A bend fixture for bending metal sheet includes a stationary platen, a hinged platen, and a hinge associated with the hinged platen. Each platen includes an exterior surface portion for supporting a metal sheet; an interior surface portion spaced from the exterior surface portion; and a slanted surface portion between the interior and exterior surface portion. The exterior surface portions of the platens are initially separated by a gap. Rotating the hinged platen about the hinge narrows the gap and causes the slanted surface portions to approach each other. A clamp above each platen supports the metal sheet adjacent the platens as the hinged platen is rotated. Bending metal sheet with the claimed bend fixture avoids surface galling associated with prior art sheet bending techniques relying upon interaction between a punch and a die.
