Abstract
A device for producing ceramic mouldings is disclosed comprising an isostatic press-mould half having an isostatic pressure membrane and an injection head having an inlet opening for introducing granulate and an extraction orifice for sucking the granulate in or out of the mould cavity. The injection head is spring-mounted on a press crosspiece which supports it, so that, as the injection head moves towards the isostatic press-mould half, a sealing pressure slowly forms between the injection head and the isostatic press-mould half and as the injection head moves away from the isostatic press-mould half this sealing pressure is slowly reduced.
