Abstract: An improved device, system, and method to produce a molded component with an undercut includes an insert comprised of a plurality of separate pieces individually removable from the molded component. The pieces are arranged and functionally interlocked in an assembled configuration. Removal of a post member or piece from the insert creates a cavity within the same. Thereafter, one or more of the pieces is slidable, movable, or collapsible into the cavity and subsequently removed from the molded component. The remaining pieces are movable, often sequentially and iteratively, into the cavity and subsequently removed. Each of the pieces can have a different geometry. A plurality of the inserts can arranged into an array and connected to a bottom tool structure. The array of inserts can be configured to produce a molded component have a plurality of cells arranged in a matrix, such as a airflow diverter duct.

Abstract: A multi-piece mold for use in a method for making a slurry distributor includes a plurality of mold segments 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 has a maximum cross-sectional area in a plane substantially transverse to a direction of movement of the mold segment along a removal path 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.

Abstract: A polymer is formed into the shape of a one-piece composite part and then solidified by curing, setting, hardening or otherwise solidifying the polymer to form a shaped polymer form having a shape that does not draw. Composite material is laid lip on the form and solidified to from the composite part. The rigidity required of the form to lay up the composite part can be provided by operating in the polymer form's glassy state, forming the shaped polymer form with a hollow core and placing a rigid insert designed to draw inside the hollow core with the polymer form in its elastomeric state or through a combination of both. In its elastomeric state the form becomes pliable (without relaxing to a different memorized shape) and can be drawn out of the one-piece composite part. Because the shape of the form does not draw, the form deforms as it is drawn. If used, the rigid insert is drawn out prior to removing the shaped polymer form. Upon removal, the polymer form in its elastomeric state returns to its original shape. The form may be used once and thrown away or reused to form multiple composite parts of the same shape.
