MFM-Multifunction Machine

Production hall interior view with precast concrete elements

The multifunctional straightening, cutting and bending machine MFM offers maximum flexibility for rebar processing. It is ideal for products with bends at both ends – perfect for stirrups and long bent bars. Thanks to its advanced straightening system, it ensures consistently high end-product quality. The machine processes both single bars up to 16 mm and double bars up to 12 mm. The automatic guide sleeve change and ergonomic bending plates guarantee a smooth production process. Additionally, a 3D bending device is available for producing three-dimensional stirrups, enabling not only the production of 2D stirrups but also 3D elements.

Reinforced steel stirrups come in many shapes: bent on one side or on several sides, 3D, closed or open. Rebar stirrups can be subsequently processed in an intertwining or fastening process or welded into mesh and cages.

Stirrups are used as spacers between wall and ceiling elements, in the connection between two walls and in pillars, girders, strip foundations or lintels. They are decisive for the statical properties of the precast concrete element.

What functions does the multifunction machine combine?

The multifunction machine combines several work steps in a single system, including bending, cutting, straightening, and welding. This allows different reinforcement elements to be produced efficiently in an automated process, significantly reducing production times and increasing flexibility when handling varying element types.

What are the main features of the MFM multifunction machine?

The MFM multifunction machine offers straightening, cutting, and bending functions in a compact format, ideal for complex steel products.

For which diameters of steel bars is the MFM multifunction machine suitable?

The machine can process single bars from 6–16 mm and double bars from 6–12 mm.

What are the advantages of the MFM’s 3D bending device?

The 3D bending device enables the production of three-dimensional stirrups, significantly expanding production possibilities.

How does the MFM straightening system ensure high product quality?

The advanced straightening system ensures consistent precision and high end-product quality through optimized control.

What applications do stirrups and bent bars have in the construction industry?

Stirrups are used as spacers between precast elements and in structural applications that are crucial for the structural integrity of buildings.

Pluristar

The Pluristar is an automatic stirrup bender, straightener, and double-bending machine in one. It can process wire diameters of 6 – 16 mm. The heart of the Pluristar is the combined straightening system consisting of a roller straightening unit and a rotor straightening unit. This unique combination allows the flexible manufacture of stirrups, straight rebars, and rebars with large bends using just a single machine. Depending upon the given product, the suitable straightening unit is inserted fully automatically. The wire is changed fully automatically or manually, as required. The Pluristar can also be equipped with a 3D bending system allowing not only 2-dimensional, but also 3-dimensional stirrups to be produced.

Overview of bending shapes for reinforcing steel and stirrups – Progress Group bending technology for precast concrete elements

Steel bar or mesh is used to produce reinforcement for precast concrete elements. The bars have a ribbed surface, which ensures optimum interlinking with the concrete. Reinforcement bars are processed either as bar material or direct from the coil. Bars can be linked together into cages or mesh either by a weaving process with linking material (fastening) or by being welded. They can be straight, or bent single-sided or multi-sided.
