Tungsten Carbide Top Knife for Lithium Battery Slitting

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!
