Multi-Row Fully Automatic Radiator Core Assembly Machine | Aluminum Radiator Core Building Machine for Automotive Heat Exchanger

The Multi-Row Fully Automatic Radiator Core Assembly Machine is an advanced production system developed for manufacturers of aluminum radiators and automotive heat exchangers. It integrates flat tube feeding, fin placement, header positioning, side plate assembly, and precision pressing into one continuous automated process.

As a professional radiator core assembly machine and aluminum radiator core building machine, it helps manufacturers produce stable, accurately assembled radiator cores that are ready for brazing. Compared with traditional manual assembly methods, this automated solution improves production efficiency, reduces labor dependency, and maintains consistent product quality during high-volume manufacturing.

Designed for automotive radiators, charge air coolers, condensers, evaporators, heater cores, and other heat exchanger applications, the machine supports both standard and customized multi-row radiator core production. Servo-driven positioning, PLC control, and intelligent automation provide reliable performance for passenger vehicles, commercial trucks, construction machinery, and new-energy vehicles.

In radiator manufacturing, assembly accuracy directly affects brazing quality, thermal performance, and final product reliability. Traditional manual assembly often depends on operator experience, making it difficult to maintain consistent tube spacing, fin alignment, and production speed.

This fully automatic radiator core assembly system solves these challenges through precise automation.

The machine provides:

• Stable core dimensions through servo-controlled positioning
• Faster production cycles compared with manual assembly
• Reduced labor requirements and operating costs
• Flexible production for different radiator models
• Reliable quality consistency for continuous manufacturing

With quick parameter adjustment and customized configurations, the system is suitable for both large-scale production and manufacturers producing multiple radiator models.

The servo-driven positioning system controls tube spacing, fin alignment, and component placement with high accuracy. Stable assembly dimensions improve brazing efficiency and help achieve consistent heat exchanger performance.

Positioning accuracy can reach ±0.1 mm, ensuring reliable production quality across different manufacturing batches.

The machine completes a full assembly cycle in approximately 45–90 seconds, depending on radiator design and production complexity.

With output exceeding 60 units per hour, it provides a significant efficiency improvement compared with manual assembly, helping manufacturers increase production capacity while maintaining stable quality.

The equipment supports:

• 1–4 row radiator cores
