A wiper die – contacts the tubing right before the inside radius’s tangent point, wiping against the workpiece to prevent wrinkles on the inside radius.

A mandrel – supports the tubing interior around the bend and may come with some articulating balls.

A clamp die – rotates the steel tubing around the bend die.

A pressure die – this die hold the tangent (or the straight section) of the tub.

The setup for mandrel tube bending include: Mandrels may come with additional ball-shaped steel to ensure they stay inside the curved sections of bends during the bending process. A mandrel is a tool put inside a tube to ensure its shape remains intact while bending.

Mandrel bending of metal tubing is often done on a rotary draw tube bending machine.

This section will discuss how to bend stainless steel tubing using the most effective methods.

However, some techniques can help simplify the process. It is pretty tough to deal with stainless steel tubing. The possibility of spring back occurring also poses a significant challenge to bending stainless steel tubing. Furthermore, specific sizes and shapes of tubes may require their set of bending equipment. Thick-walled tubing usually needs increased force to bend. The difficulty often depends on the thickness of the tubing. When we talk about bending high-end stainless steel materials, attention turns to increased bending difficulties. Stainless steel tube bending is a process that helps to shape the tubing into several valuable configurations.Īlthough it is possible to bend stainless steel into different shapes, the process may require considerable direct pressure for specialized tools. It is easily formed with various machining processes into several shapes. However, it is a ductile and malleable material.

Using steel for custom prototyping can be tricky. Basics and Challenges of Bending Stainless Steel Tubing We would also guide you through getting the best out of the process. In this article, we will discuss the most effective methods of bending steel tubing. Therefore, it is essential to know how to go about the bending process. Some high-end stainless steel materials are now mainstream, compounding their machining challenges. However, a proper understanding of how to bend steel tubing is needed. Engineers and designers consider it a principal operation as part of a system tubing and piping. This makes bending stainless steel tubing is a standard forming process for manufacturing metal parts for various applications. Stainless steel is one of the most popular materials in the manufacturing industry.
