ABSTRACT:
Molding apparatus for producing non-planar parts using compaction molding compounds (CMC) comprises a mold having a cavity which receives CMC therein, the mold including a movable platen assembly having at least two plates movable in substantially parallel directions to compact CMC placed in the cavity, and an actuating mechanism which moves the plates simultaneously at different respective velocities such that the CMC is substantially uniformly compacted into a non-planar shape with a predetermined, substantially uniform density.
