(AJL21) Medium-Speed Aluminum/Copper Fin Press Machine Line (for Heat Exchangers) The high-speed aluminum fin press machine line for air conditioners consists of an exhibition press, oil device, pneumatic initial feeding system, closed-type high-speed precision press, vacuum suction unit, material collection device, electric control system, and hydraulic system. This machine is specifically designed for manufacturing aluminum fins used in automotive components such as water tanks, intercoolers, condensers, evaporators, and heater units. Equipped with PLC and servo control systems, it supports one-time form rolling, drying, and fixed-length cutting. The machine features a quick-change die system, making it ideal for various fin production needs. Key Features: 1. Power press speed and vacuum sucker are controlled via a converter. Hydraulic lifting function allows easy mold adjustment. 2. Includes aggregate error detection, no-oil warming, and material detection alarm protection. 3. Hydraulic overload protection ensures die safety and ease of use. 4. Quick die change mechanism improves efficiency during production transitions. 5. Thick oil lubrication system with alarm function helps maintain smooth operation. 6. PLC-based centralized control system provides multiple functions and user-friendly interface. 7. Optional automatic scrap blowing device available for enhanced efficiency. Below is a detailed specification table for different models of the medium-speed and normal-speed aluminum/copper fin press machine lines:
