Abstract: The present invention concerns a system for the further treatment of hollow body preforms produced by injection molding, comprising i) a receiving plate having at least one receiving cavity for receiving a preform, ii) a post-treatment system which has a) a post-treatment plate, b) at least one impression pin provided for changing the internal contour of the profile by either coming into contact with the inside of the preform during the post-treatment or closing the preform and acting on the inside space with a fluid under pressure, whereby the preform is inflated, and c) at least one post-treatment element which is provided for passing into the interior of a preform received in the receiving cavity or coming into contact with the preform, and iii) a movement device with which the receiving plate can be reciprocated relative to the post-treatment plate between a first position in which the impression pin is positioned within the receiving cavity, a second position in which the post-treatment element is pos

Abstract: A cooling system for cooling sleeves (2) fixed to a carrier plate (1), by means of a fluid which is passed from a fluid inlet (15) to a fluid outlet (22) by way of fluid conduits (7, 14, 10, 11, 21) supported by means of the carrier plate (1). The fluid conduits (7, 14, 10, 11, 21) include main supply conduits (7) and supply conduits (10, 11) which extend approximately transversely with respect to each other. The supply conduits extend in a mutually parallel relationship and are arranged in pairs in the carrier plate (1) and are connected to a row of sleeves (2) by way of intake (16) and discharge conduits (17). The row of sleeves (2) is so disposed between the supply conduits (10, 11) of a pair such that each sleeve (2) is connected to both supply conduits (10, 11), and fluid communication is interrupted (plug 24) in at least the one supply conduit (10) of the pair substantially at the middle of its longitudinal extent (l).
