Understanding the evolution of high-precision cutting technology in modern manufacturing.
The global industrial landscape is undergoing a radical shift toward automation and ultra-high precision. Circular Slitter Blades have become the unsung heroes of this revolution. From the ultra-thin films used in electric vehicle (EV) batteries to the high-speed processing of corrugated packaging, the demand for blades that offer longevity, microscopic edge precision, and minimal downtime is at an all-time high.
Today, the commercial value of slitting technology is measured by "Total Cost of Ownership." Modern enterprises no longer look for the cheapest blade; they seek suppliers who can provide tungsten carbide and TiCN-based cermet materials that extend tool life by 200-500% compared to traditional steel. As a leading manufacturer based in China, Sichuan Shen Gong Carbide Knives Co., Ltd. is at the forefront of this shift, providing global solutions that balance Chinese cost-efficiency with aerospace-grade precision.

In-house Production
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 more than 20 years.
Unlike many trading firms, Shen Gong boasts complete production lines for WC-based cemented carbide and TiCN-based cermet. This covers the entire vertical process from RTP (Ready-to-Press) powder making to precision grinding of the finished product. Our 20-year journey from a small workshop to a global leader underscores our commitment to excellence.
Customized slitting solutions for diverse global industries.
Shen Gong is the first in China to develop precision slitting knives for lithium-ion battery electrodes. Featuring mirror-finish edges with zero notches to prevent material sticking and burrs during high-speed slitting.
As the world’s largest manufacturer for corrugated slitter scorer knives, we provide complete solutions including resharpening grinding wheels and cross-cut blades for the packaging industry.
High-precision shear slitting knives exported to Germany and Japan for coil processing, motor manufacturing (silicon steel sheets), and non-ferrous metal foils.
High-toughness carbide materials developed specifically for pelletizing knives and shredding blades in the waste recycling and polymer manufacturing sectors.
Razor blades designed for synthetic fibers and non-woven materials, delivering superior edge sharpness and symmetry for clean, lint-free cuts.
TiCN-based cermet cutting tools for steel part finish machining. Low affinity with ferrous metals ensures an exceptionally smooth surface finish.
Industrial knives and blades for meat cutting, sauce grinding, and nut crushing. Manufactured with food-safe standards and high corrosion resistance.
Specialized high-precision knives for medical device manufacturing, ensuring the strict tolerances and cleanliness required for the healthcare sector.
Advanced anti-adhesion and dust suppression treatments for blades used in high-speed paper slitting and label printing applications.
Strict ISO quality systems ensure batch-to-batch stability. Simply provide samples, and we handle the metallurgy, design, and mass production.
Our R&D team doesn't just sell blades; we solve slitting challenges. We analyze your material and machine speed to recommend the perfect grade.
Sustainability in action. We offer re-sharpening and recycling services for used carbide knives to help reduce your environmental footprint.
Multi-lingual sales team responding to global inquiries within 24 hours. Communication is seamless regardless of your time zone.
Strategic partnerships with major couriers ensure your production line never stops. Fast shipping to Europe, Americas, and SE Asia.
Whether it's geometric shapes or material properties, we provide detailed analytical results to guarantee performance before shipping.
The global push for EVs has created a massive demand for ultra-precise slitting of lithium-ion battery separators and electrode foils. These materials are sensitive to heat and friction. The trend is moving toward ETaC-3 coated blades and mirror-finished carbide that minimizes friction and prevents "edge curling."
Smart factories require blades with predictable lifespans. Modern procurement managers are looking for "Smart Cutting" components. By utilizing Shen Gong’s consistent carbide grades, manufacturers can program automated blade changes with precision, reducing unplanned downtime.
Tungsten and Cobalt are finite resources. The trend of "Knives Recycling" is growing. Shen Gong’s initiative to re-sharpen and recycle used tools is not just eco-friendly; it significantly reduces the long-term material cost for our industrial partners.
Global enterprises are moving away from "general purpose" blades. Whether it's a paper mill in Scandinavia or a battery plant in South Carolina, the demand is for localized application-specific geometry. Shen Gong's ability to customize blade angles to the micron level is why we maintain a high retention rate with global OEMs.
