Abstract
A compression mold apparatus for compressing a segment has a base having an elongated and substantially semi-circular mold cavity and an end plate including a blade mounted thereon. The mold cavity has a top opening. A ram is aligned with the top opening. The ram includes two fixed opposing planar flank surfaces. The two fixed opposing planar flank surfaces are nominally centrally separated by a ram groove for mating with the blade while allowing linear movement within the mold cavity. A ram press is connected to the ram for translating the ram linearly along the blade within the mold cavity. A plurality of cartridge heaters is mounted in the base and arranged around the mold cavity for heating the segment.
