Abstract
A temperature control device (10) for a plasticising screw (1′) and/or a plasticising cylinder (1″) of a plasticising unit is presented. The plasticising screw (1′) and/or the plasticising cylinder (1′) is formed from a hollow cylinder (11), in the central longitudinal cavity (110) of which the temperature control device (10) for controlling the temperature of the plasticising screw (1′) and/or of the plasticising cylinder (1″) is accommodated. The temperature control device (10) is characterised in that it (10) is in the form of an inner cylinder (100) which is designed to be accommodated in the hollow cylinder (11), and on the outer lateral surface (1000) of which at least one flat heating element (101) is arranged or applied.
