Method for compacting powder material

A method for compacting a powder material comprising ceramic powder;

• the method comprises at least a first compacting step, during which the powder material is compacted, at a work station, so as to obtain a layer of compacted powder material and a pressure device, having a structured contact surface, comes into contact with the powder material so that the layer of compacted powder material has a structured surface;
• and a conveying step, during which the powder material is conveyed, along a first segment of a given path, to the work station and the layer of compacted powder material (KP) is conveyed from the work station along a second segment of the given path;
• the pressure device comprises at least a first layer and a superficial layer arranged so as to at least partially cover the first layer relative to the outside;
• during the first compacting step, the superficial layer comes into contact with the powder material and at least part of the superficial layer wears so as to uncover at least part of the first layer and obtain at least areas of the first outwardly exposed layer;
• the method comprising at least a first hardening step, which is at least partially simultaneous to and/or subsequent to the first compacting step and during which the areas of the first outwardly exposed layer are hardened.
