Spanish HVAC Manufacturer Integrates Liding GDF Flange Forming Machine for Rectangular Duct Production
An HVAC ductwork manufacturer based near Barcelona, Spain, required an upgrade to their rectangular air duct production line. The company supplies ventilation systems for commercial and industrial projects across the Iberian Peninsula. Previously relying on semi-automated systems, the facility identified three operational constraints:
- Inconsistent flange joint tolerances, increasing manual adjustment time during on-site installation.
- Production speed limitations hindering high-volume output.
- Downtime caused by the need for frequent manual calibration.
To address these parameters, the manufacturer required a GDF flange roll forming machine capable of processing 0.5–1.2mm galvanized steel coils with stable structural output. Following a technical evaluation, the facility integrated the Liding GDF Steel Coil Flange Profile Machine.
The installed equipment is the GDF20 Flange Duplex Machine, manufactured by Foshan Liding Machinery Equipment Co., Ltd.

The equipment configuration addresses the client's production requirements through the following engineering designs:
- Duplex Roll Forming Stations: Servo-driven systems control the deformation of the galvanized sheet, maintaining standard flange joint profiles to ensure duct airtightness.
- In-line Processing: Hydraulic punching and notching modules are integrated to eliminate secondary manual operations.
- Quick-Change Roller Cassettes: Allows for transition between different flange specifications, adapting to mixed-order production schedules.
- PLC Control System: Provides process monitoring and real-time diagnostics to maintain operational consistency.
- Compliance: Built with European-standard safety enclosures, operating under full CE certification.
Following the commissioning phase, the facility recorded the following operational data:
- Tolerance Control: Flange joint parameters remain within standard specifications. The double-coupled flange design aligns with the structural requirements for rectangular ducts, mitigating air leakage risks.
- Output Metric: Continuous roll forming speeds and the removal of secondary manual processes resulted in a measured increase in daily flange production volume.
- Operator Ergonomics: Automatic coil feeding and the PLC interface reduced manual calibration requirements.
Acoustic Emission: Equipment noise levels register within the limits of European workplace regulations.
