ABSTRACT:
An apparatus and method are provided for molding sterile parts. The apparatus has a first mold portion and a second mold portion. At least one of the first and second mold portions defines a mold cavity configured to receive a molten plastic and form therefrom at least one molded part At least one of the first and second mold portions is movable relative to the other between (i) a closed position for sealing the mold cavity or cavities and molding at least one part therein, and (ii) an open position defining a fluid passageway between the first and second mold portions and permitting the passage of a fluid sterilant therein. A fluid source that contains or otherwise generates a fluid sterilant, such as vaporized hydrogen peroxide, is connectable in fluid communication with the fluid passageway for introducing the sterilant into the fluid passageway with at least one of the first and second mold portions in the open position, and in turn contacting with the sterilant the surfaces of the first and second mold portions forming the fluid passageway and located adjacent to the at least one mold cavity, but not contacting an interior surface of a molded part within the mold cavity, to sterilize the exposed mold surfaces and thereby prevent contamination of the molded part.
