An extrusion head (100, 200 and 300) for plastic materials. The extrusion head (100, 200 and 300) is characterized in that a distribution plate (104, 204 and 304) is interchangeable. The distribution plate (104, 204 and 304) includes at least one distribution network (111-116, 211-216 and 311-316) for the extruded materials, so as to determine the characteristics of at least one type of type produced by the extrusion operation through its conformation.
