    Abstract: The present invention relates to a method for the production of cemented carbide based hard metal parts comprising hard constituents in a binder phase by using powder injection moulding or extrusion of a mixture of hard constituents and binder phase in organic binders having a melting point: mixing. The method includes the steps of mixing the powders of hard constituents and binder phase to form a mixture and heating the mixture of hard constituents and binder phase to a temperature. When the temperature of the mixture of hard constituents and binder phase is above the melting point of the organic binders, the organic binders are added in melted form, making sure that the temperature does not fall below the melting point of the organic binders. The parts are formed by powder injection moulding or extrusion. The organic binders are removed from the obtained parts by a debinding step and the parts are sintered.
