Document Type and Number:
WIPO Patent Application WO/2013/063080
Kind Code:
A3
Abstract:
A multi-piece mold for use in a method for making. a slurry distributor includes a plurality of mold segments (551,552,553,554,555) adapted to be removably secured together. The mold segments are configured such that, when the mold segments are assembled together, the assembled mold segments define a substantially continuous exterior surface adapted to be a negative image of an interior flow region of a slurry distributor molded thereupon- Each mold segment (551,552,553,554,555) has a maximum cross-sectional area in a plane substantially transverse to a direction of movement of the mold segment along a removal path (581, 582, 583, 584, 585) out of a respective opening of the molded slurry distributor. The maximum cross-sectional area of each mold segment is up to about 150% of the smallest area of the interior flow region of the molded slurry distributor through which the mold segment traverses when moving along the respective removal path (581, 582, 583, 584, 585).
