Mandrel bending is a precise tube bending process that uses an internal mandrel to support the tube during the bending operation. It reduces wrinkling, flattening and ovality and is therefore ideal for thin-wall tubes and tight radius bends. Mandrel bending is common in automotive, aerospace, HVAC, furniture and industrial applications.

Among the modern manufacturing methods for tube bending, rotary draw bending (RDB) is one of the most accurate and most widely used. It is commonly used to make high quality bends in stainless steel, aluminum, carbon steel and copper tubing. Rotary draw bending is widely used in the automotive, aerospace, furniture, HVAC and medical equipment industries due to its excellent precision and repeatability.

Is there a difference between "pipe" and "tube" when it comes to pipe bending machines?

Cold bending and hot bending are the two main forming techniques used in the production of metal pipes or profiles. The choice of the procedure depends on the qualities of the material, wall thickness, bending radius and the costs of production. Here is a detailed comparison of the two methods.
