Servo side shuttle apparatus and method for a molding machine includes structure and/or steps whereby a shuttle plate is disposed adjacent at least one of a first mold half and a second mold half of the molding machine. A guidance assembly is coupled to the mold half and guides the shuttle plate linearly across a molding face of the mold half. A drive mechanism is provided to drive the shuttle plate in a linear direction. An operation structure is coupled to the shuttle plate and is configured to perform an operation on a molded article disposed either in the mold cavity or on the mold core. The operation may include removing the molded article from a mold core, applying a label to a mold cavity, and/or closing the lid of a molded article while it is resident on the mold core.
