Explore our core custom-manufactured circular cutter blades and specialized grinding tools engineered for global manufacturers.
In high-speed industrial slitting, cutting, and trimming, the selection of the cutting tool material and geometry dictates the overall efficiency, stability, and product quality of your assembly lines. As a specialized manufacturer of custom circular cutter blades, Sichuan Shen Gong Carbide Knives Co., Ltd. blends cutting-edge powder metallurgy with micro-grain precision grinding technology. We supply the global market with premium, high-wear-resistant circular blades tailored for complex converting operations.
Standard tool steels often fall short in high-cycle operations where friction, mechanical shock, and chemical exposure cause rapid edge degradation. By employing Sub-Micron and Ultra-Fine Grain Tungsten Carbide (WC-Co) along with Titanium Carbonitride (TiCN)-based Cermet, we achieve an optimal balance of hardness (measured up to 94 HRA) and fracture toughness. Our metallurgical process includes sinter-HIP (Hot Isostatic Pressing) technology to remove microscopic voids, increasing the material density and grain homogeneity. The result is a structural integrity that prevents micro-chipping, the leading cause of premature tool failure in lithium-ion battery electrode processing and corrugated card converting.
In industries like coil slitting and lithium electrode fabrication, edge burrs can ruin entire product batches. Thus, our circular cutter blades are manufactured with dimensional runout tolerances as tight as ±0.001mm. We control the axial and radial runout through ultra-precision CNC double-disc grinding and specialized mirror polishing. This minimizes tool vibration and eliminates metal dust generation, leading to cleaner cuts, prolonged blade life, and minimized mechanical down-time for your slitting systems.
Established in 1998 and located in Chengdu, 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 20 years.
We boast 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 preparation to the final finished product. This ensures full quality control, unmatched batch stability, and rapid response to customized tool requirements.
Carbide and cermet blades optimized for a wide range of industrial slitting applications worldwide.
Specifically formulated grades to combat heat generation and structural abrasion during high-speed synthetic fiber extrusion.
Perfect dimensional alignment and flatness for burr-free slitting of transformer silicon steel sheets and metal foils.
We are the world's largest manufacturer, providing long-lasting edge life and minimizing dust generation in packing facilities.
High impact toughness materials built to withstand heavy shocks in plastics, rubber, and waste recycling shredders.
Mirror-finish razor edges designed to slit thin plastics, stretch wraps, and laminates without pulling or deformation.
Zero-notch mirror edges preventing slurry build-up and keeping lithium battery slitting clean and efficient.
Designed with absolute concentricity and precise shear angle configuration to work in tandem with top cutters.
Circular profile cutters configured for clean severance of multi-material tubes and industrial filters.
Different regions have unique industrial setups. For instance, in European packaging hubs, high-capacity machinery demands extreme slitting speeds, rendering traditional steel knives obsolete within days. Here, our custom tungsten carbide blades achieve up to 20% improvement in tool life (backed by real-world factory metrics in Germany). In North American paper mills, our dust-suppression blade geometry prevents microscopic pulp fibers from clogging complex pneumatic holders. Meanwhile, in Asian lithium-ion gigafactories, we supply high-performance cermet profiles that withstand the abrasive nature of positive cathode coatings (LiCoO2, LiFePO4) and negative anode slurries.
The next generation of industrial slitting demands integration with Industry 4.0 systems. Our technical roadmap focuses on three main developments:
We configure blade micro-geometries and metallurgy based on the precise demands of your industry.
Shen Gong's high-toughness carbide materials are specially developed for producing pelletizing knives in plastic and rubber manufacturing, as well as shredding blades for waste recycling.
Razor blades designed for cutting synthetic fibers and non-woven materials deliver superior performance due to their exceptional edge sharpness, straightness, symmetry, and surface finish, resulting in better cutting performance.
Industrial knives and blades made from food-safe and corrosion-resistant alloys, specifically designed for meat cutting, sauce grinding, and nut crushing processes.
High-precision customized scalpels, cutting blades, and foil slicers designed under clean-room requirements for medical device manufacturing.
We provide TiCN-based cermet cutting tools for steel part semi-finish to finish machining. Very low affinity with ferrous metals results in an exceptionally smooth surface finish during machining.
Shen Gong is the world’s largest manufacturer of corrugated slitter scorer knives. Meanwhile, we provide resharpening grinding wheels, cross-cut blades, and other parts for the corrugated industry.
Shen Gong's advanced carbide material technology delivers exceptional durability, and we offer specialized treatments such as anti-adhesion, corrosion resistance, and dust suppression for knives used in these industries.
Shen Gong is the first company in China to develop precision slitting knives specifically designed for lithium-ion battery electrodes. The knives feature a mirror-finish edge with absolutely no notches, preventing material sticking at the cutting tip.
Shen Gong’s high-precision shear slitting knives (coil slitting knives) are exported to Germany and Japan. They are widely used in the coil processing industry, particularly in the slitting of silicon steel sheets for motor manufacturing.
In today's volatile economic environment, ensuring a stable supply of industrial consumables is key. Sichuan Shen Gong Carbide Knives Co., Ltd. utilizes regional geographical advantages. Chengdu sits near some of the world's most abundant reserves of raw tungsten deposits. This secures our supply chain starting from raw materials. By managing the full production flow internally—from Ready-to-Press (RTP) powder preparation, sintering, tooling design, mirror polishing, and quality checks—we eliminate middleman markups and reduce supply-side quality risks.
Our vertical integration ensures we are highly resilient against logistics shocks. Furthermore, we maintain strategic partnerships with global logistics hubs. This permits rapid air and sea shipping directly from Sichuan to manufacturing plants across North America, Europe, and the APAC region. This integrated model provides our clients with highly competitive pricing, stable lead times, and custom engineering support.
Our factory operates strictly under the ISO 9001:2015 Quality Management System. Every circular cutter blade leaves our facility with full traceability. We match every batch with an inspection report outlining density, hardness, bend strength, and dimensional tolerances. For chemical, packaging, and food-processing applications, our tungsten carbide grades comply with relevant FDA and REACH requirements. This facilitates direct compliance integration into our clients' local production lines.
