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.
