The method comprises introducing two distinct filling materials (3, 4) in an interior of a container (1). The first filling material has a first thermal effusivity and is made of a metal material, and the second filling material has a second thermal effusivity and is made of sand aggregate, where the first thermal effusivity is higher than the second thermal effusivity. The first filling material is disposed in contact with a first surface (5) of a lost-wax model (2), and the second filling material is disposed in contact with a second surface (6) of the lost-wax model.

The first filling material is disposed in contact with a first surface (5) of a lost-wax model (2), and the second filling material is disposed in contact with a second surface (6) of the lost-wax model. The filling materials have distinct granulometry and density, and form layers that are parallel with one another. The first surface of the lost-wax model has a convex shape.
