<p>In a process for producing formed parts made of an aluminum alloy, the aluminum alloy is exposed to high shearing forces in a mixing and kneading machine (30), having a housing (31) with a working space (34), which is surrounded by an inner housing sleeve (32), and a worm shaft (36), which rotates about a longitudinal axis (x) and oscillates along the longitudinal axis (x) in the inner housing sleeve (32) and is interrupted circumferentially to create individual kneading blades (38), with axial passage openings (40) between the kneading blades (38), and with kneading projections (42), which project from the inner housing sleeve (32), protrude into the working space (34) and pass through the axial passage openings (40), wherein liquid aluminum alloy is fed to the working space (34) at one end of the housing (31) and, at the other end of the housing (31), is removed from the working space (34) as partially solid aluminum alloy with a predefined solids content and is processed to formed parts, wherein the solids content of the aluminum alloy in the working space (34) is set to the predefined solids content by cooling and heating the working space (34) in a targeted manner.</p> |
