In the modern manufacturing era, the demand for precision is no longer a luxury but a fundamental requirement. Bottom Slitter Knives, often referred to as the foundation of the shear slitting process, play a critical role in industries ranging from paper and packaging to high-tech energy storage like Lithium-ion batteries. As a leading manufacturer, Sichuan Shen Gong Carbide Knives Co., Ltd. has observed a significant shift in the global industrial landscape.
The global market for slitting tools is expanding rapidly. With the rise of e-commerce, the corrugated packaging industry has seen unprecedented growth, driving the need for ultra-durable slitter scorer knives. Simultaneously, the green energy transition has made Li-ion battery electrode slitting one of the most demanding sectors, requiring mirror-finish edges and zero-notch precision.
We are entering the age of "Smart Slitting." Today’s bottom slitter knives are no longer just pieces of metal; they are engineered components with optimized Tungsten Carbide (WC) microstructures. The trend is moving toward sub-micron grain sizes and PVD coatings that reduce friction, heat buildup, and dust generation, ensuring a cleaner cut and longer tool life.
International buyers from Europe, North America, and Southeast Asia are shifting their focus from "Initial Purchase Cost" to "Total Cost of Ownership." This means reliability, the frequency of regrinding, and the consistency of the slit edge are the primary factors in procurement decisions. Shen Gong addresses these needs by providing batch-to-batch stability through our integrated RTP powder production.
Established in 1998, Sichuan Shen Gong Carbide Knives Co., Ltd. has evolved from a specialized workshop into a global powerhouse in the carbide tool industry. Our headquarters in Chengdu, China, serves as a hub for innovation, where we manage the entire production cycle—from raw material powder preparation to the final precision grinding of finished blades.
Our status as a National High-Tech Enterprise is backed by over 20 years of research and development. We don't just sell knives; we provide slitting solutions. Whether it's analyzing the geometric properties of a blade for a client in Germany or providing customized carbide grades for a non-woven manufacturer in Japan, our expertise ensures that "Sharp edges are always in reach."
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. This vertical integration allows us to guarantee the highest quality standards at every step.

The efficiency of any slitting machine—be it a rewinder, a converter, or a specialized battery production line—depends heavily on the synchronization between the top and bottom knives. Bottom Slitter Knives act as the anvil in the shear cutting process. They must maintain a perfectly flat surface and a crisp edge to create the "pinch point" necessary for a clean, burr-free slit.
While many suppliers use standard tool steel, Shen Gong specializes in Cemented Carbide. Why? Carbide offers a hardness and wear resistance that is 10 to 20 times higher than traditional steel. This means fewer blade changes, less downtime, and a more consistent product quality over long production runs. Our proprietary WC-based materials are specifically sintered to withstand the high-impact environments of corrugated board cutting while maintaining the razor-sharp precision needed for 0.005mm metal foils.
Choosing a Chinese manufacturer like Shen Gong offers a unique blend of Scale, Speed, and Sophistication. China is currently the world's largest consumer and producer of industrial tools, which has allowed us to invest in cutting-edge machinery that smaller regional suppliers simply cannot afford. Furthermore, our proximity to the raw material supply chain for tungsten allows us to offer premium products at a highly competitive price point without compromising on the E-E-A-T principles our customers expect.
Every industrial application has its own set of challenges—be it dust control in paper mills or anti-adhesion in packaging plants. Shen Gong provides specialized treatments, including PVD coatings and mirror-polishing, to solve these localized problems. Our sales team offers multilingual support, ensuring that technical specifications are never lost in translation.
