METHOD FOR MANUFACTURING A REINFORCED BI-METALLIC CASTING COMPOSITE AND APPARATUS FOR MANUFACTURING A REINFORCED BI METALLIC CASTING COMPOSITE

摘要

A method for manufacturing a reinforced bi-metallic casting composite is provided, wherein at least one metallic insert (2) is provided in a die (3) and a metal over casting step is performed, wherein, by means of said metal over-casting step, an over-cast metal (14) is casted at least partly over said at least one metallic insert (2). The method comprises the following steps: a) providing said at least one metallic insert (2) being in a preformed condition; b) introducing said at least one metallic insert (2) being in its preformed condition into said die (3); c) holding said at least one metallic insert (2) being in its preformed condition in a predetermined position in said die (3); d) performing a closing operation of said die by means of a closing element (9); e) performing a deformation operation, wherein, by means of said deformation operation, said at least one metallic insert (2) being in its preformed condition is deformed from its preformed condition into a casting condition; f) performing said metal over-casting step, wherein said over-cast metal (14) is casted at least partly over said at least one metallic insert (2) being in its casting condition; g) solidification of said over-cast metal (14); and h) extracting said at least one metallic insert (2) together with said over cast metal (14) from said die (3). An apparatus (1) for manufacturing a reinforced bi-metallic casting composite, preferably for performing said method, is also provided, comprising: a die (3), wherein said die comprises a moulding cavity (4); and a closing element (9) being movable in a closing direction (8) for closing said moulding cavity (4). The apparatus (1) further comprises: at least one actuator (11; 5) being adapted to perform a deformation operation to a metallic insert (2) when being arranged inside of said moulding cavity (4), wherein said at least one actuator (11; 5) is a mechanical actuator, a hydraulic actuator, a pneumatic actuator, a magnetic actuator or an electric actuator.
