Abstract
In carrying out a cast-in process, a cast-in insert member is placed into a cast forming cavity in a casting mold, and a casting is conducted. The cast-in insert member has a barrier layer on its non-deposited surface for inhibiting the deposition of a molten metal. During casting, a portion of a molten metal is introduced to a heating chamber on the side of the barrier layer to come into contact with the barrier layer. Thus, the cast-in insert member can be heated not only from the side of its deposited surface, but also from the side of its non-deposited surface, thereby providing an enhanced strength of deposition of the cast-in insert member.
