Explore our top-tier tungsten carbide and cermet blades engineered for zero-defect slitting, high-wear resistance, and extended tool life.
Understanding material microstructures, wear dynamics, and precision grinding tolerances in modern automated manufacturing environments.
Modern high-speed industrial converting processes require cutting tools capable of maintaining razor-sharp cutting edges under intense friction and mechanical stress. Cemented carbide blades manufactured by Sichuan Shen Gong leverage sub-micron tungsten carbide (WC) grain sizes bound with optimized cobalt (Co) matrix ratios. This precise equilibrium delivers ultra-high hardness (up to HRA 93.5 / HV 1800) alongside superior fracture toughness (K1C), preventing premature edge micro-chipping during ultra-thin film slitting or heavy-duty cardboard scoring.
For metal finishing and clean-shear slitting of ferrous alloys, titanium carbonitride (TiCN) based cermets represent the pinnacle of material science. Cermet blades exhibit exceptionally low chemical affinity toward steel, preventing material build-up (BUE) on the blade tip. This ensures mirror-like cut edge surface finishes, minimal burr formation, and lower thermal oxidation during continuous high-speed rotation, making cermet tools ideal for high-precision finishing operations.
| Material Classification | Hardness (HRA / HV) | Fracture Toughness (MPa·m¹/²) | Primary Application Spectrum | Key Performance Advantage |
|---|---|---|---|---|
| Sub-Micron WC-Co | 91.5 – 93.5 HRA | 9.5 – 11.0 | Li-Ion Electrode, Film Slitting, Paper Converting | Maximum edge retention & zero-notch profile |
| Coarse Grain WC-Co | 88.0 – 90.5 HRA | 12.5 – 15.0 | Plastic Pelletizing, Waste Shredding, Rubber Shearing | Exceptional impact resistance against shocks |
| TiCN Cermet Matrix | 92.0 – 94.0 HRA | 7.5 – 9.0 | Metal Lathe Turning, Ferrous Coil Slitting | Ultra-low affinity, mirror cut surface finish |
| PVD Coated Carbide | HV 2800 – 3200 (Coating) | 10.0 – 11.5 | Corrugated Board Slitting & Scoring | Frictionless feed, heat & adhesion resistance |
Carbide blades engineered for a comprehensive spectrum of industrial slitting and shearing applications.
MAKE SHARP EDGE ALWAYS IN REACH — Over 25 Years of Technical Supremacy in Industrial Blade Manufacturing
Sichuan Shen Gong Carbide Knives Co., Ltd. was established in 1998 in Chengdu, Sichuan Province, China. As a national high-tech enterprise, Shen Gong specializes in the integrated research, development, metallurgical formulation, precision grinding, and global sales of tungsten carbide and cermet industrial blades.
Unlike standard secondary machining shops, Shen Gong operates complete in-house production lines for both WC-based cemented carbide and TiCN-based cermet. Our operations encompass the entire metallurgical sequence: from Ready-To-Press (RTP) powder synthesis, high-pressure hydraulic compaction, and Hot Isostatic Pressing (HIP) sintering to ultra-precision CNC grinding (achieving tolerances down to ±0.001mm) and automated optical inspection.
Empowering Tier-1 Global OEMs with Unmatched Raw Material Access, Vertically Integrated Manufacturing, and Rapid Delivery Safeguards.
China commands over 80% of global primary tungsten reserves and processing capacity. Operating within this robust ecosystem, Shen Gong secures pristine APT (Ammonium Paratungstate) and raw cobalt powders directly from audited domestic refiners. This upstream integration protects our international partners from unpredictable raw material price spikes and global supply chain disruptions.
By formulating our own Ready-To-Press (RTP) powders with custom grain-growth inhibitors (such as Cr3C2 and VC), we tailor material microstructures specifically for target cutting conditions—be it high-impact shredding or ultra-sharp film razor slitting. In-house spray drying towers guarantee homogeneous powder density and consistent batch-to-batch shrinkage.
High-capacity automated sintering furnaces and multi-axis CNC grinding arrays enable high-volume batch production with minimal labor overhead. This operational scale allows us to provide OEM premium-grade tooling at a fraction of Western European or Japanese replacement costs, delivering immediate ROI to machinery builders and converting plants worldwide.

Pioneering tomorrow’s smart tooling solutions through nanostructured coatings, automated quality inspection, and sustainable circular production.
Our ongoing material research focuses on depositing ultra-dense Physical Vapor Deposition (PVD) coatings—such as AlTiN, Diamond-Like Carbon (DLC), and CrN—onto tungsten carbide substrates. These nanostructured atomic layers reduce coefficient of friction to below 0.1, preventing thermal heat buildup during ultra-high-speed rewinding operations.
Shen Gong integrates automated 3D laser scanning and AI-assisted vision systems directly into the grinding line. Every blade's concentricity, radial runout (< 0.002mm), and bevel geometry are digitally mapped in real-time, eliminating human verification error and guaranteeing absolute physical perfection across OEM product runs.
Addressing global decarbonization goals, Shen Gong is expanding its spent carbide recycling infrastructure. By chemically extracting virgin-grade tungsten and cobalt from worn industrial knives, we reduce carbon emissions by over 60% compared to primary ore mining, giving converting plants a verified green procurement channel.
