It's easy to sum up the demands of the forging industry: high precision and productivity, perfect microstructure, plus flexible application, batch size, and unit production. This is where we not only meet today's requirements, but also ensure your competitive edge in the future. What puts our hydraulic radial forging machines at the top of the global tree is this: their innovative design, high performance, and intelligent technology.
Concepts




SMI hydraulic forging machines
SMI is an automatically controlled and hydraulically driven 2-ram forging machine with integrated manipulators and centering devices for automatic operation. It is ideal for the mass distribution of hot forgings used for the closed-die forging. It is capable of forging all materials that are normally forged using open-die forging equipment.
Manipulators
Our manipulators for forging machines are particularly robust. Why? Because they offer you not only high load-bearing capacity, but also precise interaction between the manipulators and the forging machine. That's crucial for a perfect forging result.
The manipulators move in sync with the machine - for a fast and smooth forging process. They come with hydraulically driven tongs. We specially designed the tong peel as a hollow shaft so you can also use a mandrel forging device, e.g. for tubes.




Technology
Innovative hydraulic cylinders
Maximum performance with stroke sequencesThese virtually maintenance-free press cylinders incorporate our patented technology. Here is the basic principle: a servo-controlled pilot cylinder is followed by the working piston. This pilot cylinder controls the forming rate and return stroke. That means you achieve pinpoint accuracy - every time.
COMFORGE®
Intelligent technology packageWhat ComForge® does for you is precisely calculate your pass schedules. It takes into account everything from cross-sectional shape to forging process as well as your specific requirements (e.g. fine grain structure). The intuitive user interface makes it easy to input all parameters:
- Geometry of the initial and final dimensions
- Material quality of the forging
- Tool and machine parameters
- Deformation parameters
- Furnace temperature




Forging railroad axles
How to save energy and timeUsing our SMX hydraulic radial forging machine, you can forge up to three axles from a single ingot in just one heat. This means no process interruption for intermediate heating. That not only boosts productivity, but also cuts energy consumption. The hydraulic radial forging machines with fully synchronized manipulators forge the workpieces through to the core over the whole length. Simultaneous loading and unloading ensure a faster process and higher output. Here is how: as the forged ingot is removed on the unloading side, a new ingot is already clamped onto the loading side.




Forging thick-walled tubes
High straightness, minimum eccentricityTo help you boost your business, SMS group modified and extended its proven SMX concept to include tube forging. Specifically, we expanded the plant layout to incorporate a third manipulator that holds a mandrel bar. Also integrated are conically shaped tools that ensure high-quality tube surface finishes. The infeed movement and the turn angle of the manipulator are designed for an optimum material flow. The tube forging process consists of a single pass. Even if you process extremely eccentric mother tubes, you still produce finished tubes with low eccentricity and high straightness.
