Core Process Advantages for New Energy Components
Compared with traditional stamping, rolling, and single laser processing, the dual-process collaborative mode fully meets the high-current, high-precision, high-reliability processing requirements of new energy components with stronger process adaptability:
-
Photochemical Etching Process: Adopts low-temperature, high-precision chemical corrosion technology to form ultra-thin metal foils (0.01mm-2.0mm) with complex patterns in one piece. The process is stress-free, ensuring no warping or deformation of the material. It can achieve a minimum line width/space of 0.05mm, ensuring the high current density and uniform conductivity of components such as current collectors and bipolar plates. No custom mold is required, enabling rapid prototyping and flexible production.
-
Precision Laser Cutting Process: Uses a high-power, ultra-fast fiber laser system to achieve cold cutting of various metal materials. The heat-affected zone is minimal, avoiding material performance degradation caused by thermal processing. It can achieve a cutting precision of ±0.01mm, meeting the high-precision assembly requirements of new energy components. The non-contact processing method ensures no mechanical stress or damage to the workpiece surface, suitable for cutting high-value, thin, and fragile materials.
