摘要
A process for manufacturing a salt core to be introduced into a foundry mold by casting of parts made of aluminum, aluminum alloy, or light alloys obtained according to casting operations in order to form a foundry preform. The core is a salt powder and undergoes for its shaping an isostatic compression of the salt powder. The core obtained with the desired shapes is then introduced into the foundry mold to make the form to be obtained, and the shape resulting from the foundry operation is a preform including the salt powder core obtained by isostatic compression. The preform is then forged with its core at a pressure ranging between 600 and 700 MPa to obtain the final form of the product to be obtained, and the core subsequently removed.
