A molded article can be formed from a molding material using a molding system. Various molded articles can be formed by using a molding process such as an injection molding process. One example of a molded article that can be formed from, for example, polyethylene terephthalate (PET) material is a preform that can be subsequently blown into a beverage container such as a bottle.

When cooled, the molded articles shrink within the mold cavities, such that the molded articles tend to remain associated with the core pieces as the cavity plate is forced apart from the core plate. Thus, by forcing the core plate apart from the cavity plate, the molded article can be demolded, i.e., ejected from the core piece. Ejection structures are known to assist in removing the molded articles from the core halves. Examples of ejection structures include stripper plates, ejector pins, and the like.
