Abstract (en)

[origin: WO2018229431A1] The method for producing a fine-walled metal part with complex geometry comprises the steps of: mixing (5) a metal powder with a polymer binder in order to obtain a composite mixture, producing (6) a flexible composite sheet from the composite mixture, cutting (7), in the flexible composite sheet, a preform based on a contour of said metal part, applying the preform in a mould having a surface configured with a relief of said metal part, and then debinding and sintering (9) the preform in order to obtain said metal part.
