Return Bends at High Production Speeds

OAK small bending machines turn out multiple bend angles easily and dependably. The cuts are straight and bend centers are accurate, protecting your investment in the quality of your final product.

This machine is specifically designed to produce return bends at high production speeds. This machine automatically feeds, bends, and cuts off return bends using an electric motor drive with cam operated mechanisms. The Mechanical Return Bender has no hydraulics and requires only electrical and pneumatic connections.
