What is a Tube Bending Machine?
A Tube Bending Machine refers to an industrial machinery that is applied in bending metal pipes and tubes to a certain angle and shape without damaging their structure. It is similar to a controlled bending system in which the tube is clamped and bent around a forming die to form smooth uniform bends.
Types of Tube Bending Machines
As leading Tube Bending Machine manufacturers in India, Nisha Engineering Works provides bending machine in diverse capacities and design to meet diverse needs in the industries.
1. By Power Source
- Manual Tube Bending machine: These models are based on physical labour of the operator to either push or pull the tube around a forming die.
- Hydraulic Tube Bending Machine: By hydraulic pressure, these machines are more vigorous, move smoothly and have a higher level of accuracy.
- Electric Tube Bending Machine: They come with electric motors and can be bent and come in portable bench-top varieties and in larger models.
- CNC Tube Bending Machine: It is fully automated and computer-controlled and therefore exceptionally accurate and repeatable.
- Hybrid Tube Bending Machine: These systems have the combination of servo-electric drives and hydraulic assistance which provide high precision, speed, and flexibility.
2. By Bending Technique
- Rotary Draw Bending: A rotating die is used to create controlled and clean bends on the tube by pulling it around the die. It can bend around tight radius with the support of a mandrel without collapsing the tube.
- Compression Bending: A fixed die receives the tube and the moving arm compresses and bends around the shape. The diameter of each tube has a tendency to be supported by each machine.
- Roll Bending: The tube is formed into large-radius arches using a collection of three or four rollers. It is used with curved frames, rings and structural bends.
- Ram Bending: The bend is formed by forcing the tube over a die with a hydraulic ram. It is a simple method which is commonly employed with simpler shapes and the bigger tube sizes.
- Mandrel Bending: It is a tube and pipe bending process incorporating an internal support-mandrel-that prevents the material from deforming, wrinkling, or even collapsing on the inside of the bend.
Other Types
- Twin Head Benders: They are used to bend both sides of a tube at the same time and are best suited to a symmetrical part of a component such as furniture frame, furniture handle, or car parts.
- Heat Induction Bending: Under this technique, the tube is heated to a regulated temperature and then bent. It is mostly applied in large industrial pipelines.

Features of Tube Bending Machine.
- Stable Bending Mechanism: The solid bending arm and robust clamping mechanism of the machine make sure that it does not have difficulties in bending.
- Manually adjustable Control Settings: Angles, pressure and bending radius can be fine-tuned by the operators to suit the tube profile.
- Well-Balanced Structure: Reinforced frame removes the vibration, helps to maintain the regularity, and assists the prolonged movement of continuous bending operations.
- Safety-Integrated Operation: Switches of electrical protection, emergency stop switches, and hydraulic pressure under control are used to ensure safe working conditions.
- Intuitive User Controls: The bending process is easily managed by using simple control panels that are marked in clear ways and require less training to the operators.
Applications of Tube Bending machine.
- Fabrication of Industrial Pipes and Lines: They are useful in forming pipes which are used in hydraulic circuits, fuel lines, and industrial fluid transportation configurations.
- Frame and Automotive Exhaust Manufacturing: Bearing aids in bending of exhaust pipes, roll cages, chassis frames and protective metal structures.
