The global demand for 18 Inch Notched Disc Blades has transitioned from basic carbon steel to high-performance alloy and carbide-enhanced materials. As modern agriculture and industrial waste management move toward "zero-downtime" operations, the durability of these blades determines the economic efficiency of large-scale projects.
Technological trends are shifting toward precision notched geometries. In agricultural applications, notched blades are essential for superior soil penetration and residue management. In industrial sectors, similar circular notched configurations are used for high-toughness material shredding and recycling.
OEMs and distributors in North America, Europe, and Southeast Asia are increasingly seeking manufacturers that offer Batch Consistency and ISO9001 certified quality. The focus has moved from "lowest price" to "lowest total cost of ownership," favoring blades that last 20-30% longer than traditional options.
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.
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. Our expertise in high-precision metallurgy allows us to produce blades that withstand the most rigorous industrial environments, including the demanding specifications required for 18 Inch Notched Disc Blades used in heavy-duty machinery.

Years Experience
Certified Quality
Shen Gong is the worldโs largest manufacturer for corrugated slitter scorer knives. We provide resharpening grinding wheels and cross-cut blades for global packaging plants.
As the first company in China to develop precision slitting knives for battery electrodes, our blades feature a mirror-finish edge with zero notches for high-speed separation.
High-toughness carbide materials specifically developed for pelletizing knives and shredding blades in waste recycling and plastic manufacturing.
For 18 Inch Notched Disc Blades, localized application is key. Whether dealing with the heavy clay of the Midwest US or the sandy soils of Western Australia, our engineering team adjusts the Carbide Grain Size to balance hardness and impact resistance, preventing edge chipping.
Located in the industrial hub of Sichuan, China, we leverage a complete supply chain. Unlike "trading companies," we control the RTP Powder production, ensuring that every batch of tungsten carbide used in our notched blades meets extreme metallurgical standards.
Our high-precision shear slitting knives have been exported to Germany and Japan for decades. This experience with top-tier engineering standards allows us to manufacture agricultural and industrial blades that compete with any global brand.
Production is carried out in accordance with the ISO quality system. Simply provide your samples, we do the rest.
Rooted in knives, but far beyond. Our R&D team provides complete industrial cutting and slitting solutions.
For a greener planet, Shen Gong offers re-sharpening and recycling services for used carbide knives.
