Mandrel Bending Components
When bending thin wall tube it may be necessary to insert a
mandrel into the tube to prevent excessive distortion or flat-
tening.To accomplish such bending, a Mandrel, Mandrel Rod,
and aMandrel Rod Stop Assembly are required.The Rod Stop
Assembly holds the end of the Mandrel Rod in proper align-
ment with the tube while the Mandrel, which is threaded onto
the other end of the Mandel Rod, supports the tube on its I.D.,
thus preventing tube kinking or flattening during bending.
