The invention relates to a method for producing a strand-shaped part, wherein a hollow section (16) of metal is extruded, the extruded metal hollow section (16) cools and/or is cooled, and a plastic strand (28) having one or more layers is extruded into the extruded metal hollow section (16) after or during cooling. The plastic strand (28) passes by a dispensing tool (24), exposed to the heat of the extruded metal hollow section (16) of an extruder (34). The dispensing tool is inserted into the metal hollow section (16) and comprises a dispensing outlet (26), which is disposed inside a region of the metal hollow section (16) in which the dispensing tool is cooled in relation to the temperature thereof during extrusion.
