"The fundamental principle of the magnetic bending machine is that it uses an electromagnetic clamp rather than a mechanical clamping system.\nThe machine consists of a long electromagnet with a steel clamp bar located above it. Sheet metal is clamped between the two by an electromagnet capable of clamping with a force range of between 3-6 tons. Rotating the bending beam then forms the bend as the sheet is bent around the front edge of the clamping bar.\nThere are 4 different types of clamping bar used to form different folds."
