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 positioned within the receiving cavity or comes into contact with a preform received therein, and a third position in which neither the impression pin nor the post-treatment element is positioned within the receiving cavity or comes into contact with a preform received therein.

An apparatus (100) for the continuous cycle production of containers from plastic material comprises a metering unit (1) configured to receive from an extruder a flow of molten plastic and to produce a plurality of doses simultaneously from the flow of molten plastic; a forming station (2) includes a plurality of female compression elements (3) for simultaneously receiving the plurality of doses from the plurality of outlets of the metering unit; a plurality of male elements (4) acts in conjunction with the female compression elements (3) to make a plurality of parisons simultaneously by compression moulding; a blow moulding station (5) is configured to receive the parisons of the plurality of parisons and to blow mould the plurality of parisons to form a corresponding plurality of containers.
