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.

Abstract: The present invention relates to a method for the production of tungsten carbide based cemented carbide or cermet tools or components using the powder injection moulding or extrusion method comprising mixing of granulated cemented carbide or cermet powder with an organic binder system whereby the mixing is made by adding all the constituents into a mixer heated to a temperature above the melting temperature of the organic binders. According to the invention the organic binders are added into the mixer, waiting for a melt to form and then slowly adding the cemented carbide or cermet powder into the melt, making sure the temperature does not fall below the melting temperatures of the organic binders.
