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 between two shaping tools under high pressure. Our presses are designed for continuous industrial operation and meet the stringent requirements of the aerospace, defense, and energy industries as well as general machinery and plant engineering.

Industries and certifications: Aerospace, oil, gas & energy technology, mining, railway, defense, etc.

SIEMPELKAMP closed-die forging presses with press forces between 15 and 500 MN provide the optimum solution for a wide range of applications. The optimum ratio of press dimensions to press force ensures maximum customer benefit. Excellent process and plant parameters are the key to high dimensional accuracy and reproducibility.

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

The press is used to manufacture rotationally symmetrical components (rotating turbine parts) through to complex component geometries. Typical processes include upsetting, piercing, and backward extrusion. This enables demanding materials such as high-alloy steels, high-performance materials, and titanium- and nickel-based alloys to be processed safely and with stable processes.

The press is designed for continuous industrial operation and meets the highest requirements of the aerospace, defense, and energy industries as well as general machinery and plant engineering.

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 in combination 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 castings

With our own foundry, we manufacture large and complex castings with a weight of up to 320 tons in-house. This shortens manufacturing times, reduces external dependencies, and ensures continuous 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 through on-site installation to 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. Over 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.
