Rotary Draw Bending
Precision Bending Technologies specializes in rotary draw bending, a sophisticated tube forming process that delivers exceptional quality and precision for demanding applications.
Superior Control and Precision
Rotary draw bending utilizes internal mandrels and precision tooling dies to provide unmatched control throughout the bending process. This advanced method enables us to achieve tight radius bends while maintaining strict dimensional tolerances that other bending techniques simply cannot match.
Quality You Can See
The rotary draw process produces smooth, consistent bends with an aesthetically pleasing finish. When appearance matters—and it often does—this method ensures your components look as good as they perform. The clean, professional results make rotary draw bending the preferred choice for visible applications where both form and function are essential.

ROTARY DRAW BENDING
Our rotary draw bending technology employs mandrels and various dies to manage and control metal flow during the bending process. Rotary draw bending is a process in which a precision mandrel is positioned inside the tube, while a pressure die, wiper die, bend die, and clamp dies surround the outside of the tube. This provides a smooth, aesthetically pleasing appearance while maintaining the full diameter of the tube throughout the bend area.
This method finds application in fluid handling lines. It is often used in products when bend cosmetics are important and applications where extremely “tight” bend radii or small dimensional tolerances are desired. These attributes are unique to this type of bending and are not possible with other less controlled bending processes.
Rotary draw bending is not limited to tube and pipe. It can also be employed to bend extruded shapes, square and rectangular tube and pipe, and channel.
We have a wide selection of tooling along with our in-house CNC machining capabilities. In addition, we can produce special tooling quickly to meet your specific project needs.

Precision Tube Bending
Certain applications require precision tube bending that causes the need for accurately threaded brackets and ends. In these projects, ensuring tubes mate together precisely is key. The ends of the tube must be free of distortion. Our precision tube bending process uses tools and gauges that help create the desired outcome in fit and performance.
Roll Bending
Roll bending, as the name suggests, uses a machine with 3 rollers, known as a jig. Custom bending can be used to bend both sheet metal and metal bars.
Roll bending works by placing the tube into the jig and then manually lowering and pressing the middle roller onto the tube, shaping it into the desired custom shape.
This form of custom bending is good for some circular designs.
Press Bending
The simplest and most common form of custom tube bending is press bending.
This is not the most precise form of custom tube bending, however. The process involves pressing a “bend die” against the tube or pipe to create the desired shape.
