Flange Rolling with PBC Flange Rolling Machine

With unmatched bending power and stability, PBC ensures reliable results even for heavy-duty materials and large diameters with flat bars and angle ring flanges. 

The flange rolling machines for PBC are the best solution designed to roll bending flat bar and angle iron into precision flanges. Whether you’re producing flat flanges for ductwork(even Heavy-Duty wind power, gear manufacturing) or angle ring flanges for industrial piping, PBC delivers reliable performance and consistent quality.

Full Set of Combination Dies for Immediate Use

Unlike other flange bending machines that require separate tool purchases, PBC comes equipped with a full set of combination dies, ready to handle both flat bar and angle steel flanges out of the box. This built-in tooling package saves cost, reduces downtime, and makes setup faster for every job.

In addition, PBC provides superior bending capacity compared to similar-class machines. With higher torque and reinforced frame design, it effortlessly handles large-section profiles and heavy materials, offering the strength and flexibility required for challenging flange projects.

PBC’s design ensures precise X-X axis roll bending for flat bar flanges and integrates an Anti-Twist Correction System to solve common issues during leg-in angle flange bending.

Flange Rolling for Heavy-Duty Applications

Flange rolling is used for producing heavy-duty flanges, which have wide applications in industries ranging from offshore wind power to gear manufacturing and pipeline engineering. Rolling such large flanges requires specialized equipment, such as giant profile bending machines capable of producing non-standard size flanges, including those with thicknesses up to 340mm and very large diameters.

Customized Solutions for Heavy Flanges

For rolling heavy-duty flanges, such as the standard PBC-700 model that handles flanges with thicknesses up to 240mm, we can also customize machines that handle flanges with thicknesses exceeding 300mm according to customer needs. These profile bending machines need to have a more compact geometric structure, equipped with extended card clamps to reduce roll shaft deformation, and special roll shafts designed for heavy-duty applications to ensure both forming accuracy and equipment longevity.

With its powerful specs, built-in tooling, and profile versatility, PBC stands out as a top-tier flange rolling machine for industrial applications.

Free Flat Bar Bending Calculator

To further support your bending operations, we also provide a free Flat Bar Bending Calculator to help estimate bending force, radius, and material requirements. This tool is ideal for engineers and fabricators who need fast, accurate calculations before production. Whether you’re working with mild steel, aluminum, or stainless flat bars, it simplifies planning and ensures you get the most out of your flange bending machine.
