The Rolling and Mandrel Method for Metal Bending

June 10th, 2008

We rely on curved metal beams, pipe, tubes, and angles in everything from a simple park bench to spiral staircases to some parts of modern skyscrapers. Here are just two ways to do it.

 

Rolling for Metal Bending 

Rolling to bend metal is the best know method and least costly. There are different kinds of rolling processes such as hot rolling, which is used to produce sheet metal, and cold rolling, which is used for most non-ferrous metal structures. Rolling requires less set-up time and uses pre-made dies, so the cost is less than other ways to bend metal.

 

Mandrel for Metal Bending

Mandrel metal bending is the process of using a metal shaft, or mandrel, which is fitted inside a metal tube or pipe. As the mandrel moves, it bends the metal around the appropriate sized die to form the radius. However, mandrel can only bend metal tubing up to 180 degrees.
