  • METHOD FOR MANUFACTURING TURBOMACHINE PARTS BY MIM MOLDING
    Publication number: 20220314317
    Abstract: A method for manufacturing an aeronautical part utilizes injection molding. After injecting the prepared mixtures to obtain two green blanks, an assembly area of at least one of these two blanks is heated. The blanks are assembled and then debinding is carried out. A sintering treatment is then carried out.

  • METHOD FOR THE ADDITIVE MANUFACTURE OF A TURBOMACHINE COMPONENT
    Publication number: 20220288692
    Abstract: A method for manufacturing a component, in particular a turbomachine component, in the form of a plurality of superposed layers of a material includes a step of supplying the material into a feed nozzle and a step of projecting energy towards the feed nozzle to cause the material passing through the latter to melt. The method further includes a step of cooling the feed nozzle with a cooling element during the step of projecting energy.

  • ADDITIVE MANUFACTURING METHOD FOR A METAL PART
    Publication number: 20220234107
    Abstract: A method for additive manufacturing deposits material on a part forming a substrate, wherein the part forming a substrate is made of a metal alloy. The method includes a step of low-energy deposition corresponding to a surface energy of less than 400 J/mm2, on a predefined surface to be deposited, in order to form a base layer. The method further includes a step of high-energy deposition, corresponding to a surface energy greater than 500 J/mm2, by depositing a wire on the base layer already formed.
