Abstract
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, the body shrinking from the initial shape to a final shape during the sintering step, the support frame having 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. The disclosure further relates to a sintering method using this support frame.
