cover, and store it in a dry environment.
Can the machine produce stainless steel sheets? What are the requirements for the equipment?
Yes, it can; however, it requires reinforcing the forming frames, increasing the hardness of the rollers, and adjusting the forming process.
Can you provide semi-automatic or fully automatic receiving tables?
Yes, optional configurations include pneumatic receiving, hydraulic receiving, and automatic stackers.
