Abstract (en)
A die unit for radial Conform extrusion machinery has a surface (21) round the entrance to the die (16) which is isolated from any other surface in contact with the material being extruded to the extent that strain induced in that surface by the drag of material entering the die is substantially independent of strain induced in any other surface, said surface having major dimensions from the die orifice to its periphery which differ from one another by no more than +/-25%.
