Double wheel spinning flanging is a technique used for creating flanges and shaping the bells of cylindrical products. This process involves securing the edge of cylindrical shaped items with two rollers as well as punching of flange holes. By applying a precise angle and rotational clamping force, cylindrical products can be shaped with flanges at 90 degrees or other specific angles. Subsequently, a turning tool is used for trimming, ensuring a flawless outline. For successful spinning flanging, it is crucial to maintain the material quality, particularly in terms of the cylindrical shape's ovality and the welding integrity, as these factors significantly influence the stability and quality of the clamping.

This equipment is capable of processing ducts, cones, and plates made of steel up to 16mm thick. It's perfectly suited for producing components for both axial and centrifugal fans, including fan casings, impeller casings, inlet bells, inlet cones, shrouds, bell mouths, and flanges. Additionally, it offers the functionality for precise punching of flange holes
