Abstract
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.
