摘要

Production of a housing (1) comprises pressure die casting or transfer molding a metallic material so that the material heated to a thixotropic temperature is injected into the tool mold in the thixotropic state. Preferred Features: The housing is made from an aluminum or magnesium alloy, preferably a magnesium alloy containing additions of (in wt.%) 8.5-9.5 aluminum, 0.17-0.40 manganese, 0.45-0.90 zinc, not more than 0.05 silicon, not more than 0.025 copper, not more than 0.001 nickel and not more than 0.004 iron. The housing has a reinforcing structure (4), preferably made from ribs.
