A method of casting an assembly is provided that includes forming a structural insert, over-molding the structural insert with a temporary core, and positioning the over-molded structural insert within a cavity of a casting die. The over-molded structural insert is cast within a part, to form the assembly, and the temporary core is removed. The method may also include a temporary core configured to define an alloy flash trim location or locating features to position the structural insert within the cavity of the casting die. Further, the temporary core may define shared features with the structural insert. The part and structural insert may be dissimilar materials such as a part of an aluminum alloy material and a structural insert of a steel alloy material.

Embodiments of the present technology include molding processes for metallic foams, apparatuses, and products. An example method includes placing an uncompressed charge of conductive metal foam into a cavity disposed on a first tool, wherein the first tool is located on a first portion of a compression mold apparatus, translating the first portion of the compression mold apparatus towards a second portion of the compression mold apparatus so as to compress the uncompressed charge of conductive metal foam, creating a compressed charge of conductive metal foam, and overmolding around and through the compressed charge of conductive metal foam with an overmolding material.

A device for heating a liquid includes a metal body, a conduit for the passage of the liquid to be heated, and one or more heating elements. The conduit and the one or more heating elements are incorporated in the body which forms a wall around the conduit and the one or more heating elements. Heat generated by the one or more heating elements is transmitted to the liquid to be heated by conduction. The body is provided with a plurality of openings which are separated from each other, having a depth equal to wall thickness. At least two first openings of the plurality of openings are on the conduit, and at least two second openings of the plurality of openings are on the one or more heating elements.
