Abstract
A method for the fabrication of a plastic preform suitable for use in the preparation of biaxially oriented hollow articles is described wherein the duration of the preform injection molding cycle is reduced, thereby enhancing the productivity of the injection molding step. This end is attained by injection molding and cooling, and supercooling and conditioning simultaneously at a single station of an injection molding machine at different positions within the station.
