Ram Forming
Ram forming is quicker and usually preferred when speed of production is a concern. The automotive industry usually uses this process over internal roll-forming. A clamp is used to hold the tube, the tube is expanded to desired diameter by an expansion punch, and then another punch is used to reduce the tube back to pilot diameter. Multiple beads are possible using this process.

Famous quotes containing the words ram and/or forming:
“At one time or another, almost every politician needs an honest man so badly that, like a ravenous wolf, he breaks into a sheep-fold: not to devour the ram he has stolen, however, but rather to conceal himself behind its wooly back.”
—Friedrich Nietzsche (1844–1900)
“The structure was designed by an old sea captain who believed that the world would end in a flood. He built a home in the traditional shape of the Ark, inverted, with the roof forming the hull of the proposed vessel. The builder expected that the deluge would cause the house to topple and then reverse itself, floating away on its roof until it should land on some new Ararat.”
—For the State of New Jersey, U.S. public relief program (1935-1943)
