ABSTRACT:
A stamped, steel insert for use in metal die cast articles. The insert includes first and second interconnected stamped steel insert halves spaced from one another at certain locations to define a void. Openings communicating with the void extend through each insert half to facilitate material flow and to improve interlock of the insert and die cast material. The edges of the insert lie below the surface of the casting to avoid bimetallic machining. The insert halves cooperate to define a pair of elongated passages, which are bored following die casting to form fastener holes. At least one of the passages has an elongated cross section to allow for expansion and contraction of the insert during casting.
