Tube bending
Tube bending is a processing process where tubes of different materials are bent or shaped to the desired geometry. This is usually done using special machines called tube bending machines or tube benders. The process is essential for manufacturing tube components that require bent shapes to fit specific designs and functions.

The process of tube bending
Preparation of the tube:
A tube of the desired material - usually metal such as steel, stainless steel, aluminum or copper - is prepared by being cut to the appropriate length and prepared for bending.
Bending:
The tube is fed into the pipe bending machine where it is passed through a series of forming tools. These tools bend the tube according to the specified radius and angle to achieve the desired bent shape. Tube bending machines can be manual, semi-automatic or fully automated depending on the complexity of the bend and the volume required.
Checking and adjusting:
During the bending process, the machine is monitored and adjusted to ensure that the bend is correct and that the tube is not deformed or damaged.
Completion:
After the tube has been bent to the desired shape, it may need further machining or adjustment to ensure that all dimensions and tolerances are met.
Types of tube bending machines
There are different types of tube bending machines:
Manual tube bending machines:
These require manual manipulation by the operator to bend the tube.
Hydraulic tube bending machines:
Uses hydraulics to apply the force needed to bend the tube, making it possible to handle larger and thicker tubes.
CNC controlled tube bending machines:
Automated machines that are programmable to bend tubes in complex geometries and to achieve high precision and repeatability.
Materials and tolerances
Tube bending can be performed with different materials and tolerance requirements depending on the application. Material choices typically include steel, stainless steel, aluminum, copper, and other metals. Tolerances are important to ensure that bent tube fittings fit perfectly with other components of a construction or installation.
Areas of use
Tube bending is used in a variety of industries and applications, such as:
Automotive industry:
Manufacture of exhaust systems, frame components and cooling systems.
The building and construction sector:
For the installation of tubes, handrails and other architectural and structural applications.
Industrial Fabrication:
For the manufacture of tube bends and tube bent components used in machinery and equipment.
Tube bending is an important technology in the manufacturing industry that makes it possible to produce precisely bent tube fittings for a variety of uses, from industrial to commercial applications.
