Jinao high-precision mirror rolls and ceramic rolls are purpose-built for coating and drying processes in lithium-ion battery separator production, widely used in ceramic coating, PVDF coating, and other critical steps.

Our mirror rolls deliver exceptional surface finish and dimensional accuracy, ensuring uniform coating, precise thickness control, and superior surface flatness. The ceramic rolls offer excellent corrosion resistance, wear resistance, and thermal stability, no deformation, no adhesion, even under high temperatures, significantly improving yield and consistency.

With rigorous dynamic balance testing and full-dimensional inspection, Jinao rolls maintain stable operation at high speeds, effectively reducing separator stretching and wrinkling, and enhancing battery safety and energy density from the process level.

Choose Jinao for reliable, high-performance roll solutions that drive greater efficiency and quality in your separator production line.
