Thin Wall Tube Bending with Mandrel Equipment
Instructions for Thin Wall Tube Bending with Mandrel Equipment
When bending thin wall tube it may be necessary to insert a
mandrel into the tube to prevent excessive distortion or flatten-
ing. To accomplish such bending, a Mandrel, Mandrel Rod, and
a Mandrel Rod Stop Assembly are required. The Rod Stop
Assembly holds the end of the Mandrel Rod in proper alignment
with the tube while the Mandrel, which is threaded onto the other
end of the Mandrel Rod, supports the tube on its I.D., thus
preventing tube kinking or flattening during bending.
