ABSTRACT:
A mold assembly includes first and second housings having generally curved surfaces inside the mold cavity. The first housing has apertures extending therethrough. The second housing may have apertures, axially aligned with the apertures of the first housing, extending partially or completely therethrough. At least one guided, flexible, elongated rod member is configured for reception in the apertures of the first and second housings, the rod members being movable in a direction non-parallel to a direction of movement of the mold assembly with respect to the rod members. The mold-assembly is particularly useful for forming a molded body having a plurality of apertures, aligned in arbitrary non-parallel directions relative to one another, extending therethrough.
