CNC Radiator Core Assembler Precise Fin To Tube Insertion And Custom Fixture Design
The CNC Radiator Fin Insertion Machine, also referred to as a radiator core builder, fin tube insertion machine, or radiator core assembly machine, is the core production equipment for manufacturing automotive radiators, condensers, and heat exchangers.
This automatic core builder is specifically engineered to precisely insert and position cooling fins onto flat or round tubes, creating a uniform core matrix for cooling systems. The process ensures consistent tube pitch and fin spacing, delivering a high-quality semi-finished core assembly ready for the subsequent tube expansion process.
As a comprehensive equipment supplier in the field of heat exchanger manufacturing equipment, this machine is ideally suited for the production of automotive radiators, intercoolers, oil coolers, and HVAC systems.
- Precision CNC Control System
Equipped with an industrial PLC and intuitive touchscreen interface, this automatic core assembly machine allows for straightforward parameter setting and fast changeover between different core sizes. The CNC radiator fin machine utilizes a servo motor driven feed to ensure high-accuracy insertion, positioning, and repeatability across high-volume production runs. - Rigid Vertical Gantry Structure
The robust welded frame minimizes vibration and ensures exceptional stability during high-speed insertion. This heavy-duty structure maintains alignment accuracy across various core dimensions, making it a reliable core forming machine for demanding industrial environments. - High Compatibility and Customization for Global Markets
Designed to handle a wide range of fin types and tube materials, including aluminum and copper. The radiator core builder easily adapts to different tube pitches and row configurations, meeting the specific requirements of commercial vehicle, construction machinery, and aftermarket radiators prevalent in Middle Eastern and Indian markets. We provide tailored radiator fin machine solutions for both OEM and custom manufacturing applications. - Flexible Automation Options
Available in automatic and semi-automatic core builder configurations to suit different production volumes and budget requirements. The system utilizes hydraulic/pneumatic positioning combined with servo-driven feed for smooth material handling and efficient heat exchanger core assembly.
