In the modern industrial landscape, high-quality circle cutting tools are more than just consumables; they are critical components that determine the efficiency of automated production lines. From the high-speed slitting of lithium-ion battery electrodes to the precision trimming of medical-grade textiles, these tools must withstand extreme friction and heat while maintaining a microscopic edge sharpness. As a leading supplier and factory, Shen Gong understands that even a micron-level deviation can result in costly material waste or product failure.
The industrial tool sector is undergoing a rapid digital transformation. The integration of AI-driven manufacturing and IoT monitoring allows factories to predict tool wear before it impacts quality. Current trends highlight a shift toward ultra-fine grain tungsten carbide and advanced ceramic materials that offer up to 5x the lifespan of traditional steel. We are seeing a massive surge in demand for tools that support 24/7 "lights-out" manufacturing, requiring extreme consistency between production batches.
Sichuan Shen Gong Carbide Knives Co., Ltd. was established in 1998. Located in southwest of China, Chengdu, 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 boasts complete production lines for WC-based cemented carbide and TiCN-based cermet for industrial knives and blades, covering the entire process from RTP powder making to finished product. Since our inception, we have grown from a small workshop into a comprehensive enterprise that is a global leader in the corrugated industry and lithium-ion battery slitting technology.
Since 1998, SHEN GONG has grown into a comprehensive enterprise specializing in the research, production, and sales of Industrial Knives. Throughout our journey, we’ve held fast to one belief: to provide professional, reliable, and durable industrial knives for various industries. Striving For Excellence, Forging Ahead With Determination.
Tailored solutions for every cutting challenge
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 corrugated industry. Our ATS (Anti-Sticking) technology ensures clean cuts and minimal downtime.
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, effectively preventing material sticking at the cutting tip during slitting.
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.
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.
Our high-precision shear slitting knives are widely used in the coil processing industry, particularly in the slitting of silicon steel sheets for motor manufacturing and non-ferrous metal foils. Long-term exports to Germany and Japan prove our quality.
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.
For procurement managers in Europe, North America, and Southeast Asia, the primary concern is the Total Cost of Ownership (TCO). While local suppliers might offer proximity, a Chinese factory like Shen Gong provides a unique advantage through vertical integration. By manufacturing our own RTP (Ready-to-Press) powder, we control the purity of the carbide, which directly translates to a 20-30% increase in tool life as evidenced by our partners in European packaging plants.
