Explore our advanced engineered blades optimized for high-speed converters and precision manufacturing processes.
In today's highly automated, ultra-precision manufacturing landscapes, circular slitting blades function as the unsung heroes of process efficiency and quality control. From processing lithium-ion battery separator materials to converting massive outputs of corrugated cardboard, packaging, and non-woven chemical fibers, the demand for precision circular blades has evolved from standard-grade tool steels to advanced powder metallurgy materials. The primary driver behind this material paradigm shift is the critical need to reduce manufacturing downtime and prevent material defects caused by micro-chipping or thermal distortion.
Advanced WC-based (Tungsten Carbide) cemented carbide and TiCN-based (Titanium Carbonitride) cermets offer a combination of extreme hardness (up to 92 HRA) and fracture toughness. Unlike standard tool steels, which soften significantly under high-friction thermal load, cemented carbide maintains its sharp profile longer. By controlling grain-size distributions down to sub-micron levels, manufacturers like Sichuan Shen Gong Carbide Knives Co., Ltd. ensure that the cutting edge remains geometrically uniform and free of micro-voids. This results in burr-free cuts, significantly reducing dust levels in paper and foil applications.
Global procurement heads and engineering managers look beyond individual unit costs. They prioritize long-term Total Cost of Ownership (TCO). Procurement evaluation processes focus on the following key metrics:

Explore how our precision engineered cutting blades support operations across various global industries.
Shen Gong's high-toughness carbide materials are developed for producing pelletizing knives in plastic and rubber manufacturing, as well as shredding blades for waste recycling. They withstand physical impact while retaining edge geometry longer.
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 for meat cutting, sauce grinding and nut crushing processes. Using food-safe, high-purity carbide compositions that are resistant to organic acids and oxidation, minimizing material transfer.
Industrial knives and blades for medical device manufacturing, suture preparation, and surgical scalpels. Micro-precision sharpening minimizes tissue resistance and ensures burr-free cuts under cleanroom conditions.
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, eliminating thermal welding.
Shen Gong is the world’s largest manufacturer for 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. Features mirror-finish edge without notches to prevent sticking, and includes matching knife holders.
Shen Gong’s high-precision shear slitting knives (coil slitting knives) have been exported to Germany and Japan for an extended period. They are widely used in coil processing, specifically for silicon steel sheets and metal foils.
In the industrial manufacturing sector, the term "resilience" has transitioned from a buzzword to a critical procurement requirement. Shen Gong's manufacturing ecosystem demonstrates how integrating vertical production processes allows for consistent quality. Unlike factories that source ready-made carbide blanks of varying quality, Sichuan Shen Gong operates an integrated pipeline from Ready-To-Press (RTP) powder formulation down to finished sharpening operations.
Carbide formulation begins with high-purity Tungsten Carbide and Cobalt binders. Through our integrated RTP powder preparation processes, we optimize grain size distribution based on the target application: micro-grain for high toughness in pelletizing and crushing, and submicron-grain for high edge retention in film and metal slitting. Through automated hot-isostatic pressing (HIP) sintering, internal porosities are virtually eliminated, providing uniform material density and structure across production batches.
Sichuan Shen Gong Carbide Knives Co., Ltd. utilizes automated precision grinders to achieve close tolerances on geometric specifications. Thickness flatness is held to within ±0.001 mm, and axial runout is controlled to prevent blade oscillation at high speeds. Each blade undergoes ultrasonic flaw detection and optical micrograph checks to verify edge integrity. This level of quality control reduces mechanical vibration in conversion lines, leading to longer component life and cleaner slitting results.
Sichuan Shen Gong Carbide Knives Co., Ltd. was established in 1998. Located in Chengdu, southwest of 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.
Shen Gong operates production lines for WC-based cemented carbide and TiCN-based cermet for industrial knives and blades, covering the entire process from RTP powder preparation to finished products.
Striving For Excellence, Forging Ahead With Determination Since 1998.
Since 1998, SHEN GONG has grown from a small workshop with just a handful of employees and a few grinding machines into a comprehensive enterprise specializing in the research, production, and sales of Industrial Knives, now ISO9001 certified. Throughout our journey, we’ve held fast to one belief: to provide professional, reliable, and durable industrial knives for various industries.
