Method and System for Post-Treating Preforms

A system for the post-treatment of preforms (7) produced in an injection molding mold, comprising at least two post-treatment tools each of which have its own receiving plate (4) which has a group of receiving cavities (2) and its own pin plate (6) which has a group of post-treatment pins (3), and a device for transferring the preforms (7) out of the injection molding mold alternately into the at least two post-treatment tools, wherein the pin plate (6) and the receiving plate (4) of each post-treatment tool are reciprocatingly movable relative to each other between an open position in which the post-treatment pins (3) are arranged outside the receiving cavities (2) and a post-treatment position in which the post-treatment pins (3) are arranged at least partially in the receiving cavities (2).

A method of post-treatment of a preform (7) produced in an injection molding mold, wherein the preform (7) is transferred out of the injection molding mold into a receiving cavity (2) whose internal shape substantially corresponds to the external shape of the preform (7), wherein a post-treatment pin (3) whose external shape substantially corresponds to the internal shape of the preform is introduced into the preform (7) and remains there for a period of time which is longer than the mold stand time of the injection molding mold.
