Summary:The process comprises: definition of the final hollow part in its internal portion after forging with deformation of solid or thinned-down sections; modelling of the solid or thinned-down sections; formation of the thinned-down sections by recyclable single-material cores positioned at places requiring zones with a thinned-down section, and modelling of the cores; after modelling, definition of the semi-finished product and of the cores in their initial forms having a different configuration from the forged cores; after casting of metal around the cores, in the prior initial form, striking of the semi-finished product with its cores resulting in the part and its cores being deformed from their initial shapes to their final shapes; fettling of the burrs; and removal of the cores.
