The global industrial landscape for disc blades and industrial slitting knives is undergoing a radical transformation. As manufacturing speeds increase and materials become more complex—from multi-layer corrugated cardboard to delicate lithium-ion battery foils—the demand for high-precision, long-lasting cutting tools has never been higher. Today, industrial factories are moving away from traditional tool steels towards Tungsten Carbide (WC) and TiCN-based Cermet materials. These materials offer the hardness and heat resistance required to maintain a sharp edge under continuous operation, reducing downtime and increasing productivity across the supply chain.
Factories are now utilizing sub-micron and nano-grain carbide structures to achieve extreme toughness without sacrificing hardness. This is critical for ultra-thin slitting in the electronics sector.
The massive expansion of the Li-ion battery market requires specialized disc blades that can cut electrodes without leaving burrs or notches, ensuring the safety and longevity of the batteries.
There is a growing trend toward "Regrind and Reuse." High-quality carbide manufacturers like Shen Gong now provide recycling and re-sharpening services to lower the total cost of ownership.
Sichuan Shen Gong Carbide Knives Co., Ltd. was established in 1998 in Chengdu, China. As a national high-tech enterprise, we have specialized in the research, development, and manufacturing of cemented carbide industrial knives and blades for more than 20 years.
Our facility boasts complete production lines for WC-based cemented carbide and TiCN-based cermet, covering the entire process from RTP powder making to finished products. This vertical integration allows us to control quality at every micro-level, ensuring that "MAKE SHARP EDGE ALWAYS IN REACH" is more than just a slogan—it's our manufacturing standard.
From a small workshop to an ISO9001-certified global leader, our journey is defined by a commitment to providing professional, reliable, and durable industrial knives for over 10 different sectors.
Engineered for high-speed synthetic fiber lines, ensuring clean cuts with minimal friction heat.
High-precision blades for metal sheet processing, exported to top-tier clients in Germany and Japan.
Shen Gong is the world’s largest manufacturer for these knives, serving the global packaging industry.
Featuring a mirror-finish edge with zero notches to prevent material sticking at the cutting tip.
Optimized for paper and film rewinding systems, providing unmatched durability.
Procurement managers globally face the challenge of balancing tool life with initial cost. As a Chinese factory, Shen Gong offers a distinct advantage: high-performance carbide at a fraction of the cost of European brands, without compromising on precision. Whether it is a European packaging plant needing 20% longer tool life or a Southeast Asian rubber facility looking for high-toughness pelletizing knives, our localized solutions fit the specific machine requirements of any region.
We provide specialized treatments such as anti-adhesion and dust suppression for knives used in high-volume printing and packaging lines. This is vital for maintaining the aesthetics of the final product while keeping machines clean.
Our stainless-grade carbide blades for meat cutting, sauce grinding, and nut crushing are designed to meet food safety standards while providing the extreme hardness required to crush hard ingredients without wearing out.
Razor blades for synthetic fibers deliver superior performance due to their exceptional edge sharpness and symmetry. In chemical fiber plants, where speed is everything, these blades ensure zero downtime.
Production is carried out in accordance with the ISO quality system. Simply provide your samples, and we do the rest.
