Abstract

A method for producing a structural component from an organometallic sheet includes a first step in which the organometallic sheet is preheated, introduced into a tool and subsequently re-formed. In a second step, a region of the re-formed organometallic sheet is heated. In a third step at least the heated region of the re-formed organometallic sheet is re-formed further in such a way that it enters into a material bond with a further region of the organometallic sheet to form an at least partly closed hollow profile. A device for carrying out the method for producing a structural component from an organometallic sheet and a structural component produced by the method also are described.

First claim

The invention claimed is:

1. A method for producing a structural component from a thermoplastic sheet, the method comprising:
in a first step, preheating the thermoplastic sheet, introducing the thermoplastic sheet into a tool, and subsequently shaping the thermoplastic sheet by closing the tool;
in a second step, heating a region of the shaped thermoplastic sheet and injection molding a thermoplastic material around the thermoplastic sheet within the tool when the region is heated; and
in a third step, opening the tool and moving at least the heated region of the shaped thermoplastic sheet with a slide to further shape the thermoplastic sheet after the tool is opened such that said region enters into a material bond with a further region of the thermoplastic sheet to form an at least partially closed hollow profile.

2. The method as claimed in claim 1 , further comprising attaching the thermoplastic material to a surface of the thermoplastic sheet with a material bond.

3. The method as claimed in claim 1 , wherein, by the shaping process, the thermoplastic sheet is shaped into a partial shape of the structural component according to the first step, and, by the further shaping process, the thermoplastic sheet is shaped into a final shape of the structural component according to the third step.
