摘要： 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.

摘要： In the production of molded articles from a pourable compound, such as an oxide ceramic compound, for example, a porcelain compound, an injection chamber is formed between an isostatic compression molding tool and a superposed injection head, negative pressure conditions are established within the injection chamber. The pourable compound is fluidized and is drawn into the injection chamber by the negative pressure. Subsequently, the compound is isostatically compressed while the negative pressure conditions are maintained during at least the initial phase of the compressing operation. A closing member is positioned at the opening into the injection chamber through which the pourable compound flows. The closing member is displaceable between an open position admitting flow and a closed position blocking flow into the injection chamber. In the closed position, the surface of the closing member facing into the injection chamber forms a continuation of the adjacent surface of the injection chamber.

摘要： Particularly large-size bell and spigot pipes of ceramic molding material are isostatically pressed within a hollow-cylindrical pressure pot with a molding cavity for the molding compound. An inner core is axially extractable and an elastomeric diaphragm is disposed concentrically around the inner core. The diaphragm is clamped in place at its end face and there is defined between the pressure pot and the diaphragm a chamber which communicates with a source of hydraulic pressure. The inner core is provided with a molding ring on which the bell region of the bell and spigot pipe is formed. The molding ring has a reduced-diameter end region and thus defines two end faces. The two end faces are concentric but axially spaced apart. At least the upper end face of the molding ring is provided with a surface coating of elastic plastic material. An annular gap is defined between the end region of the molding ring and the inner core which, depending on the hydraulic pressure in the cavity, opens and closes a vent port which communicates with the molding cavity. Microcracks in the bell region of the molding can be safely avoided.

摘要： According to one example of embodiment of the invention a ceramic pre-moulding 81 of stable form is pressed from ceramic composition in powder form in a first isostatic pressing action, at least a part of its surface being formed in contact with rigid shaping surfaces 42. The pre-moulding 81 thus obtained is then--possibly after glazing-subjected to a higher pressure, in a further pressing operation on all sides and then fired in a ONCE-ONLY quick-firing method.
