Abstract (en)
[origin: WO2010059116A1] 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.
