Abstract

Son premier étage est constitué par une extrudeuse à deux vis à double alimentation avec sens opposés d'extrusion. L'accouplement entre le premier et le second étage s'effectue, de préférence de bas en haut en rapport direct Une telle extrudeuse permet de traiter n'importe quelle sorte de matière thermoplastique et d'obtenir en particulier un dégazage parfait, avec la possibilité de contrôler et de faire varier à volonté l'état physique de la matière ou du mélange à extruder, au niveau de zone de dégazage.
