DISPOSITIF ET PROCEDE D'EXTRUSION D'UN CORPS SOLIDE

摘要

The device (1) has a cell (2) with an input opening (3) and an output opening (4). A heat exchanger (E1) applies a temperature (T1) to the output opening, and another heat exchanger (E2) applies another temperature (T2) in a zone (6) of the cell. A control circuit controls the exchangers to impose a set of temperatures to form a volume (V1) of the material in solid phase inside the cell, and another set of temperatures to generate a temperature gradient between the output opening and the zone so as to generate a pressure in the cell forcing extrusion of the solid film via the output opening. An independent claim is also included for a method for extrusion of a solid film.
