Copper Foil Slitting Blade for Lithium Battery Electrode Plate Cutting

The slitting of coated aluminum and copper foil used in Lithium Battery Production requires highly precision circular slitting blades. The blades’ production need to follow micron level tolerances, which is challenging for most of knife manufacturers. With more than 20 years’ experience, we can take care of the slitting blades’ outer diameter, inner diameter, thickness, concentricity, flatness and other parameters under strict control within the industry’s standards, or even surpassing the standards!
