Abstract (en)

In a process to fabricate a cast metal component with integral functional elements e.g. sensors or temperature-sensitive functional elements, the heat-screened element is pre-positioned within a casting form cavity. The metal is then cast in the conventional way. The position of the form is so chosen that the flow speed of liquid metal is low in the vicinity of the functional element. Also claimed is a suitable cast assembly.
