Our premium selection of industrial blades designed for unparalleled accuracy and extreme longevity.
The global transition toward electrification has catapulted the demand for high-performance lithium-ion batteries to unprecedented heights. At the heart of this technological revolution lies Electrode Slittingβa critical manufacturing process where wide rolls of coated anode and cathode materials are precision-cut into narrow strips. This stage is widely considered the most technically challenging mechanical process in battery production.
Currently, the market is driven by the expansion of "Gigafactories" across Asia, Europe, and North America. As battery manufacturers strive for higher energy density and faster charging times, the tolerance for error in electrode slitting has shrunk to the sub-micron level. The global industrial status reflects a shift from traditional steel blades to ultra-hard tungsten carbide materials, capable of maintaining sharp edges under the abrasive stress of active battery materials like NCM (Nickel Cobalt Manganese) and LFP (Lithium Iron Phosphate).
Established in 1998 in Chengdu, China, Shen Gong is a national high-tech enterprise specializing in the R&D, manufacturing, and sales of cemented carbide industrial knives. With over two decades of expertise, we boast complete production lines for WC-based cemented carbide and TiCN-based cermet, covering the entire process from RTP powder production to the finished, mirror-polished edge.
Our commitment to "Striving For Excellence" has led us to become a cornerstone supplier for the global battery, packaging, and metal machining industries.
View Corporate ProfileModern slitting lines now operate at speeds exceeding 100 meters per minute. This requires knives with exceptional thermal stability and wear resistance to prevent edge deformation during continuous high-speed friction.
The primary trend in electrode slitting is the elimination of "burrs" and "active material shedding." Even a microscopic burr can pierce the separator, leading to internal short circuits and thermal runaway in batteries.
Procurement departments are increasingly looking for suppliers who offer regrinding and recycling services. Tungsten carbide is a finite resource; extending the life of a blade through precision sharpening is both an economic and environmental mandate.
Global enterprises, particularly Tier 1 battery suppliers for the EV industry, have stringent procurement criteria. They demand more than just a component; they require a partner with Technical Authoritativeness (E-E-A-T). Key requirements include:
Based in China, the world's hub for tungsten resources, we control the entire process from RTP powder to finished blades. This ensures cost-efficiency without compromising on high-purity material quality.
Shen Gong was the first company in China to develop precision slitting knives specifically for lithium-ion battery electrodes. Our R&D team continuously evolves designs to match the latest dry-coating and solid-state battery technologies.
Through strategic partnerships with world-renowned couriers, we ensure fast, reliable delivery to Gigafactories in Germany, the USA, Japan, and beyond, minimizing downtime for our clients.
We don't just sell knives; we provide slitting solutions. Provide us with your samples or machine specs, and our engineers will design a blade that optimizes your specific production line.
Our Li-ion battery electrode knives feature a mirror-finish edge with zero notches. This "Super-Finish" prevents material sticking, which is the leading cause of downtime in high-volume production.
Our professional sales team offers multilingual services, ensuring clear communication and a response to any technical inquiry within 24 hours.
First in China to develop electrode precision slitting knives. Mirror-finish, no-notch edges.
World's largest manufacturer for corrugated slitter scorer knives and grinding parts.
High-precision coil slitting knives exported to Germany and Japan for silicon steel processing.
Anti-adhesion and corrosion-resistant treatments for maximum durability.
In European Gigafactories, where environmental regulations are extremely strict, Shen Gongβs recycling and re-sharpening services provide a localized "green" benefit. Our knives are designed to withstand the rigors of multi-layer corrugated cardboard cutting in massive packaging hubs in Poland and Germany, increasing tool life by up to 20%.
In North American EV Hubs (such as Tesla's Gigafactories or the Ford BlueOval City), the demand is focused on Burr-Free quality for high-nickel cathode materials. Shen Gong's vacuum-sintered carbide blades provide the necessary hardness (HRA 90+) to ensure that edges remain sharp even when cutting the most abrasive coatings.
