Key Features
The Delta servo drive system controls feed length and forming position with repeatable accuracy, ensuring each angle steel flange meets tight dimensional tolerances required for leak-free rectangular duct connections.
A forming speed of 15 m/min allows the line to keep pace with downstream duct fabrication equipment, eliminating the flange supply bottleneck that slows many rectangular duct workshops.
With a thickness range of 2–4 mm and width range of 50–90 mm, the line handles a broad selection of angle steel profiles on one machine — reducing the need for separate equipment for different flange specifications.
At 3,000 kg, the machine frame is built to absorb the forming forces of thicker gauge steel without flex. Linear guide rails and machined forming assemblies maintain alignment over years of daily use.
The integrated control panel provides clear digital readouts for speed, count, and fault diagnostics. An emergency stop button and enclosed electrical cabinet meet standard industrial safety requirements for sheet metal production environments.
