Heater Core Assembly Machine – Precision Assembly Solution for Automotive Heat Exchangers
Product Overview
The Heater Core Assembly Machine is a professional radiator core assembly machine designed for automotive heater core and small heat exchanger production.
It precisely assembles flat tubes, aluminum fins, main plates, and side plates into complete core structures before brazing. By improving tube positioning accuracy and fin alignment consistency, this core builder machine helps manufacturers reduce manual errors, improve production stability, and achieve better brazing performance.
Based on years of experience in radiator and heat exchanger manufacturing equipment, SUNHOPE develops assembly solutions suitable for automotive radiator factories, OEM suppliers, and heat exchanger manufacturers.
Besides heater cores, this machine can also be customized for the assembly of certain small condensers and evaporator cores, providing greater production flexibility.
Key Advantages
High Precision Assembly
The machine uses a servo motor and pneumatic positioning system to ensure accurate core assembly.
It maintains consistent:
- Flat tube positioning
- Fin spacing
- Core dimensions
- Assembly quality
With positioning accuracy up to ±0.01 mm, it helps improve the reliability of subsequent aluminum brazing processes and reduces quality issues caused by incorrect assembly.
Flexible Changeover for Multiple Models
Different heater core designs often require different dimensions and tooling. This machine supports fast changeover through customized fixtures and tooling systems.
It is ideal for manufacturers producing multiple models with small and medium production volumes.
The equipment can be integrated with:
- Fin Forming Machines
- Aluminum Fin Press Lines
- Tube Expanding Machines
- Aluminum Brazing Furnaces
- Leak Testing Equipment
to build a complete heat exchanger production line.
Efficient and Stable Production
Compared with manual assembly, the Heater Core Assembly Machine provides:
- Higher assembly consistency
- Reduced labor dependency
- Faster production cycles
- Improved production efficiency
The standard model achieves an assembly cycle time of approximately 25 seconds per unit, depending on product specifications.
