Tube B ending, Hydroforming & End-Fo rming
138 May/June 2007
Fenn Technologies, USA, manufacture a
range of rotary swaging machines in all
sizes, from the NF 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.
For forming continuous tapers in tube up to
610mm in length, the company offers long
die swagers for use in the furniture and
sports equipment fields. These long die
swagers are also used by high performance
bike manufacturers to swage titanium tube
for forming precise taper angles on frames.
Refrigeration and appliance manufacturers
swage copper tubing to form filters with
dome reduced ends. The company’s
swagers are also utilised for critical
operations in the aerospace and defence
industries, together with the jewelry
and musical instrument trade. Other
applications that take advantage of Fenn
swaging technology are heater elements
and thermocouples (to reduce stainless
tube filled with MGO).
