The invention relates to an extrusion die for an extrusion tool for producing composite profiled elements from different materials that are processed at different temperatures, comprising separated channels (8, 9, 10, 22) in a die body (1 to 6), wherein said channels open at the end face (15) of the extrusion die and different materials are conveyed through said channels. At least one channel (9, 10) is formed by a nozzle (12) accommodated in the die body (1 to 6) in such a way that the nozzle can be replaced. The nozzle has a temperature-control device. |
