An injection-molding apparatus for article formation. The injection-molding apparatus includes a single mold base supporting at least one grouping of a plurality of shape-forming configuration sets. Each set is shaped for forming one layer of a multilayered article comprising an asymmetric surface. Each set may include at least one cavity which retains each article region formed by the preceding injection-molding shot(s). The single mold base includes an internal movable part which moves within the single mold base with respect to a stationary part such that relative positions of the shape-forming configurations are advanced for each set to form a subsequent article region in the cavities. Each subsequent shot may be prior to full cooling of the article region formed in the previous shot.
An injection-molding apparatus comprising a single mold base supporting at least one grouping of shape-forming configuration sets, each set being shaped for forming one layer of a multilayered article comprising an asymmetric surface with two radial sides, one of the shape-forming configuration sets having a shape of one of the radial sides, at least one other shape-forming configuration set having a shape of the other radial side, the formed article layers being retained in the single mold base at least until completion of the last-formed layer of the article.
A method for article formation, the method comprising the steps of:
