Fenn Technologies, USA, manufacture a range of rotary swaging machines in all sizes, from the IMF series for the medical industry, to the massive model 8F for reducing high strength steels and alloys for up to 153mm diameter tube. The powerful model 8F swagers can reduce thick wall tubing so that the outer diameter can fit into its inner diameter, thus forming continuous tubing for railing or street light poles. The company also manufactures hydroformer (die closing) rotary swagers that are used widely in the aircraft and marine industries. Hydroformers can undertake centre reductions on tubes to form ornamental designs and architectural shapes. In addition, Fenn's stationary die swagers can form irregular shapes for the commercial tool industry and speciality tube.
