摘要:
A method for the production of tungsten carbide based cemented carbide or cermet tools or components using the powder injection molding method includes mixing of hard constituent powder and a metallic binder powder with an organic binder system, consisting of 30-60 wt-% olefinic polymers and 40-70 wt-% nonpolar waxes, acting as a carrier for the powder. A metallic binder powder that is granulated with a nonpolar wax is used.
