Abstract
An apparatus and process for manufacturing a disc rotor made of a metal-based composite material, which enables stabilization of a preform support within a disc rotor casting cavity while minimizing likelihood of damaging of preforms. The apparatus comprises a lower dieand a movable core assemblywhich constitutes a disc rotor casting cavity; a preform supporting portionwhich is provided on a movable core assembly; a pressurizing and shaping portionof an upper diefor applying pressure upon a molten metal accommodated in the cavity; and a preform biasing mechanismhaving a biasing facewhich can be brought into a face-to-face contact with the upper face of a preformwhich is supported on the preform supporting portion. On application of pressure upon the molten metal, the preform biasing mechanismbiases the preformvia the biasing faceto prevent the preformfrom being shifted due to an increase in the pressure upon the molten metal.
