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 includes at least one cavity and is shaped for forming one of first-formed, intermediate-formed and last-formed regions of the article in the cavities by a corresponding one of injection-molding shots. Each cavity retains each article region formed by the preceding injection-molding shot(s). The single mold base includes a movable part which moves internally 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 injection-molding shot may at least partially over-mold the article region formed in the preceding shot. Each subsequent shot may be prior to full cooling of the article region formed in the previous shot.
An injection-molding apparatus for article formation, the apparatus comprising a single mold base supporting at least one grouping of a plurality of shape-forming configuration sets each shaped for forming one of first-formed, intermediate-formed and last-formed regions of the article, the formed article regions being retained in the single mold base at least until completion of the last-formed region.
An injection-molding apparatus for article formation, the apparatus comprising a single mold base supporting a plurality of groupings each of a plurality of shape-forming configuration sets for simultaneous formation of first-formed, at least one intermediate-formed and last-formed article regions each for one of a plurality of the articles.
A method for article formation, the method comprising the steps of:
