The difference between diameters of die-hole and of sunk tube is due to a plastic deformation of the tube which occurs after it has left completely the wall of dies. This plastic deformation is analysed theoretically under several assumptions. As a result, the difference between the diameters can be computed by using the values determined by sinking conditions and the mechanical properties of the sunk tube materials. The fillet radius of dies has a conspicuous influence on the plastic deformation of tubes and the ratio of the radius to the thickness of tubes should be larger than 10 to keep the difference between the diameters least. Experiments are carried out on steel tubes. The results agree well with the analysis.
