Light metal extrusion presses

For producers who manufacture a varied aluminum product mix and small batch sizes, direct extrusion is the preferred solution. Short-stroke, front-loader extrusion presses from SMS group are the perfect choice here. They feature FEM-optimized, pre-stressed press frames in the classic Schloemann lamellar tie rod/pressure box design. That makes the frames highly rigid and ensures both excellent profile quality and a long service life. As a supplement to the press itself, our robust linear billet loaders provide precise and optimized motion sequences during loading.

HybrEx^® extrusion presses consume up to 55 % less energy, while increasing your productivity by up to 20 % at the same time, depending on the application. This qualifies the HybrEx^® extrusion press for our Ecoplants label which denotes economically and ecologically convincing solutions from SMS group.

The new extrusion press generation implements a hybrid drive concept. The HybrEx^® hybrid drive system is based primarily on electric servomotors, which are more efficient, faster, and more precise than the mainly hydraulic machines. The hydraulic drive in the HybrEx^® extrusion presses is used exclusively to generate high forces for the extrusion process, for discard shearing, and for die cassette shifting.

Indirect presses are ideal for extruding aluminum hard alloys such as AA2xxx and AA7xxx. That's because the lack of friction between the billet and container ensures a reduced extrusion force and optimized material flow. These factors are essential for producing sections made from high-strength alloys. You can also choose from our range of extrusion presses that combine direct and indirect extrusion methods. These give you the flexibility to adjust your production to meet current market demands.

Our tube extrusion presses are front-loading or back-loading presses with an internal inline piercing device. Combined with the linear guiding system for the container holder and moving crosshead, this piercing device ensures excellent eccentricity tolerances for extruded seamless tubes.
