Multiform Flanging Machine: Cut and Flange Flat, Dished and Elliptical Lids with One Versatile Machine
Not every container is a simple round tank. Oval, elliptical and other non-cylindrical vessels need lids whose edges are bent to exactly the right shape, or the bottom and ceiling will never close cleanly. The SBFM Multiform Flanging Machine, also known as the Ellipse Bending Machine (EBM), is built for this demanding job. It bends the edges of curved and non-convex lids, and it cuts and flanges flat and dished heads for tanks and many other products.

- Typical containers: Low-pressure or non-pressure, thin-walled, non-cylindrical metal containers
What Is a Multiform Flanging Machine?
A flanging machine forms the outer edge of a plate or dished head into a flange, a short, bent rim that lets the lid be seamed, welded or fitted onto a container. In a multiform machine the lid is not limited to a circle. The same machine can follow round, oval and elliptical outlines, which is why it is called multiform.
The Ellipse Bending Machine is designed for the lids that close the bottom and ceiling of non-cylindrical metal containers. The center of the lid stays solid, with no hole, and only the edge is shaped.
How Flanging Gives Lids a Clean, Strong Edge
During flanging, the lid turns or travels along its outline while a forming roll presses against the edge and bends it to the required radius. Hydraulic cylinders supply the pressing force, so the edge forms smoothly and evenly instead of being struck. Forming the edge in a controlled way keeps thinning low and avoids cracks, folds and waves, which matters most on thin-walled lids. The result is a flange with a uniform height and radius, ready for seaming or welding with a tight, leak-resistant fit.
Key Features and Benefits
- Multiform capability: round, oval and elliptical lids on one machine
- Cutting and flanging of flat and dished heads for tanks and other products
- Hydraulic forming force for smooth, repeatable edges
- Solid-center lids with only the edge bent, no hole required
- Rigid frame that keeps the rolls stable and the flange uniform
- Thin-wall friendly forming for light metal containers
- Easy operation that helps operators learn quickly and work safely
Materials You Can Flange
The machine works with thin sheet and plate in carbon steel, stainless steel, aluminum and other formable metals. Maximum diameter and thickness depend on the model and on the material, and harder grades need more force and larger radii. Always confirm capacity for your own material, lid size and wall thickness before ordering.
Applications
- Oval and elliptical tank lids
- Flat and dished heads for storage tanks
- Bottoms and ceilings of thin-walled metal containers
- Low-pressure and non-pressure vessels
- Boilers, heaters and water tanks
- Food, chemical and HVAC equipment
Tips for Perfect Flanges
Good flanging starts with good preparation. Cut the blank accurately, because the flange can only be as even as the outline. Keep the plate clean and free of scale to protect the rolls. Form the flange gradually in several passes instead of forcing the full radius at once, and check height and radius against a template. Allow for springback, the slight return of the metal after forming.
Part of a Complete Sheet Metal Forming Range
SBFM Machinery has built sheet metal forming machines in Konya since 1998. Alongside flanging machines, our range includes hydraulic dishing presses, plate and profile bending machines, pipe bending machines, polishing machines for dished heads and special corrugated and grooved rolls. A single partner can equip your workshop from shells to tank heads, lids and rings.
Why Choose SBFM Machinery?
Machines are designed, cut, welded, machined, assembled and tested in our own facilities, and our quality policy rests on customer satisfaction. We believe we grow together with our customers, so we listen first and recommend the model that fits your work, not simply the largest one. Technical guidance and spare parts help keep your machine productive for years.
How to Choose the Right Machine
- Lid shapes you will make: round, oval or elliptical
- Largest lid size and plate thickness
- Materials and wall thickness of the container
- Control level and production volume
- Available floor space and power supply
Maintenance for Long Service Life
Keep the forming rolls clean, check hydraulic oil level and filters, and inspect hoses and fittings for leaks. Lubricate bearings and guides as described in the manual and protect the machine from scale and chips. A simple preventive routine keeps flanging accurate and reliable for many years.
Frequently Asked Questions
What can the machine do? It cuts and flanges flat and dished heads and bends the edges of curved and elliptical lids for tanks and containers.
Does the lid need a hole in the center? No. The center stays solid and only the edge is formed.
