High Precision Custom Coil Cut to Length Line for Radiator Core Production

The fully automatic metal coil cut to length line (CTL line) and precision blanking line is specifically engineered for the heat exchanger industry, including automotive radiators, condensers, and evaporators. This high-efficiency automated coil processing equipment integrates decoiling, precision leveling (roller leveler), servo-driven cut-to-length shearing, conveying, and automatic stacking into one seamless production line. It converts aluminum coil, steel coil, and stainless steel coil into high-precision, high-flatness sheets, serving as the essential upstream equipment for automotive radiator core production.

• Heat Exchanger Industry Optimization: Specially designed for thin-gauge aluminum foil and hydrophilic foil used in automotive radiators. The precision leveler features anti-scratch treatment to protect the oxidation layer and hydrophilic coating, ensuring consistent downstream brazing quality.

• Superior Accuracy and Stability: Full closed-loop servo control system delivers cut-to-length accuracy of ±0.3mm per 1000mm and sheet flatness ≤0.5mm/m. The finished sheet flatness and dimensional consistency exceed industry standards, meeting the rigorous demands of radiator core mass production.

• High-Efficiency Automation: Fully automatic cut to length line operation from coil loading to finished sheet stacking requires only 1–2 operators. The system significantly reduces labor costs while boosting productivity through unmanned workflow.

• Flexible Customization: Configurable based on specific coil dimensions, finished sheet sizes, and production speeds. Supports custom widths (300–1600mm) and custom cut to length (300–3000mm or longer). Seamlessly integrates with downstream equipment such as tube expanders and brazing furnaces to create a complete heat exchanger production line.

• Easy Maintenance and Safety Design: Critical components are sourced from internationally renowned brands for extended service life. Equipped with safety light curtains, emergency stop systems, and tension alarms to ensure operational safety and minimize downtime.

1. Decoiling: The coil is loaded onto the decoiler via overhead crane. The expandable mandrel grips the coil ID, while a tension control system prevents slack and deformation.

2. Feeding and Leveling: The strip is fed by pinch rollers into the multi-roll precision leveler, where leveling rolls eliminate internal stress and waviness, ensuring optimal flatness for subsequent metal fabrication.

3. Servo Cut-to-Length: A servo-driven measuring system tracks material feed length in real time with high-resolution encoders, guaranteeing cut length accuracy within ±0.3 mm.

4. High-Speed Shearing: Pneumatic or hydraulic shear delivers burr-free, square cuts ideal for subsequent tube expansion and brazing processes.

5. Conveying and Stacking: Cut sheets are transported to the automatic stacker and neatly piled onto wooden pallets. The system supports layer counting and scratch-prevention features.

This coil cut to length line is widely used by manufacturers of automotive radiators, condensers, and evaporators. It provides precision sheets for core aluminum foil, header plates, and side plates, meeting the high-volume production demands of auto parts factories in regions such as the Middle East and India. The system also serves as a reliable coil processing equipment solution for HVAC systems and other industrial heat exchanger manufacturing applications.
