Closed-die forging presses up to 500 MN

SIEMPELKAMP closed-die forging presses

Closed-die forging is a metalworking process in which a workpiece is formed under high pressure between two shaping tools. Our presses are designed for continuous industrial operation and meet the stringent requirements of the aerospace, defense, and energy and general machinery and plant engineering industries.

Industries and certifications: Aerospace, Oil, Gas & Energy Technology, Mining, Railway, Defense, etc.

With press forces between 15 and 500 MN, SIEMPELKAMP closed-die forging presses provide the optimum solution for numerous applications. The optimum ratio of press dimensions to press force ensures maximum customer benefit. Best-in-class process and plant parameters are the key to high dimensional accuracy and reproducibility.

SIEMPELKAMP supplies hydraulic closed-die forging presses for a wide range of applications. Depending on the application, guidance accuracy, cycle time, eccentricity, and speed are precisely matched to each other. Depending on customer requirements, we supply the presses in above-floor or pit-mounted design – and, if desired, as a complete solution from the press cell through to the forging plant.

The press supports a wide range of component geometries, including circular, ring-shaped, structural, and rotationally symmetrical shapes. Typical processes include upsetting, piercing, and backward extrusion. The press is designed for continuous industrial operation and meets the stringent requirements of the aerospace, defense, and energy and general machinery and plant engineering industries.

Forging solutions with a holistic approach

Digital planning expertise

With our digital twin approach, we support every project from the initial idea and system design through simulation, engineering, and virtual commissioning all the way into production. This enables a seamless transition from the digital model to the real machine, minimizes project risks, improves software quality, and accelerates commissioning. As a result, the full performance of the plant is available right from the start.

Exceptional precision and reproducibility

The precise control of speed, force, and synchronization, combined with automated control of the forming speed, minimizes process fluctuations and enables highly precise and reproducible forming results. This results in outstanding dimensional accuracy, consistent material properties, and reliably high production quality.

Proven performance with the most demanding materials

Our forging press technology is designed for demanding applications with high-performance materials such as Ti-5553. Precise control of the forming process ensures reliable material flow and consistent results, even under the most demanding process conditions.

In-house expertise in large and heavy castings

With our own foundry, we manufacture large and complex castings weighing up to 320 tons in-house. This shortens manufacturing times, reduces external dependencies, and ensures end-to-end control over component quality, engineering, and delivery dates.

Proven project experience

Decades of experience in the worldwide delivery and installation of XXL presses mean that we understand the challenges far beyond press manufacturing itself. From heavy-load logistics and special transports to on-site installation and commissioning, our teams coordinate the entire implementation. This ensures reliable project execution even for particularly demanding large-scale projects.

Expertise combined. Projects clearly coordinated.

Presses, automation, process technology, large-scale machinery, foundry, and service in an integrated range of services. A single central contact person brings together all relevant expertise and ensures clear responsibilities across the entire project scope. This creates efficient workflows and seamless collaboration between all trades.

Over 100 years of experience. More than 700 large presses worldwide.

More than a century of engineering expertise and over 700 large presses installed worldwide form the foundation for reliable forging technology. Our experience with generations of press technology and complex applications makes us a proven partner for demanding forging projects.
