Title (EN) MICRO-EXTRUSION LINE
(FR) MICRO-LIGNE D'EXTRUSION
Abstract: front page image
(EN)The invention refers to a micro-extrusion line that comprises a single screw (2) micro-extruder (1), a die (7), a cooling bath (17) and a haul-off (19), which together enables the manufacture of extruded profiles from small amounts of raw material. The rotation of the micro-extruder screw, together with the high temperatures created by the heater bands, produces the conveying, melting, mixing and pumping of the material through the die. The extrudate is cooled down in a bath containing a cooling liquid and winded in a coil (19), which has a linear speed higher than that of the extrusion, thus enabling the control of the extrudate cross-section.
(FR)L'invention concerne une micro-ligne d'extrusion comportant une micro-extrudeuse (1) monovis (2), une filière (7), un bain de refroidissement (17) et un dispositif de tirage (19), lesquels permettent ensemble la fabrication de profilés extrudés à partir de petites quantités de matière première. La rotation de la vis de la micro-extrudeuse, conjointement avec les températures élevées engendrées par les bandes chauffantes, provoque le convoyage, la fusion, le mélangeage et le pompage de la matière à travers la filière. L'extrudat est refroidi dans un bain contenant un liquide réfrigérant, et enroulé en une couronne (19), laquelle présente une vitesse linéaire supérieure à celle de l'extrusion, permettant ainsi le réglage de la section de l'extrudat.
