Application Scope
Automotive Cooling: Radiator cores, air-conditioning condensers, and evaporator fins.
Electric Vehicle (EV): High-efficiency battery cooling plates and thermal modules.
Heavy-Duty Transport: Cooling systems for trucks, buses, and construction machinery.
Industrial HVAC: Heavy-duty industrial heat exchanger fin systems.
Main Equipment Modules
Coil Uncoiler: Equipped with automatic tension control for smooth material payoff.
Straightening & Feeding Unit: High-torque servo feeder ensuring micro-level feeding accuracy.
High-Speed Press: Robust H-frame / C-frame structure built for continuous 24/7 industrial loads.
Progressive Fin Forming Die Set: Premium tool steel die with a life expectancy of 1–5 million strokes (maintenance-dependent).
Micro-Lubrication System (Optional): Minimizes tool wear while maintaining clean foil surfaces.
Automatic Stacking System: Vacuum or mechanical stacking tailored to specific fin lengths.
Control Cabinet: Smart PLC integrated with an intuitive touchscreen interface and multi-level safety interlocks.
Production Process Flow
Coil Loading & Decoiling
Raw aluminum or copper coil is loaded and smoothly unwound through a controlled decoiling system, ensuring stable material feed without deformation or tension fluctuation.
Tension Control System
A precision tension control unit maintains constant material tension throughout the entire process, preventing material distortion and ensuring stable stamping accuracy.
Servo Precision Feeding
High-precision servo-driven feeding system synchronizes with the stamping press to ensure accurate positioning and consistent fin pitch control.
Progressive Stamping Process
Multi-stage progressive die performs all forming operations in a single continuous cycle, including:
Punching
Louver forming
Fin shaping
Edge trimming
This ensures high efficiency and consistent geometric accuracy.
Cutting & Transfer
After stamping is completed, the continuous strip is precisely cut into individual fin sheets or required lengths by a high-speed cutting system.
Transfer System
Automated transfer arms or mechanical grippers accurately move finished fins from the cutting station to the stacking area.
Automatic Stacking
Finished fins are automatically aligned and stacked in uniform batches. A precision stacking system ensures consistent layer alignment, stable stack height, and easy downstream handling for brazing or assembly processes.
Scrap Discharge System
Scrap material generated during punching and trimming is automatically separated and conveyed to a dedicated scrap collection system.
