Our tough circular blades are specifically engineered for cutting lithium battery films with extreme precision. Utilizing solid tungsten carbide, these blades offer significantly higher durability compared to standard alternatives. Industry leaders in the battery sector rely on our production for clean, burr-free, and dust-free results.

The core advantage lies in our unique manufacturing process that enhances blade density and sharpness. Designed for 5μm+ precision slitting, our blades minimize edge defects and prevent sticking or peeling—making them ideal for wet/dry process separators in EV, ESS, and 3C batteries.

• ◈ Ultra-Dense Carbide Material: 92.5% tungsten content for exceptional wear resistance at high speeds (200+ m/min).
• ◈ Submicron Edge Control: Laser-polished edges prevent filamentation and dust accumulation.
• ◈ High Flatness: Tolerance ≤0.003mm ensures stable tension for ceramic-coated and PVDF separators.
• ◈ OEM Flexibility: Custom diameters, bore sizes, and HRC 90+ hardness to meet specific requirements.
• ◈ ISO 9001 Certified: Every batch undergoes rigorous testing for consistent quality.
