1. Support tooling for supporting at least one metal part that is to be subjected to heat treatment or shaped while hot, said tooling comprising:

  • a stationary support structure presenting a determined shape that corresponds to the general shape of each metal part that is to be supported;

    first holder elements arranged along and against one side of each metal part that is to be supported;

    second holder elements arranged along and against the other side of each metal part that is to be supported, the one side of the metal part being opposite the other side of the metal part; and

    at least one spring type resilient element placed between the support structure and each first holder element or between the support structure and each second holder element so as to exert a resilient holding force on each first holder element and on the metal part or on each second holder element and on the metal part to hold the metal part throughout the duration of heat treatment;

    the support structure, the first and second holder elements and the at least one spring type resilient element being made of thermostructural composite material,wherein the support tooling includes a plurality of pairs of jaws placed on either side of the metal part, each jaw being slidably mounted on the support structure so that the jaw is slidable along a longitudinal direction of the support structure to accompany a movement of the metal part along the longitudinal direction during the heat treatment, the longitudinal direction being different from a direction along which the resilient holding force is exerted.
