Process for the continuous extrusion of a structural element by injecting a plastic, extrusion die for implementing this process, and structural element thus obtained

摘要

At least one adjustment member (17) is placed on at least one of the main internal faces (22) of the distribution chamber (3) upstream of the die (4), the adjustment member being able to move with respect to the said face (22). The said member (17) is moved with respect to the said face (22) so as to modify the distribution of the flow of plastic over the surface of the die (4) and to adapt this distribution of plastic, as required, for the production of the said structural element (5). <IMAGE>
