Abstract
In a method of manufacturing a member having a cross-sectional area which varies along its length, the member is produced by filling a cavity 6 in a die 5 with powdered material and compressing it. The die includes portions 8, 9 and 10 at different heights around the opening 7 so as to enable the amount of powdered present in the cavity to be varied along its length without compromising the shape of the final item to be manufactured.
