For producing a dome-shaped element (2) provided with thermal protection for a solid propellant rocket engine, a coupling annular body (4) is arranged in a mold (5) and has a surface (20) that is clean and activated, by an atmospheric-pressure plasma treatment, before depositing a primer layer (26) and an adhesive layer (27) on the surface (20); ablative material is then automatically applied to the adhesive layer and to an area (17) of the mold (5) so as to form a series of superimposed layers (30).
