Sheet Metal Forming & Hydraulic Presses

Presses for industrial sheet metal forming

SIEMPELKAMP designs and builds hydraulic presses for sheet metal forming when thickness, material, and dimensions push conventional processes to their limits. Whether heavy plate up to 400 mm for pressure vessels, medium plate for large-diameter pipes, or high-strength steels for load-bearing structures, our presses are individually engineered to meet the requirements of each specific product. With more than 130 years of experience in press manufacturing and our own spheroidal-graphite iron foundry, we have the technological depth to supply complete production lines from a single source.

Our portfolio of presses for sheet metal forming

From leveling heavy plate to forming half-shells and producing longitudinally welded large-diameter pipes, our sheet metal forming machines cover the entire range of industrial sheet metal processing.

Sheet metal forming

Leveling press

Our leveling presses process plates up to approx. 300 mm thick made of materials with tensile strengths up to 1,300 N/mm² in cold or hot operation at sheet metal temperatures up to 600 °C. The presses are equipped with one or more leveling rams that can be moved in a coupled or independent mode. Integrated sheet metal handling systems and automatic tool changing systems ensure short cycle and setup times. A stroke accuracy of ±0.2 mm enables leveling precision that exceeds tolerance class S of DIN EN 10029.

Sheet metal forming

U-pipe bending press

Our U-pipe bending presses are the central forming unit in the production of longitudinally welded large-diameter pipes using the C-U-O process. Three to four main cylinders form plates up to 18 m in length with independently controlled horizontal and vertical forming axes to achieve the optimum U-shape for subsequent O-forming. The heavy structural components and tools are manufactured in our in-house foundry. Innovative drive systems are arranged directly on the press.

Sheet metal forming

O-pipe bending press

With a press force of 4,000 t per meter of pipe length, our O-pipe bending presses form high-strength steels above X100 to the required roundness at the optimum reduction ratio. The patented parallel control of the moving beam ensures a uniform pipe gap of ±1 mm/m over the entire pipe length. Modular half-shell tool systems made of spheroidal-graphite iron enable the production of different pipe diameters without changing tools, minimizing unproductive auxiliary times.
