Device for manufacturing metal objects

A device for producing copper or copper-based metal objects in a continuously operated extrusion device, the device comprised of an extrusion member and a rotatable feed member that is essentially wheel-shaped and has a groove formed on the circumference thereof, where the material to be extruded is brought to the extrusion member in said groove, the groove, being essentially U-shaped and defined by two side walls that are connected by a curved wall part constituting the bottom of said groove, the walls being coated with a metal coating or non-metallic coating, the coating essentially adhering well with copper or copper-based material processed in the device, but not being said copper or copper-based material processed in the device, the ratio of the groove width to the groove height being within the range 1.0-1.5, measured at the widest and highest spots of the groove.
