In the modern industrial landscape, 18 inch disc blades represent a critical component for large-scale material processing, heavy-duty agriculture, and specialized industrial slitting. As manufacturing sectors shift toward high-speed automation, the demand for blades that maintain edge integrity under extreme thermal and mechanical stress has skyrocketed.
The global market for these precision components is currently driven by the expansion of the circular economy (recycling), the rise of lithium-ion battery production, and the modernization of infrastructure. Leading enterprises in Europe, North America, and Southeast Asia are increasingly moving away from traditional steel blades toward Tungsten Carbide and TiCN-based cermet materials to reduce downtime and increase output efficiency.
Why do global buyers choose Shen Gong?
Years of R&D Expertise
Certified Quality Systems
In-house RTP Powder Production
Established in 1998 in Chengdu, Sichuan, Shen Gong has evolved from a specialized workshop into a National High-Tech Enterprise. We occupy a unique position as a leading global manufacturer for WC-based cemented carbide and TiCN-based cermet industrial knives.
Our expertise spans the entire value chain, from raw material RTP powder formulation to the final high-precision grinding of finished blades. This vertical integration ensures that every 18 inch disc blade or slitting knife leaving our factory meets the most rigorous international standards.
Powerful R&D team for custom slitting solutions.
Stability across batches with ISO quality tracking.
Strategic partnerships for worldwide fast delivery.
High-toughness carbide for pelletizing and waste shredding under high impact.
