TDC Flange Forming Machine with Integrated Corner – Roll Forming & Punching Line for Duct Flanges

This machine integrates six major functions into a single unit: servo feeding, hydraulic round hole punching, square hole punching, cold bending, notching and cutting [see quotation document]. From loading the coil to the output of finished flange strips, all processes are completed continuously on a single machine without the need for manual intervention. The PLC control system precisely coordinates the movements of each workstation, ensuring consistency in batch production.

This machine is capable of processing sheet metal up to 1.5 mm thick, enabling the processing of thicker sheets compared to models commonly available on the market, which typically handle thicknesses ranging from 0.5 to 1.2 mm [see quotation document]. For large-scale ductwork projects requiring higher flange strength, thick-sheet flanges provide superior structural support and sealing performance. Customer Benefits: The ability to undertake a wider range of orders, including large-scale ductwork and engineering projects with high-strength requirements.

The flange strips produced by this equipment are formed with integrated corner brackets during the manufacturing process. The four corners of the finished flange strips already feature complete corner bracket shapes, allowing them to be used directly for duct connections without the need to purchase and install additional corner brackets, as is the case with standard TDC flanges. This design significantly reduces on-site assembly procedures and the cost of purchasing fittings. Customer benefits: Eliminates the cost of purchasing corner brackets, saves on labour costs for fitting them, and enables flange connections to be completed in a single step.

Each unit undergoes comprehensive integrated testing prior to dispatch—including verification of feed accuracy, punch position calibration, forming dimension inspection, and confirmation of punching and cutting precision. Complete technical documentation (installation drawings, circuit diagrams, operating manuals and video tutorials) is provided, enabling customers to install the equipment themselves. On-site support can be arranged via our engineering services (subject to a fee). A 12-month warranty is provided, with spare parts dispatched free of charge via express delivery during the warranty period, alongside lifetime online technical support.
