An apparatus for molding a plurality of containers being interconnected with linking arms. The apparatus includes a first member and a manifold member, operatively attached to the first member, for channeling a plastic fluid to an insert. The insert contains a first slide and a second slide. The first slide and second slide will have an extended position and a contracted position, and wherein the contracted position defines a plurality of interconnected cavity profiles. The second member will have a first end that contains a plurality of core pins. A piston is adapted to the second member for reciprocating the second member into engagement with the insert so that the first slide and second slide are moved to the contracted position. During the reciprocating motion, the plurality of core pins are received in the cavity profiles. The apparatus will further comprise a heater for supplying a heat to the fluidized plastic. Also described herewith is a method of casting a container with a mold, with the container being used as a medical vial.
