10 MN light metal extrusion press
With a maximum press force of 10 MN and available recipient diameters of 125 mm and 146 mm, the institute has a short-stroke front-loading extrusion press with a specific press force of 815 MPa and 600 MPa respectively. An air circulation chamber furnace with optional inert gas supply for ingot heating, a further furnace for die heating outside the extrusion press and a 14 m long roller conveyor with a strand puller enable industrial extrusion tests to be carried out. As an option, it is possible to install the institute's own device for spray water cooling near the press die.

Description of the system
The short-stroke front-loading extrusion press on an industrial scale can be operated in both direct and indirect extrusion processes. The main piston or punch can be moved between 0.2 mm/s and 30 mm/s in steps of 0.01 mm/s. Various aluminum and magnesium alloys can be processed for research purposes and small series production. For this purpose, dedicated crucibles are available, which can be heated up to a temperature of 490°C. In addition to simple round and square bars, flat, U, I, L profiles, and tubes in various dimensions, close collaboration with various tool manufacturers also allows for the pressing of profile geometries tailored to the application, e.g., using chamber tools. The extrusion press has been expanded with an in-house extrusion device, which enables torque-controlled extraction speeds of up to 37.2 mm/s with an adjustable extraction force of up to 1450 N.
Specially developed composite extrusion processes enable the production of asymmetrically reinforced square profiles as well as hollow profiles, where a steel or titanium tube is encapsulated with aluminum.
The existing furnace technology allows not only the tempering of tools and press blocks but also the performance of various heat treatments (homogenization, solution annealing, annealing, etc.) of profiles up to a length of 500 mm. In addition to industrial standard alloys, the IW Light Metal Foundry also manufactures press blocks from application-specific experimental alloys of aluminum or magnesium, which can be processed into profiles for small series production on the 10 MN extrusion press.
