Product Principle and Applications

,

Our advanced measurement system offers both wet and dry thickness assessments for foil and electrode materials. Developed by leading China suppliers, this system utilizes a specially engineered motion control mechanism that ensures precise tension control within ±1N, providing enhanced stability for the foil even during high-speed operations. At our factory, we prioritize micron-level precision with a closed-loop adjustment mechanism that maintains the optimal gap between the coating nozzle and the back roller,
, We guarantee the lateral wind speed uniformity of each nozzle remains within ±1.5%, while the wind speed consistency across all ovens is maintained within ±3%. Furthermore, our temperature uniformity in each oven achieves an impressive stability level of ±1.5%, making our product ideal for high-quality manufacturing processes.
