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!
