The invention relates to an injection moulding compounder, comprising an extruder (10), with an extruder housing (12) and at least one extruder screw (14), arranged as to rotate within the extruder housing (12), for the production of melt, an injection device (40), flow-connected, or which may be flow-connected to the outlet from the extruder (10) and a storage device (50) for the buffer storage of melt. According to the invention, the storage device (50) is connected to the extruder housing (12), before the end of the at least one extruder screw (14), in the supply direction of the extruder (10), such that melt produced in the extruder (10) is stored in the storage device (50).

L'invention concerne une machine mélangeuse pour moulage par injection. Cette machine comprend une extrudeuse (10) comportant un carter (12) et au moins une vis d'extrudeuse (14) disposée de façon rotative à l'intérieur du carter (12) pour produire une masse fondue, un dispositif d'injection (40) qui est ou qui peut être en communication fluidique avec la sortie de l'extrudeuse (10), ainsi qu'un dispositif de stockage (50) destiné au stockage intermédiaire de la masse fondue. Selon l'invention, le dispositif de stockage (50) est relié au carter (12) de l'extrudeuse avant la fin de la vis d'extrudeuse (14) dans le sens d'extrusion de l'extrudeuse (10) de telle sorte que la masse fondue formée dans l'extrudeuse (10) soit stockée dans le dispositif de stockage (50).
