Plate Metal Bending

Sheet metal is generally made by hand or die stamping to plastically deform some metal sheets to form the desired shape and size, and can be further welded or a small amount of mechanical processing to form more complex parts. Common items-such as chimneys, tin stoves, and car shells commonly used in daily life, are all sheet metal parts.

Plate metal bending is a chipless process in which sheet metal is formed by the application of mechanical force. In our company bending is carried out with the use of five CNC-controlled press brakes.

Bending of large and small parts

Bending is one of our most important processes in plate metalworking. With our machines we can form plate metals in all common formats according to your requirements. Bending of particularly thick material thicknesses is also possible for us.

Press capacity Max. bending length Max. material thickness (S235JR)
2,500 MT 16,000 mm 25 mm / 16,000 mm
600 MT 8,000 mm 12 mm / 8,000 mm
300 MT 6,000 mm 5 mm / 6,000 mm
225 MT 3,500 mm 6 mm / 3,500 mm
36 MT 1,020 mm 5 mm / 1,030 mm

This is how plate metal bending works

Bending, also called folding and is one of the most important processes in plate metalworking. A press brake has an upper tool (punch) and a lower V- or U-shaped tool (die). The plate metal is placed between the tools for the bending process. By lowering the upper tool in a controlled manner, the plate is pressed into the die and a bent is is being made. This process is also called free bending. Other methods for bending plate metal are bending with embossing and three-point bending.

The CNC controls of our machines precisely regulate the lowering depth. This allows the plate metal to be bent to different angles. However, the bending process involves some details which must be observed. Not every metal behaves in the same way when it is exposed to large forces. Some types of material spring back more strongly after bending or can only be folded with bending film due to their high-quality surfaces.

The computer control also allows the simulation of bending processes. In this way, the lowering depth of the punch can be optimally planned without having to make test bends. The CNC control also helps to maintain the minimum bending radius.
