The Superiority of Draw Bending: Ram Bending vs. Compression Bending
Tube bending is a crucial process in various industries, from manufacturing heavy-walled stainless steel pipes for nuclear reactors to crafting delicate precious-metal tubing for jewelry. Among the available bending methods, draw bending stands out as the preferred...Selecting the Right Mandrel and Wiper for Cost-Effective Tube Bending
Whether the times are lean or fat, cost-effective tube bending always makes sense. Just like any other manufacturing operation, keeping rotary-draw tube bending profitable means process control. That means: (1) Bringing under control all of the elements of the...Improve bend quality and cut costs by choosing the ideal wiper die
When your next rotary draw bending application calls for a wiper die, you might want to think twice about which type of wiper you should use. The purpose of a wiper die is straightforward: filling the gap between the tube and the bend die, opposite the pressure...Optimizing tube bender tooling to improve results
Excess bender force cannot overcome a poor setup or worn tools Programmability, speed, accuracy, and of course power are just some of the many advancements in modern CNC and NC rotary draw, mandrel-capable tube bending machines over the last few decades. However, even...Squaring up your next nonround bending application
Rigidity, aesthetics, and weight are at the top of the list of factors that engineers at the OEM level must consider when deciding between round or nonround tubing for design projects. Conversely, formability, weldability, and repeatability are the primary concerns of...Bending Aluminum Tube
The perception that aluminum is typically tougher to weld or paint than most other metals used for fabrication is pervasive, so it’s not surprising to learn that that bending aluminum tubing requires a bit more consideration than most other tubular materials. Material...Steps to troubleshooting draw bending of tube
Precisely positioning the tooling can result in repeatable and quality bends Even though we are in the age of CNC machinery, the old phrase “the tools make the bend” is as relevant today as ever. As tube bending applications have become more extreme (see Figure 1),...The Mandrel Nose Placement Calculator
This is a very helpful interactive utility that calculates the ideal placement of the mandrel nose. It also generates the ideal mandrel nose diameter for your specific application. This set-up tool should be used in conjunction with the “Forward Mandrel, Low...The “Forward Mandrel” Secret of Tube-Bending
Rotary-draw bending, or draw bending for short, is the best means of consistently producing high-quality tube bends, whether the application is heavy-walled stainless steel pipe for a nuclear reactor or delicate precious-metal tubing for jewelry. This is because,...The Wiper Feathered Edge
In rotary-draw tube-bending the tools make the bend. Small variations or errors in the design, manufacture, or set-up of rotary-draw tools can lead to loss of process control, poor bend quality, abbreviated tool life, and other headaches. This includes the wiper die....Link Dimension Reference Chart

A complete guide to the principles of the 4-Step set-up for tube-bending tools
This is a printable handbook showing how to implement in four standardized steps the “forward mandrel” set-up for rotary-draw tube-bending machines and establish process control over the so-called black art. The procedure is based upon the guiding principle that the tools make the bend and takes advantage of the inserted design of modern mandrel tooling.
