An isostatic die for tile forming comprising a metal body ( 2 ) and an elastically deformable membrane ( 6, 6', 6'' ) which is solidly gripped to the metal body ( 2 ) in a plurality of distinct predetermined fixing zones ( 25, 28, 290, 21, 22, 24', 24'' ), such that an intermediate hermetically sealed chamber is delimited between the elastic membrane ( 6, 6', 6'' ) and the metal body ( 2 ), which chamber is destined to contain an incompressible fluid. Rigid bushings ( 5, 5'' ) are sunk into the elastic membrane ( 6, 6', 6'' ), each of which rigid bushings ( 5, 5'' ) is located at a fixing zone ( 25, 28, 290, 21, 22, 24', 24'' ) of the elastic membrane ( 6, 6', 6'' ) to the metal body ( 2 ), and defines a breather mouth lo ( 52 ) which passes into a body of the elastic membrane ( 6, 6', 6'' ) and which communicates with an outside environment through a system of discharge conduits ( 9 ) afforded in the metal body ( 2 ), each rigid bushing ( 5, 5'' ) receiving a respective obturator body ( 7 ), which obturator body ( 7 ) enables passage of air and at least partially prevents passage of ceramic powder.
