Abstract
The extrusion device of a solid film comprises a cell provided with an input opening of a material designed to form the solid film, and an output opening of the solid film from the cell. The device comprises a first heat exchanger for applying a first temperature to the output opening and a second heat exchanger for applying a second temperature in a first zone of the cell distinct from the output opening and a control circuit imposing first and second sets of first and second temperatures. The first set enables a volume of the material in solid phase to be formed. The second set enables a temperature gradient to be generated in the volume so as to generate a pressure forcing extrusion of the solid film via the output opening.
