Abstract
A sand core body, constituted by two similar parts intended to be coupled together to form at least a portion of a full sand core, in which the sand comprising said part is densified in all its extension, except in the peripheral areas thereof, the sand of said peripheral areas being relatively non-densified beyond the possible joining line of the parts, in which a part of the core destined to be coupled in said peripheral zones originates, with a part similar, by the application of a pressure that forces said non-densified zones toward each other.
