CNC Radiator Core Assembler | Automatic Radiator Core Assembly
Machine
Product Overview
The CNC Radiator Core Assembler, also known as a radiator core builder, fin-to-tube insertion
machine, or radiator core assembly machine, is designed for
assembling automotive radiators, condensers, intercoolers, oil
coolers, and other heat exchanger cores.
The machine precisely inserts and positions cooling fins onto flat
or round tubes to create a uniform core structure. Accurate tube
pitch and fin spacing help produce a consistent semi-finished core
ready for subsequent tube expansion and brazing processes.
With CNC control, servo-driven feeding, and customizable fixtures,
the machine can be configured for different core sizes, tube
materials, fin designs, and row configurations. It is suitable for
both OEM and custom heat exchanger manufacturing.
Key Advantages
Precision CNC Control
The industrial PLC and touchscreen CNC interface allow operators to
set production parameters and change between different core
specifications. Servo-driven feeding provides accurate fin and tube
positioning with repeatable assembly performance.
Rigid Vertical Gantry Structure
The heavy-duty welded frame provides stable support during
operation and helps maintain alignment accuracy across different
core dimensions, making the machine suitable for demanding radiator
and heat exchanger manufacturing environments.
Wide Compatibility and Customization
The machine supports aluminum and copper tubes and different fin configurations, tube pitches, and row
arrangements. It can be customized for automotive radiators,
commercial vehicles, construction machinery, intercoolers, and
aftermarket heat exchangers.
Flexible Automation
Automatic and semi-automatic configurations are available for
different production volumes and investment requirements.
Hydraulic/pneumatic positioning combined with servo-driven feeding
provides smooth material handling during core assembly.
Applications
The CNC radiator core assembler can be configured for:
- Automotive radiators
- Condensers
- Intercoolers
- Oil coolers
