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 die10and a movable core assembly20which constitutes a disc rotor casting cavity18; a preform supporting portion24awhich is provided on a movable core assembly20; a pressurizing and shaping portion32of an upper die30for applying pressure upon a molten metal accommodated in the cavity18; and a preform biasing mechanism40having a biasing face41bwhich can be brought into a face-to-face contact with the upper face of a preform5which is supported on the preform supporting portion24a. On application of pressure upon the molten metal, the preform biasing mechanism40biases the preform5via the biasing face41bto prevent the preform5from being shifted due to an increase in the pressure upon the molten metal.
