Abstract

The object of the present invention is a casting method for obtaining a casting in a metal material, comprising the manufacture of a model of the casting in a material adapted for dissolving in contact with the molten metal material, the laying of said coated model with the pouring gate in a container packed with sand and adapted for receiving the molten metal material, the casting of the molten metal material in said container so that said metal material dissolves the material forming the gate casting model replacing it, wherein during the moulding or prior to the coating, at least one insert in a material resistant to the heat of the molten metal material in incorporated into said model, so that said at least one insert is incorporated in the casting at the end of the casting step.
