GDF Duplex Duct Flange Forming Machine

1. The machine is equipped with 24 precision roller stations specifically engineered for GDF profile geometry. Unlike conventional TDC flange machines that produce separate flange strips requiring manual riveting to duct panels, this machine forms the GDF flange interface directly on the duct panel edge in one continuous process.

2. Panel enters the machine. After passing through 24 stations, both sides of the panel emerge with fully formed GDF flange interfaces. The flange is integrated with the panel — no secondary assembly required. Dimensional accuracy, angle precision, and interface flatness are guaranteed by the machine, not dependent on operator skill.

3. The panel feed width is automatically adjusted by four 1.5 kW servo motors, within a range of 1,200–1,500 mm. Switching between different specifications requires no manual intervention; width settings can be completed at the touch of a button, with the servo system automatically driving the lead screw to the target position.

1. Conventional TDC flange process: form flange strips → cut to size → manually align strips to duct panel frame edge(Has undergone processes such as notching ,beading, cutting, lock forming and bending） → rivet one by one. This requires at least 2-3 skilled workers per line and repeated operations for each duct.

2. The GDF Duplex process: panel enters(Has undergone processes such as notching ,beading, cutting,and lock forming） → 24-station forming → panel exits with integrated flanges→ bending to be air duct. No manual intervention in between. No separate flange strips. No riveting.

3. One GDF Duplex machine with one operator replaces what previously required 3-4 workers. For high-volume continuous GDF duct production, this efficiency gain translates to doubled output and significantly reduced labor costs.

1. Heavy-Duty Frame – Consistent Quality in Batch Production With double 35mm wall plates, 40mm spindle diameter, and approximately 6,000kg machine weight, the machine delivers consistent forming accuracy across long production runs.

2. This machine is built for continuous batch production. The 35mm wall plates, reinforced with strategic bracing, maintain roller alignment under prolonged forming forces. The 35mm spindles ensure drivetrain stability over extended operating hours.

3. For duct shops running continuous shifts, this structural rigidity translates to consistent flange dimensions across every panel — no gradual drift, no frequent recalibration.

1. The equipment comes with a standard 12-month warranty. During the warranty period, should replacement parts be required due to manufacturing defects, these will be dispatched free of charge to the customer’s designated address. We also provide free lifetime technical support; customers can receive online technical assistance for any issues relating to equipment operation, maintenance or troubleshooting that arise during production.

2. For overseas customers, engineers can be dispatched to the factory site according to project requirements to provide services such as equipment installation guidance, commissioning, operational training and instruction on key aspects of routine maintenance. This service capability offers practical value in cross-border equipment procurement, helping customers to shorten the lead time from equipment arrival to production commencement and reduce the risk of early-stage faults caused by improper installation.

3. Throughout the equipment’s entire lifecycle, customers can access technical support and spare parts supply information at any time, without having to worry about finding themselves in a situation where there is ‘no one to ask and no parts to replace’ once the equipment is in operation.
