Abstract

The hollow body production process involves forming a conical region in the workpiece (10) (a hollow shaft), linking a larger-diameter sector (14) to a smaller-diameter sector (16). The conical region (12) specifically is heated. An axial upsetting force is then applied so that the conical region is upset to form a step (20).
