Ultra-Precision Slitting

Engineered with premium tungsten carbide, blades deliver sub-micron precision (±0.001mm) for ultra-fine slitting applications. The ultra-dense material, combined with mirror-edge polishing (Ra ≤0.02μm), ensures burr-free cuts (<3μm) in lithium battery electrodes.

SURFACE TREATMENT

In addition to polishing, Shen Gong can provide other special surface treatments that offer benefits such as anti-stick, anti-corrosion, oxidation resistance, and increased surface hardness.

Custom Solutions

Material options: Tungsten carbide & specialty alloys

Edge customization: 27°-90° angles for optimized cutting performance

Diameter range: 15mm-400mm to fit your machine specifications

Seamless compatibility: Works with all major slitting equipment brands

Materials Manufacturing Technology

Utilizing 0.4~0.8 μm ultra-fine tungsten carbide effectively controls tip defects on precision blades, suppresses dust, and significantly enhances precision slitting performance, resulting in better cut quality.

High hardness brings excellent durability, with HRA hardness reaching up to 93.5.

The combination of good fracture toughness and flexural strength ensures more stable performance during blade use.

Industry Applications

Trusted by Top 3 Global Battery Manufacturers

Lithium Battery Electrode (Anode/Cathode) /Battery Separator (PP/PE/Ceramic Coated) / Copper/Aluminum Slitting

Burr-Free Cutting

Ultra-precision grinding technology minimizes edge burrs (<5μm), ensuring smooth electrode edges.

Dust & Particle Suppression

Anti-static coating reduces dust adhesion, improving cell assembly yield.

No Wavy Edges

Optimized blade geometry prevents material deformation, eliminating wavy edges.
