ABSTRACT:
A molding apparatus includes stops which move with a compacting press during penetration of the press into a mold cavity. The stops abut on a mold table and arrest movement of the compacting press so that the compacted shape has a predetermined height. A programmed logic controller integrated with the apparatus measures the time of compaction and is operable to adjust mold filling time so as to control density in the final compacted shape.
