METHOD OF DIE CASTING A REDUCIBLE CORE UNIT ABSTRACT OF THE DISCLOSURE A die-cast core is formed by fabricating a die defining a cavity in which the core is formed, and injecting under pressure a reducible material in a molten state into the cavity of the die, thereby die casting the core. A preformed liner may be placed in the cavity of the die prior to the injection of the molten reducible material, so that after the injection, the liner is provided with a reducible die-cast core. The die-cast core can be used in fabricating various machine parts, such as a cylinder block for an internal combustion engine.
