A method for producing a frame-like structural member

2008 
The invention relates to a method for producing a frame-like structural component (2) with opening (7), in particular a backrest structure or a seat frame structure of a vehicle, using a light alloy by casting. In such a method, the invention provides the following: a. Supplying the molten metal to at least two heated melt leads (11, 11), the melt outlets (12, 12) open directly into a channel of a mold, which serves to receive the melt for the structural component, b. Feeding the molten metal from the melt supply lines in the channel of the mold, wherein the melt streams flow opposite to the channel. The process enables the production of a structural component that needs to be reworked at best insignificantly after casting and in which, in defined regions of the frame increased mechanical characteristic values ​​can be displayed.
