1. A support frame for a sintering step of a method for producing a part, in particular for watchmaking, from a green body having an initial shape having a shape in relief, the body shrinking from the initial shape to a final shape during the sintering step, the support frame comprising:
at least one face for supporting the body during the sintering step, wherein the geometry of the supporting face is in relief and configured to support the body from its initial shape into its final shape, so that it retains its shape and proportions in line with a shrinkage coefficient related to the sintering operation,
wherein the supporting face comprises a central part and two side parts extending outward from the central part, the central part being raised in relation to the two side parts, and a distal end of a first of the side parts is raised in relation to a distal end of a second of the two side parts.
