2. What Is an Extruded Fin Tube

A typical extruded fin tube consists of a solid aluminum or copper sleeve.
During processing, manufacturers extrude this sleeve over a base tube to form continuous, tightly bonded fins.
Through this extrusion method, the tube gains excellent heat transfer performance and strong mechanical durability.

3. Working Principle of an Extruded Fin Tube Machine

An extruded fin tube machine makes fins with a cold extrusion process. High pressure forces the aluminum over the base tube. Also, the metal flows into the fin shape without cutting or welding.

The general steps are:

• Load the base tube and aluminum sleeve.
• Position the tube inside the extrusion head.
• Start the cold extrusion system.
• Aluminum flows and forms fins.
• Measure fin height and thickness.
• Cut finished fin tubes to length.

This results in a strong metallurgical contact and good corrosion resistance.

4. Technical Details of Extruded Fin Tube Machine 

A complete extruded fin tube machine line includes several coordinated components.
First, the Tube Loading Frame holds both the tube stock and the aluminum sleeves so operators can feed materials efficiently.
Next, the Extrusion Head applies high pressure to form the fins with accurate shaping.
The Fin Height Controller then keeps the fin profile consistent throughout production.
Meanwhile, a Servo Drive System moves the tube smoothly to maintain stable extrusion.
To protect the surface quality, the Cooling and Lubrication Unit dissipates heat and minimizes friction.
Finally, the Cut-to-Length System trims each finished tube precisely to its required size.

Bangwin Thermal engineers design every machine with a rigid frame and high-accuracy machining to ensure durable, long-term operation.

5. Features and Technical Benefits

An extruded fin tube machine offers a number of technical benefits for heat-exchanger manufacturers.
It has a powerful extrusion force, which ensures well-formed fins.
The processing method results in a smooth surface finish, which improves airflow and overall heat transfer.
Since the fins are tightly bonded to the base tube, the thermal conductivity is greatly enhanced.
Operators can also easily modify the fin height and geometry to suit different engineering needs.
The machine’s precision-built components also ensure uniform spacing for consistent quality.
The machine is compatible with aluminum and copper sleeves, so manufacturers can choose the most appropriate material.
The machine also maintains stable output performance, which is ideal for long production cycles.

6. Advantages of Extruded Fin Tube in Heat Exchanger Manufacturing

The use of extruded fin tube machine has some definite advantages, which include the following:

1. Enhanced thermal performance:Greater metal contact and efficient heat transfer.
2. Extended service life:The bonded fins do not loosen.
3. Corrosion resistance:Aluminum and copper offer excellent corrosion resistance.
4. Superior strength:The extruded fins are robust and have better resistance to mechanical damage.
5. Reduced maintenance:The manufacturing process helps to reduce fin gaps and dust accumulation.

The reasons above account for the preference of extruded fin tubes in many industries.
