Abstract: A method of sintering a metal injection-moulded, green aerofoil component. The method includes providing a setter having a stationary support arranged to support an aerofoil part of the component and a moveable platform arranged to support an end part of the component, the moveable platform being independently moveable relative to the stationary support. The method further includes locating the green component on the setter such that the aerofoil part and the end part are supported by respectively the stationary support and the moveable platform. The supported green component is then sintered, the moveable platform moving during the sintering relative to the stationary support to accommodate sintering-induced shrinkage of the component.
