Abstract: A process and apparatus for producing a dry-pressed molding from a particulate or granular molding material such as a ceramic molding composition in which the composition is initially drawn into a loading cavity by applying a vacuum thereto. The loading cavity is formed by a first mold half and a shooting head having a molding surface the shape of which determines the shape of a premolding which is formed upon entry of the composition into the loading cavity and sufficiently compressed to retain its shape after the shooting head has been removed to allow a second mold half to be positioned over the first mold half.

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.
