Multiform Flanging Machine: Edge Bending for Dished and Flat Covers on Non-Cylindrical Containers

Not every container is a neat round drum. Many industrial vessels are oval, elliptical or shaped to fit a machine, a vehicle or a tight space, and their covers must match that shape exactly. The SBFM Multiform Flanging Machine (EBM) is made for these covers. It bends the side edges of dished or flat covers used to close the top and bottom of low-pressure or unpressurized, thin or thick-walled, non-cylindrical containers, so that each lid meets its container with a clean, even seam.

What Does a Multiform Flanging Machine Do?

A flanging machine turns the outer edge of a cover into a flange, a short bent rim that lets the lid be joined to the container. The word multiform tells you that this machine is not tied to one outline. It can follow different shapes, which is why it suits the many non-cylindrical containers made in industry.

The machine works on the side edges of the cover only. Dished and flat covers are both accepted, so one machine can prepare lids of several styles for several kinds of containers.

Why Shape-Following Flanging Matters

On a round lid, the edge is the same distance from the center all the way around. On an oval or elliptical lid it is not, and the forming tool must keep adjusting as the lid turns. If the tool cannot follow the outline, the flange comes out uneven, with a height that changes along the edge and a joint that needs hand correction. A multiform machine solves this by guiding the forming action along the real outline of the cover. The result is a regular flange all the way around, ready for welding or seaming without extra work.

Key Features and Benefits

• Multiform capability for non-cylindrical outlines, not only circles
• Dished and flat covers processed on the same machine
• Edge bending of side points for lids that close the top and bottom
• Thin and thick-walled containers served within model capacity
• Low-pressure and unpressurized work handled with consistent flanges
• Rigid, welded frame that keeps the forming action stable
• Operator-friendly design that is quick to learn

Materials You Can Flange

The machine works with sheet and plate in carbon steel, stainless steel, aluminum and other formable metals. Maximum lid size 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 cover size, thickness and material before ordering.

Applications

• Oval and elliptical tank covers
• Lids for low-pressure and unpressurized containers
• Machine housings and enclosures with shaped lids
• Fuel, oil and water containers of special shape
• Heater, boiler and ventilation equipment
• Food, chemical and HVAC products

Tips for Perfect Flanges

Accurate cutting is the starting point, because the flange follows the outline of the blank. Keep the cover clean, since scale and burrs leave marks on the surface. Form the flange in several gentle passes instead of one hard pass, and check its height and radius on a template after the first piece. Allow for springback, the slight return of the metal after forming, and handle large lids with proper support.

Part of a Complete Sheet Metal Forming Range

SBFM Machinery has built sheet metal forming machines in Konya since 1998. Alongside multiform flanging machines, our range includes hydraulic dishing presses, plate bending machines, profile and pipe bending machines, polishing machines for dished heads and special corrugated and grooved rolls. A single partner can equip your workshop from covers and heads to shells, rings and pipes.

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

• Cover shapes and the largest outline you will flange
• Dished covers, flat covers or both
• Plate thickness and material
• Production volume and operator skill level
• Available floor space and power supply

Maintenance for Long Service Life

Keep the forming rolls and guides clean, check hydraulic oil level and filters, and inspect hoses and fittings for leaks. Lubricate moving parts 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 bends the side edges of dished and flat covers used to close non-cylindrical containers.

Can it work only on round lids? No. It is a multiform machine made for shaped, non-cylindrical outlines as well.

How do I choose the capacity? Send us your cover shape, size, material and thickness, and our engineers will recommend the right model.
