Tube bending

As a cold forming process, tube bending preserves the material’s original structure, ensuring a high level of stability. Our machines can produce even the most complex geometries with short straight sections between bends using a variety of bending processes. They can be used either as space-saving stand-alone solutions or as part of a highly automated production cell.

How does tube bending work?

When tubes are bent using CNC-controlled Felss machines, the tube sections to be processed are automatically fed into the machine and formed. Roll, draw, push-roll and collet bending can be performed from either end of the tube using just one bending head. This gives users maximum design freedom, even when manufacturing highly complex components. Felss uses these same process terms on its English-language CBC machine page.

Applications of tube bending

Felss tube bending machines can produce even highly complex tube geometries. This makes them an ideal choice for manufacturing brake and clutch lines as well as injection systems for diesel and petrol engines. They can also produce a wide variety of tube-hose assemblies and circular hollow sections.

Advantages of tube bending

• Highest bending quality thanks to maximum tube circumference
• Special tool geometry minimises tube collapse
• Small radius-to-diameter ratios and complex tube geometries
• Roll, draw, push-roll and collet bending from both ends of the tube

Bending tubes with the Felss Combined Bending Center

The Felss Combined Bending Center (CBC) tube bending machines provide comprehensive solutions for bending steel tubes and other materials, including copper tubes. Thanks to their modular design, our machines can be configured according to individual requirements.

Would you prefer Felss to bend your tubes for you?

Felss also provides component manufacturing services for customers who do not operate their own bending machines or require additional support during periods of peak demand. We deliver precisely bent, high-quality tubes for the automotive, industrial and aviation sectors at competitive prices and with fast order processing.

Thanks to our wide range of additional in-house technologies, we can manage the complete manufacturing process for your components, from the blank to the finished part.

Why should tubes be bent using a cold forming process?

Unlike hot forming, cold forming processes are particularly gentle on the material when bending tubes, as the metal is not exposed to heat that could alter its crystalline structure. They are also highly efficient because no time or energy is required to heat the material.

This enables tubes to be bent in a particularly precise and material-efficient manner.

Tube bending in summary

Tube bending is a forming process used to shape tubes precisely and without applying heat, thereby maintaining material stability. Modern CNC-controlled machines enable the accurate production of complex geometries, particularly for automotive applications. Cold forming is both efficient and material-friendly because the material does not need to be heated.
