Features of Four Roller Bending Machine:
1. This machine has a better ability to produce barrel with smaller diameters than ones produced by other machines of the same standard. Moreover, it is energy-saving, it consumes less electricity than most of our competitors' machines.  
2. Two kinds of rolling available: Asymmetric rolling and Symmetrical roll. So it can process forward bending and backward bending.
3. The operational program is easy to use, so anyone can operate it.
