Abstract: Compression mold assembly for forming a preform of a cascade includes first and second die elements and an axis of alignment. Line of removal of a formed preform is positioned perpendicular to a plane perpendicular to the axis of alignment. First die portion includes first curved surface forming interior surface of first strong back and second die portion includes first curved surface forming interior surface of a second strong back of a cell of a formed preform. Second die portion includes second curved surface forming an interior surface of a first vane on forward side of the cell of the formed preform and first die portion further includes first wall member which extends along line of removal and a second wall member which extends angularly from first wall portion forming an interior surface of a second vane positioned on an aft side of the cell.
