The electro-deposited copper foil machine produced by Hongtian Technology Co., Ltd. is an integral part of lithium-ion battery production. Copper foil serves as the anode material for these batteries, and its quality directly influences the battery’s performance. The machine uses an electro-deposition process, where copper is deposited onto a cathode roller to create thin copper foil. This process must be highly controlled to ensure the foil meets the strict specifications for use in lithium batteries. The company's equipment is designed to produce copper foil with precise thickness and width, ranging from 3.5µm to 105µm, and widths from 1000mm to 2000mm. These specifications are vital for ensuring the efficiency and performance of lithium-ion batteries, which are extensively used in electric vehicles, mobile devices, and renewable energy storage.
The Hongtian Technology Co., Ltd. electro-deposited copper foil machine features cutting-edge technology and high control accuracy. With advanced components and systems that ensure precise tension, temperature, and polishing controls, the machines are engineered for optimal production speed (0~20M/min) and reliability. This level of precision helps to maintain consistent foil thickness, which is crucial for the performance and safety of lithium batteries. 

2.Equipment Composition and Key Components
The electro-deposited copper foil machine is made up of several critical components that work together to produce high-quality copper foil suitable for lithium-ion battery production. Each section of the machine is designed to ensure maximum precision, efficiency, and consistency in the production process.
Lithium Battery Foil Production Machine: At the core of the copper foil production system is the electro-deposited foil production machine. This machine uses an electro-deposition process to coat copper onto a cathode roller, which then forms the copper foil. The machine is capable of producing copper foil in a range of thicknesses (3.5μm to 105μm), making it versatile enough to meet the needs of various lithium-ion battery manufacturers. The foil is produced at a steady and reliable speed, ensuring uniformity in every roll produced.
Online Polishing Section: After copper is deposited onto the cathode roller, it undergoes polishing to remove any imperfections and improve surface quality. The Hongtian Technology Co., Ltd. copper foil machine includes an online polishing system that uses high-quality 3M non-woven fabric polishing wheels. The polishing speed can be adjusted between 0 to 600 revolutions per minute (RPM), offering flexibility to achieve the desired surface finish. The system also uses current detection to measure the polishing pressure, ensuring that the polishing process is consistent and doesn’t damage the copper foil.
Cathode Roller Drive Part: The cathode roller, which is the key part of the electro-deposition process, comes in various diameters, including φ1500mm, φ2016mm, and larger sizes such as φ2700mm, φ3000mm, and φ3600mm, depending on the production requirements. This section of the machine is designed to provide precise rotation and movement to ensure that copper is deposited evenly across the roller surface. 
Anti-Oxidation Equipment Section: To ensure that the copper foil remains high-quality, it undergoes an anti-oxidation treatment. This step prevents the copper from reacting with moisture and air, which could compromise the foil's performance. The Hongtian Technology Co., Ltd. copper foil machine is equipped with advanced anti-oxidation equipment that maintains an optimal environment for the foil, preventing oxidation and ensuring that the foil retains its conductivity and flexibility.
Collection Section: Once the copper foil is produced and polished, it is wound into rolls. The collection section of the machine is responsible for gathering the foil and winding it onto rollers. The machine has a maximum winding diameter of 650mm, and the roller diameter can be adjusted between 200mm and 320mm. This section is equipped with precise control systems to ensure that the copper foil is wound neatly and consistently, preventing any defects or damages during the winding process.
Pickled and Washed Parts: Prior to and after electro-deposition, the copper foil undergoes a pickling and washing process to remove any unwanted impurities and ensure a clean surface. This is an essential step in the production of high-quality copper foil, as contaminants can affect the performance of the lithium-ion batteries.

3.Control System and Specifications
The control system in the Hongtian Technology Co., Ltd. electro-deposited copper foil machine is crucial for ensuring precision and high performance during the production process. The control system uses advanced technologies from Japan and Germany, specifically the Mitsubishi and Lenz systems, which are known for their precision, fast response times, and high accuracy. These systems ensure that the copper foil is produced consistently, with high quality and minimal errors.
Mitsubishi/Lenz/Siemens Control Systems: The machine uses cutting-edge control systems from Mitsubishi (Japan) or Lenz (Germany), allowing for precise and rapid responses to production variables. These systems ensure that the copper foil production process is tightly controlled and that any necessary adjustments are made quickly and efficiently.
Tension Control System: The Hongtian Technology Co., Ltd. copper foil machine features a Mitsubishi tension control system that provides precise control over the tension of the foil. This system allows for an accuracy of ±0.3 kg, ensuring that the copper foil is produced at the correct tension, which is essential for maintaining uniform thickness and preventing defects.
Temperature and Drying Control: The oven and wind south drying cooling system is equipped with precise temperature control capabilities. The system maintains an accuracy of ±2°C, ensuring that the copper foil is dried and cooled efficiently without any temperature fluctuations that could affect the foil’s quality. The OMRON fan system offers stepless speed regulation for optimal air volume control.
Production Flexibility: The Hongtian Technology Co., Ltd. copper foil machine can be adjusted to meet different production requirements, including foil thickness, line speed, and winding diameter. The line speed ranges from 0 to 20M/min, providing flexibility to match different production demands. The machine can produce copper foil in widths from 1000mm to 2000mm, making it suitable for various applications in the lithium battery industry.
