Abstract

Un método y un aparato para el moldeo de una pieza desde una masa de materia prima permeable al gas en un molde (14) permeable al gas. El molde se coloca en una cámara (19) de flujo de tal manera que el gas que fluye a través de la cámara de flujo también se haga fluir a través del molde. Una cámara (16, 18) del material de relleno, permeable al gas, llena con este material de relleno (26), se coloca en la parte frontal y/o detrás del molde, esta cámara de relleno conduce a la caída de presión deseada, por ejemplo de la misma magnitud, sobre el 'paquete' (12), formado por el molde y la cámara de relleno, a lo largo de toda el área en sección transversal de la cámara de flujo. La invención también se refiere al producto producido por éste método.
