Large metallic shells (35), suitable for use as molds, are fabricated by plasma or arc spraying using a thermal spray gun (22) to spray molten metal onto a matrix (10) to deposit a shell metal layer (37) with a cavity (35). The completed metal mold (37) may be used to form composite articles (41).

De grandes coques métalliques (35), appropriées pour servir de moules, sont fabriquées par projection plasma ou métallisation à l'arc au moyen d'un pistolet (22) pour projection thermique afin de pulvériser du métal fondu sur une matrice (10) et déposer une couche métallique (37) pour former une coque constituée d'une cavité (35). Le moule métallique (37) terminé peut être utilisé pour former des articles composites.
