Premium Carbide & Ceramic Industrial Cutting Tools Configured to Reduce Tool Downtime and Maximize Slitting Precision.
Established in 1998 in Chengdu, Sichuan (Southwest China), Shen Gong is a national high-tech enterprise specializing in the research, development, manufacturing, and sales of cemented carbide industrial knives and blades for over 25 years.
Shen Gong boasts complete production lines for WC-based cemented carbide and TiCN-based cermet for industrial knives and blades, covering the entire process from RTP (Ready-To-Press) powder manufacturing to high-precision finished products. By maintaining full control of the raw material formulation and processing, we ensure unmatched metallurgical uniformity and dimensional consistency.
Learn More About UsA comprehensive overview of material developments, grain-size optimizations, and surface treatments engineered for next-generation polymer processing.
Modern polymers contain abrasive fillers (glass fibers, calcium carbonate, and flame retardants) that rapidly degrade conventional steel blades. At Shen Gong, we leverage powder metallurgy to synthesize ultra-fine and nano-grained tungsten carbide (WC) combined with cobalt (Co) or nickel (Ni) binders. Our proprietary sintering processes minimize porosity and grain growth, resulting in cutting tools that maintain an optimized combination of high fracture toughness (K1c) and extreme hardness (HV10).
In addition to WC-Co formulations, our cermet (Titanium Carbonitride based) technology provides a highly stable cutting edge for operations where adhesive wear and chemical reactions are common. Our TiCN cermet profiles offer a extremely low affinity to ferrous metals, non-ferrous foils, and high-tack adhesive tapes, eliminating edge buildup during high-speed slitting.
Grain sizes under 0.8μm provide maximum hardness and edge retention, perfect for thin film slitting blades and high-speed rotary cutters.
Application of TiAlN, TiN, and DLC (Diamond-Like Carbon) coatings to reduce the coefficient of friction and thermal stress at the cutting edge.
Controlled edge radius preparation (honing) between 3μm and 12μm eliminates micro-chipping, ensuring a burr-free edge finish on PET/PE films.
Since 1998, SHEN GONG has grown from a small workshop with just a handful of employees and a few outdated grinding machines into a comprehensive enterprise specializing in the research, production, and sales of Industrial Knives, now ISO9001 certified. Striving For Excellence, Forging Ahead With Determination.

Explore ApplicationHow Shen Gong combines vertical integration, localized raw material access, and automated processing to guarantee consistent supply and competitive pricing.
In the global industrial tool sector, stability is the ultimate metric. Because Shen Gong controls the entire supply chain starting from Ready-To-Press (RTP) tungsten carbide powder, we insulate our international buyers from raw material volatility. Our location in Chengdu grants direct proximity to China's primary tungsten deposits, providing a stable supply of ultra-pure tungsten trioxide.
Our factory leverages Industry 4.0 automation, utilizing multi-axis CNC grinding machines, automated optical sorting equipment, and HIP (Hot Isostatic Pressing) sintering furnaces. This integration minimizes mechanical error margins, delivering cutting edges with straightness tolerances down to 0.002mm and thickness tolerances within ±0.001mm.
Streamlined customization workflows, compliance sheets, and green recycling initiatives for high-volume international OEMs.
Shen Gong serves tier-one manufacturing facilities across North America, Europe, and the APAC region. We recognize that industrial components must conform to strict local regulations. Every custom batch of carbide and ceramic cutting blades is traceable from the raw material lot to the final shipment. We supply comprehensive Material Test Reports (MTRs), REACH declaration statements, and RoHS compliance certificates upon request.
To mitigate logistics lead times, our logistics network provides end-to-end custom clearance integration and express courier partnerships (DHL, FedEx, UPS). This ensures that emergency replacement blades reach your facility within days, preventing costly production halts.
Environmental Responsibility: In line with ESG initiatives, Shen Gong offers a circular recycling program. Used carbide tools contain finite raw materials like Cobalt and Tungsten. We run localized reclamation programs, offering credit programs for recycling old blades, helping our partners achieve zero-waste manufacturing goals.
