Abstract
A method of manufacturing a component from metal-containing powder. A paste is prepared by mixing at least a powder comprising metal, a binder in an amount of 2 to 8 weight % of the paste, and liquid, such as water, in an amount of 5 to 25 weight % of the paste. The paste is transferred to an extruder, and the paste is extruded into a green body by using an extrusion pressure (P) of more than 50 bar. Then the green body is dried and sintered or oxidized to obtain the final component.
