For the manufacturing of the dies with conformal cooling channels, a layer-laminated manufacturing method and a laser melting process were applied. Extrusion trials with and without applying die cooling were performed. Numerical and experimental investigations revealed that, while maintaining the exit temperature of the extrudate, a distinct increase of the production speed up to 300% can be realized, while the extrusion force increases only slightly. Visioplastic analyses revealed that the rough surfaces, originating from the laser melting, do not disturb the material flow in the welding chamber.",
