2. Information Gain: Why Advanced Materials Matter

Standard steel blades often fail under high-speed industrial slitting due to thermal expansion and rapid edge degradation. At Shen Gong, we focus on WC-based cemented carbide and TiCN-based cermet. Cermet tools offer an exceptionally low affinity with ferrous metals, which translates to a mirror-like surface finish during metal machining and paper slitting.

Technical Advantage: Our blades for lithium-ion battery electrodes are engineered with zero-notch mirror edges, preventing material adhesion—a common failure point in battery manufacturing.
