  • The basics of roll form tooling design

    You can successfully roll-form a profile more than one way. In fact many roll form designers take different approaches to design and development. Also because the roll forming process has a seeming limitless capacity to produce complex profiles with just as many variables many roll form designs are one-of-a-kind therefore theory can go only so far.
