ABSTRACT:
A method for producing sand cores for foundry, comprising the operations of: defining a molding cavity; blowing in a mixture of sand and hydrated binder into said molding cavity so as to produce a mass of sand, which reproduces in a complementary way the shape of said molding cavity; and producing the passage, through said mass of sand, of a flow of aeriform along at least one principal direction. The method comprises the operation of generating through said mass of sand a flow of aeriform, directed at least in part in a radial direction with respect to said principal direction.
