A method for the manufacture of a moulding composition from a raw material melt which is charged with an additive includes the steps: charging a conveyor apparatus (4) with a raw material which includes a liquid or gooey pasty composition or a granulate, with the conveyor apparatus in particular including a cylinder (5) in whose interior space a conveyor means, in particular a screw (6) is arranged; converting the raw material into a raw material melt by heat supply to the raw material, in particular via a heating apparatus which is in particular arranged at the outer wall of the cylinder 5; charging the raw material melt with an additive; mixing of the raw material melt with the additive to produce a moulding composition, with the moulding composition being present as a homogeneous mixture the raw material melt with the additive; discharge out of the moulding composition from the conveyor apparatus. The charging of the raw material melt with the additive takes place in a metering device (3) which is arranged in a passage section (29, 30) of the conveyor apparatus (4) and/or subsequent to the conveyor apparatus (4), with the raw material melt (29, 30) flowing through and/or around the passage section. The metering device includes at least one metering element (31) which is arranged ina recess (32) of the passage section (29, 30). Fig. 1 |
