Plate bending

Kersten Europe plaatbuigen

Every material has unique properties that require an appropriate bending technique. Kersten has the necessary expertise and cutting edge machinery to bend both ferrous and non-ferrous alloys to customer-specific hulls, shells, cylinders, conical segments and cones.

For this we use our three and four roll roller machines and the powerful 2400T PowerPress. This choice depends on the sheet or plate thickness, material type and the (small) diameter of the cylinder/cone. Thanks to recent investments in our machinery, we can form even larger and thicker plates. Metal sheets and plates with a thickness of 1 to 150 mm and a width of up to 3.500 mm can be curved using our advanced machines.


    Plate rolling

    To roll metal sheets and plates, a complete series plate rollers with three or four rolls are used. We roll the sheets and plates of various material grades with thickness 1 to 120 mm and a width of 3-3.5 meters. Sheet and plate thicknesses up to 40 mm can be rolled without excess length. To roll thicker plates, excess length is required. Kersten  can advise you about how to limit excess lengths to a minimum.

    The rolling process is explained in the following animation. It shows the cutting of the blank sheet (including welding preparation), followed by rolling, welding the longitudinal seam, calibration and the application of a 3D cut contour. Having this all carried out by one party saves you time and transport costs.


    Press braking thick walled plates

    Where even thicker cylinders, cones or shells are required, Kersten Europe uses the powerful 2400T Power Press. This press braker bends plates of up to 150 mm thick and 3.3 meters wide. The machine is very accurate and is mainly used for (bending) thick-walled cones. The machine only requires a one off set up, making it particularly suitable for small to medium size series with constant radii.


    Special materials

    When a product has specific requirements, such as a specific abrasion or corrosion resistance and/or heat resistance, we at Kersten take this into account. Special alloys such as Creusabro, Hardox, Duplex, Inconel and Clad materials are a solution in such cases. These materials can also be curved in one of our production sites into cylinders or cones.

    Special shapes

    Kersten receives an every increasing amount of requests to bend materials to a wide variety of shapes:  thin and thick walled cones, concentric and eccentric cones, reducers from square to round, column plates and curved segments.

      Additional processing

      Besides dealing with the bending work, Kersten undertakes several additional operations, meaning that we can provide you with complete semi-finished products. We cut out the unfolded patterns from the gross plate whereby (complex) bevels are applied directly. After bending, the longitudinal and circumferential seams are tack welded and welded. Welding is done according to quality standards, including EN15614-1, EN3834-2, AWS, EEMUA, DIN 18.800-7 cl. E, EN1090 exc 4. We perform TIG, MIG-MAG and submerged arc (single and twin) welding.

      Where required, we can provide Non Destructive Testing (NDT), such as visual testing (VT), magnetic testing (MT), ultrasonic testing (UT) and X-ray (XT).

      Advanced CNC robot technology is used to cut the curved product (3D) to size and/or holes and slots.


      In short

      • Rolling and press braking plates in ferrous and non-ferrous alloys
      • Manufacturing hulls, shells and cylinders, as well as special shapes such as concentric and eccentric cones, reducers, column sheeting and corner segments.
      • Capacities: from 1 through 150 mm thick and up to a maximum of 3.500 mm wide.
