Extruded fin tube machine is a kind of equipment that can increase the heat exchange area.
Extruded fin tube machine is also called “Gj-66b fin tube making machine”. It is to line copper tube or steel tube (also called base tube) with aluminum tubes of different specifications, and then roll and compound them through the cutter in the unit, and extrude fins at one time, in order to increase the heat exchange area.
Features of Extruded tube finning machine It has compact structure, stable performance and convenient operation.

Extruded Fin Tube Machines: Functionality and Production Capabilities
Introduction to extruded tube finning machines
Extrusion fin tube machines are specialized industrial equipment designed to manufacture high-efficiency heat transfer tubes with integral fins. These machines use a cold-forming process to extrude fins from the base tube material, creating a seamless, durable heat exchange surface with excellent thermal conductivity.
Machine Functionality
The primary functions include:
- Simultaneous fin formation and base tube processing
- Precision control of fin dimensions and spacing
- Automated production with consistent quality
- Capability to process various metallic materials

Extruded tube finning machine Applications
Extruded fin tubes are widely used in:
- HVAC systems
- Power plant condensers
- Refrigeration equipment
- Industrial heat exchangers
- Petrochemical processing
The extrusion process creates fins with superior bond strength compared to welded or embedded fins, resulting in longer service life and better heat transfer efficiency.
