Hot Extrusion

The technology known as hot extrusion can be used to produce profiled bars with complex geometries in small or large volumes and in difficult-to-form materials. During hot extrusion a round steel billet is pre-heated and, after leaving the furnace, pushed through a forming die into a shaped bar using a ram with an extrusion force of approx. 2000 tons.

From round to finished profile in only one step

Hot extrusion not only allows to manufacture elaborated open steel profiles but as well seamless hollow profiles. Extruded profiles often become the preferred solution when the design is very complex, e.g. necessity for under cuts and/or when small production runs are requested, especially on mid to large size profiles. Hot extrusion is highly versatile and we can transform a wide variety of grades, such as carbon steel, stainless steel, nickel base alloy and titanium alloys into special profiles.

Ordering hot extruded bars

The profiles are supplied as bars in any length up to 16.800 mm. There are no requirements on min. quantities and even one-bar-prototypes can be produced.
