Principle and Application

,

● Comprehensive Measurement System: Our technology measures both wet and dry thickness of foils and electrodes, ensuring precise quality control;
● Innovatively Designed Motion Control System: Achieves tension control accuracy of ≤±1N, providing enhanced stability for foil during high-speed operations;
● Micron-Level Precision: Features a closed-loop adjustment mechanism that maintains optimal gaps between the coating nozzle and the back roller;
● Consistent Wind Speed: Each nozzle exhibits uniform lateral wind speed with a variation of ≤±1.5%, and each oven maintains wind speed uniformity of ≤±3%;
● Temperature Uniformity: Each individual oven maintains a temperature consistency of ≤±1.5%.
As a leading China suppliers and factory, we strive to deliver cutting-edge solutions for your manufacturing needs.
