A system for manufacturing metal matrix composites, each including a porous preform infiltrated with molten metal, includes a programmable, automated arrangement for handling preforms for sequential introduction into a die caster of the system. A preform loader includes a reciprocable loading head which receives each preform from an associated stack, and delivers each preform to a horizontally reciprocable carrier of a preform shuttle. The preform shuttle effects indexed movement of each preform along a substantially horizontal path, through a preheating furnace, and into the die caster. Efficient operation of the system is promoted, while undesirable damage to the relatively brittle porous preforms is avoided.

[ What is claimed is:] [1.] A system for manufacturing metal matrix composites each comprising a preform infiltrated with metal, comprising:a die caster having upper and lower dies defining a die cavity therebetween, said upper and lower dies being relatively movable between an open position for receiving a preform, and a closed position for infiltrating the preform with molten metal; anda preform shuttle supporting a preform canier movable in a substantially horizontal path, said preform carrier being configured to receive a preform thereon, said preform carrier defining an opening within which the preform is carried, said carrier including at least one movable finger positioned beneath said opening to support the preform therein, said movable finger being movable to release the preform from within said opening, said shuttle being operable to move said carrier and the preform thereon to a position between said upper and lower dies of said die caster so that upon release of said preform the preform moves by gravity onto the lower die of said die caster and positions the preform in said die cavity for infiltration with molten metal upon removal of said carrier from said position between said upper and lower dies by said shuttle.
