Abstract
Procedimiento para la fabricación de cuerpos moldeados huecos, de material fusible, endurecible en una oquedad de molde, cuyo núcleo presenta una membrana deformable, caracterizado porque antes del suministro del material, la membrana se expansiona a un volumen, que rellena la oquedad del molde y porque seguidamente, bajo contracción de la membrana a la forma del núcleo se rellena una cantidad de material endurecible en la oquedad del molde, correspondiente al cuerpo moldeado, que deba fabricarse.
