    Abstract: A method and system of injection molding a plastic item, such as a preform, is provided. The method and system relates to positioning a first core within a mold cavity such that a first space is defined between the inner surface of the mold cavity and the outer surface of the first core and injecting a flowable first plastic material into the first space to form a first preform layer. The method and system relate to positioning a second core within the mold cavity and within the first preform layer such that a second space is defined between the inner surface of the first preform layer and the outer surface of the second core and injecting a flowable second plastic material into the second space to form a second preform layer located inside the first preform layer.
