ABSTRACT:
An article, such as a card of thermoplastic material containing vials, is molded by a method and apparatus which deforms a portion of the mold flash so as to form a reference surface. In a preferred embodiment, the article has a pair of lower walls extending from a central wall in a generally inverted V-shape configuration diverging from an apex which defines a downwardly facing reference surface from which a predetermined reference position can be established for subsequent operations. A conveyor belt can be employed to engage the reference surface and support the article at the reference position.
