The invention relates to a procedure for manufacturing a frame-like structural component (2) with an opening (7), especially a recliner back structure or a seat frame structure of a vehicle, using a light metal alloy by means of casting. With such a procedure, according to the invention, the following is provided: a. Feeding of the molten metal to at least two heated melt feed-in guides (11, 11), whose melt outlets (12, 12) empty directly into a channel of a casting form, which serves to admit the melt for the structural component, b. Feeding of the molten metal from the melt feed-in guides into the channel of the casting form, whereby molten streams flow in opposite directions in the channel. The procedure makes it possible to produce a structural component, which, after casting, in any case needs no significant re-working, and in which, in defined areas of the frame, enhanced mechanical characteristics can be featured.
