Moulding tool and method for powder injection moulding a cemented carbide or cermet component
A moulding tool for powder injection moulding a cemented carbide or cermet component includes a through hole. The moulding tool further includes at least a first and a second tool part arranged to define at least one mould cavity for forming a component. At least one inlet channel introduces moulding material into the mould cavity. The inlet channel extends through the first tool part to the mould cavity, and has an outlet end having an outlet opening for discharging moulding material from the inlet channel into the mould cavity. At least one core forms a through hole in the component, the core having an end and being arranged to extend into the mould cavity along a longitudinal axis (X) in a direction towards the outlet opening of the inlet channel. The end of the core is arranged to close the outlet opening of the inlet channel and the core is arranged movably along the longitudinal axis (X) such that the end of the core may engage with the outlet opening of the inlet channel.
