In the modern manufacturing era, Rotary Shear Blades have become the backbone of high-speed processing lines. From heavy-duty steel mills to high-precision lithium battery production, the demand for blades that can withstand extreme heat and friction while maintaining a microscopic edge is surging. Globally, the industry is shifting from traditional tool steel to Tungsten Carbide (WC) and Cermet (TiCN) based materials to achieve 10x longevity.
The global push for a circular economy has positioned rotary shredder knives at the forefront of the recycling industry. High-toughness carbide materials are now essential for processing plastics, rubber, and e-waste. This trend requires manufacturers to innovate blades that are not only hard but also resistant to impact, preventing catastrophic failures during the recycling of contaminated materials.
Modern procurement needs have evolved beyond just purchasing a product; global enterprises now look for "smart" solutions. This includes predictive maintenance through blade wear analysis and the use of specialized coatings (like anti-adhesion and corrosion resistance) to minimize downtime in automated slitting lines.
Established in 1998 in Chengdu, Sichuan, Shen Gong has spent over two decades pioneering the research, development, and manufacturing of cemented carbide industrial knives. As a national high-tech enterprise, we operate complete production lines—from RTP powder making to the finished high-precision blade.
Experience: 25+ years of specialized carbide expertise.
Quality: ISO9001 certified production and quality control.
Innovation: First in China to develop Li-ion electrode slitting knives.
Engineered for excellence across diverse manufacturing sectors.
Shen Gong is the first company in China to develop precision slitting knives specifically for lithium-ion battery electrodes. Featuring mirror-finish edges with no notches, these knives prevent material sticking and ensure clean cuts for EV battery safety.
As the world’s largest manufacturer for corrugated slitter scorer knives, we provide unrivaled durability for high-speed packaging lines, including resharpening wheels and cross-cut blades.
Our coil slitting knives are exported to Germany and Japan, serving the silicon steel sheet industry for motor manufacturing and non-ferrous metal foil processing with micron-level precision.
Utilizing high-toughness carbide, our shredding and pelletizing knives are designed to handle the abrasive nature of recycled materials, significantly reducing tool replacement frequency.
We provide TiCN-based cermet cutting tools for steel part semi-finish to finish machining. Low affinity with ferrous metals results in an exceptionally smooth surface finish.
Global buyers from Europe and North America often require bespoke geometries. At Shen Gong, we carry out production in strict accordance with the ISO quality system. Simply provide your samples or blueprints, and our RTP powder expertise allows us to match the exact material properties needed for your specific substrate.
While the initial cost is a factor, the real value lies in "Tool Life." Our European packaging clients have reported a 20% increase in tool life after switching to Shen Gong high-precision slitting blades. By reducing the frequency of knife changes, we help factories maximize their uptime and ROI.
Whether it’s geometric shapes or material properties, we provide reliable analytical results. For industries like food processing (meat cutting, sauce grinding) or medical device manufacturing, we offer specialized material grades that meet local regulatory and performance standards.
Cherishing the finite, creating the infinite. For a greener planet, Shen Gong offers re-sharpening and recycling services for used carbide knives, a service highly valued by eco-conscious procurement teams in the EU and beyond.
