The High Precision High Efficiency Multi-Row Radiator Core Fully Automatic Assembly Machine is an advanced automated solution designed for the production of automotive radiators, charge air coolers, condensers, and other heat exchangers. Serving as a specialized radiator core assembly machine and core builder machine, it completes the precise assembly of flat tubes, fins, headers, and side plates in a single cycle—delivering a finished radiator core ready for brazing.

Built to support multi-row configurations (1–4 rows and above), this radiator machine accommodates a wide range of applications, from passenger vehicles and commercial trucks to construction machinery and new energy vehicles. The system integrates servo drives, PLC control, and automated tube feeding, fin placement, positioning, pressing, and optional tube expansion—functions that can be further enhanced with tube expanding machine or hydraulic expander machine modules. By combining high precision with high efficiency, it significantly reduces manual labor while ensuring consistent product quality.

• Servo-driven positioning ensures accurate flat tube center distances and fin alignment.

• Dimensional tolerances are tightly controlled, directly improving brazing yield and thermal performance.

• Repeatability and stability guarantee consistent core geometry across high-volume production runs.

• Single-cycle time: 45–90 seconds, depending on core complexity.

• Production capacity exceeding 60 units per hour—far surpassing manual assembly methods.

• Rapid cycle times combined with minimal downtime maximize overall equipment effectiveness (OEE).

• Rapid changeover capability allows handling of cores with varying sizes, row counts, and tube configurations.

• Ideal for high-mix, low-volume production environments.

• Touchscreen HMI provides intuitive parameter setup, real-time monitoring, and fault diagnosis.

• Short operator training time reduces onboarding costs.

• Fully enclosed safety doors, light curtains, and emergency stop buttons ensure compliance with industrial safety standards.

• Automotive radiators, charge air coolers, condensers, evaporators, and heater cores

• High-volume production of aluminum brazed radiators for passenger vehicles, commercial trucks, construction machinery, and new energy vehicles

• Radiator remanufacturing, core replacement, and custom production in repair and modification facilities

To meet diverse production requirements, the machine can be equipped with additional modules:

• Tube Expanding Unit – Integrated as a dedicated tube expanding machine or hydraulic expander machine for automated tube expansion prior to brazing

• Multi-Row Configurations – Support for 4+ rows available upon request

• Extended Size Ranges – Customized core dimensions to accommodate specialized product lines

• Data Integration – Connectivity options for MES (Manufacturing Execution System) integration

This radiator core assembly system is part of a comprehensive product portfolio for heat exchanger manufacturing. Other available systems include:

• Single-Row Core Assembly Machines

• Condenser Assembly Machines

• Charge Air Cooler Assembly Machines

• Fin Press Lines

• Brazing Furnaces

Customized solutions are available based on customer production capacity, product specifications, and factory layout requirements.
