Abstract:
There is provided a preform, and a mold stack for producing the preform. For example, there is provided a preform suitable for subsequent blow-molding. The preform includes a neck portion, a gate portion, and a body portion, extending between said neck portion, and said gate portion. The gate portion, has a conical shape. In an example embodiment, the conical shape is selected such that to homogenize angle of refraction of rays, used during a re-heating stage of a blow-molding process.
