ABSTRACT:
A preform and a mold stack for producing the preform. For example, there is provided a preform suitable for subsequent blow-molding. The preform comprises a neck portion; a gate portion; and a body portion extending between said neck portion and said gate portion; the gate portion having a conical shape, wherein the conical shape terminates at a vestige portion having a size that substantially corresponds to the size of an orifice of a hot runner nozzle used in manufacturing the preform. In an example embodiment, the conical shape is selected such that to substantially homogenize angle of refraction of rays used during a re-heating stage of a blow-molding process.
