If you want to become a sheet metal fabricator, you need to ensure that your basics are strong. While technologies may evolve, most fabrication principles do not change. Pipe and tube bending is a tough challenge for novices. It is all about using the right method for the right application. In this blog, we shall discuss the various tube bending methods in detail.
Overview of Tube Bending Methods
The below information will allow you to understand how each method is used, as well as the right application to use them.

- Rotary Draw: Also known as mandrel bending, rotary draw bending is the most common bending method used by fabricators. It is versatile, as it can achieve high quality bends and tight radii. Rotary bending involves using a mandrel with multiple dies, including a bend, clamp, and pressure die. The rotary action of the mandrel draws the pipe around the bend die, making the desired bend in the material. This method allows for the production of accurate components. Multiple radii parts can also be made as the dies control the bending process. This method is not appropriate if the part design is not finalized, or the part has only large radii bends.
- Compression Bending: This method involves using a tube bender, a bend, and a compression die. During the bending procedure, the bend die remains stationary while the counter die compresses the material around the bend die. This bending method is used to manufacture products like handles, furniture, and frames. It is the ideal procedure when you wish to manufacture multiple items at low costs and high speeds. Compression bending is not appropriate when the part needs to be symmetrical, has exact bend roundness, and with complete multiple radii.
