Abstract

The lateral extrusion pressing of a partially-heated workpiece (100) gives an axially symmetrical distortion with increased shaping grades. The workpiece (100) is inserted into a lower die (20), to be pressed by an upper die (10) with a press force (F) The local heating is from the lateral extrusion pressing, with the heat effect (30) matched to the shape change behavior of the workpiece (100).
