Leading the industry with high-precision cutting solutions for recycling, metal, and fiber sectors.
The global demand for high-performance granulator knives and pelletizing blades has reached an all-time high, driven by the explosive growth of the circular economy and the plastic recycling industry. In regions like Europe and North America, stringent environmental regulations have mandated higher recycled content in consumer goods, necessitating advanced machinery that can process waste materials with high efficiency.
Today, the industry is transitioning from standard tool steels to Tungsten Carbide and TiCN-based cermets. These materials offer the hardness and wear resistance required to withstand the abrasive nature of contaminated post-consumer plastics. As a leading manufacturer, SHEN GONG observes that global procurement teams are no longer just looking for "blades"—they are looking for comprehensive cutting solutions that reduce machine downtime and maximize throughput.
In the localized context, manufacturing hubs in Southeast Asia (such as Vietnam and Thailand) are rapidly upgrading their pelletizing lines, while the German and Japanese automotive sectors continue to demand the highest precision for specialized rubber and fiber components. This global landscape requires a manufacturer who understands both the micro-science of materials and the macro-needs of industrial production.
Sichuan Shen Gong Carbide Knives Co., Ltd. was established in 1998 in Chengdu, China. As a national high-tech enterprise, we have spent over two decades specializing in the research, development, and manufacturing of cemented carbide industrial knives.
What sets us apart is our complete production chain. Unlike many factories that simply grind purchased blanks, Shen Gong boasts full lines for WC-based cemented carbide and TiCN-based cermet. This covers the entire process from RTP (Ready-to-Press) powder formulation to the final precision-ground product. Our philosophy is simple: "Make Sharp Edge Always in Reach."
Learn More About UsThe modern industrial world requires knives that can handle diverse materials. Here is how SHEN GONG serves the global market.
Our high-toughness carbide materials are specifically engineered for pelletizing knives in virgin plastic production and shredder blades for recycling plants. Trend: Increase in high-toughness requirements to handle mixed waste.
SHEN GONG is a pioneer in China for precision slitting knives used in lithium electrode production. Our mirror-finish edges prevent material sticking, a critical factor for battery safety and efficiency.
As the world's largest manufacturer of corrugated slitter scorer knives, we provide the longevity needed for high-speed automated packaging lines.
Precision is life. We manufacture ultra-high-precision medical tungsten carbide blades with micron-level tolerances for surgical instruments.
From meat cutting to nut grinding, our food-grade carbide blades offer superior hygiene and edge retention compared to stainless steel.
1. Complete Material Control: Many manufacturers buy pre-made carbide blanks. At SHEN GONG, we start with the powder. By controlling the RTP powder making process, we can customize the grain size and cobalt content to create the perfect balance of hardness and toughness for specific granulator applications.
2. R&D Capabilities: We aren't just a factory; we are a solution provider. Our vision statement focuses on "Excellence and Determination." We provide geometric shape analysis and material properties testing to help our clients solve complex cutting failures.
3. Advanced Sintering Technology: Our investment in vacuum sintering and HIP (Hot Isostatic Pressing) technology ensures that every blade is 100% dense, eliminating micro-porosity that leads to premature blade failure in industrial granulators.
4. Global Logistics & OEM: Based in Chengdu, we leverage a robust supply chain to offer competitive pricing without sacrificing the quality that German or Japanese competitors offer. Our OEM service allows global brands to receive ISO-standard products under their own labels.
5. Sustainability: We offer recycling and re-sharpening services for used carbide knives. "Cherishing the finite, creating the infinite" is our mantra for a greener planet.
