Extruded Fin Tube Machine
Extruded fin tube machine also called tube finning machine and finned tube rolling machine, bi-metallic fin tube machine, high fin tube machine, etc., for rolling single or dual-metal finned tubes used in heat exchangers and heaters.
The extruded finned tube machine roll the aluminum tube onto steel or copper liner tube, to get more heat exchange area with extruded fin. The suitable material can be copper-aluminum, steel-aluminum, aluminum, copper and steel.
Datang has been manufacturing finned tubes and fin tube machines for nearly 20 years. Our experienced technicians can provide video guidance or visit your site to help you install our extruded fin tube machines. We welcome your inquiries!
What is an extruded fin tube machine?
Extruded fin tube machine also called tube finning machine and finned tube rolling machine, bi-metallic fin tube machine, high fin tube machine, etc., for rolling single or dual-metal finned tubes used in heat exchangers and heaters.
The Bimetallic extruded finned tube making machine is used to make the integrally formed finned tube with an excellent fin-to-tube bond providing exceptional efficiency and longevity. Whether rough service, high temperatures, or corrosive environment, extruded fin tube is the best option for heat exchanger applications.
Main features of extruded fin tube machine ( bi-metallic fin tube machine):
1) Tool holder and tool holder body adopt the advanced dual-circular key structure to withstand torque, displacement of accurate and reliable.
2) Tool holder adopt split type design, it is very easy to blade debugging, washable and install of the blade.
3) Spindle bearing can be moved using conical hydrodynamic sliding bearings, bearing to maximize the utilization.
4) Universal joints and shaft key link between all lines of Hot Pepper. Cooling box separate from rolling mill machine.
5) Closely with technical data, rolling fin efficient, durable blades.

Extruded Fin Tube Machine Blades
The blades of the extruded fin tube machine are key components in the roll-to-laminate process. They extrude aluminum or copper tubes, creating a finned structure in a single operation. The blades mechanically extrudes spiral or custom-shaped fins onto the tube’s exterior surface. The shape, spacing, and thickness of the fins can be customized to your needs.
Fin Tube Extruded Machine Rolling Mechanism
They are precision and rigidity fin tube machine. You can operate this machine with quality, durability and high production speed.
Three Sets of Pressing Devices for Extruded Fin Tube Machine
The pressing device of the extruded fin tube machine uses a threaded pair to control the rolling pressure, and the helix angle adjustment mechanism realizes angle adjustment through the positioning block and the adjusting bolt.
Integral Extruded Rolled Fin Tube Machine Packaging
1. Use wooden boxes or steel frames as the primary packaging structure.
2. Fill the interior with shock-absorbing material (such as foam plastic or bubble wrap) to prevent movement or collision during transportation.
3. Precision components must be individually wrapped with anti-static material.
4. The main body of the device must be bolted or welded to the packaging base to prevent tipping.
Extruded Fin Tube Stripping Machine
The extruded fin tube stripping machine is mainly used to remove the fin structure at the end of the fin tube to facilitate subsequent welding or connection operations. It achieves non-destructive fin removal through mechanical cutting or hydraulic stripping to avoid damaging the base tube surface.
