Engineered for high-speed performance and burr-free precision.
In the modern industrial slitting and rewinding industry, Dusenbery shear knives have become the gold standard for precision. As global manufacturing pivots toward high-speed, automated production lines, the demand for high-performance shear slitting tools has surged. These knives are critical in processing everything from ultra-thin plastic films and lithium-ion battery electrodes to heavy-duty non-woven fabrics and corrugated paper.
The current global business landscape shows a significant trend: manufacturers are moving away from traditional tool steels towards Tungsten Carbide (WC) and Cermet (TiCN) materials. This shift is driven by the need for longer tool life, reduced downtime, and the "burr-free" edge quality required in high-tech sectors like electric vehicle (EV) battery production.
25+ Years of Mastery in Cemented Carbide Industrial Knives
Unlike many suppliers, Shen Gong manages the entire process—from RTP powder manufacturing to the final precision grinding. This ensures absolute consistency across every batch.
Our national high-tech enterprise status is backed by over 20 years of research in WC-based and TiCN-based materials, specifically optimized for slitting applications.
Quality is not an accident. Our production follows strict ISO protocols, ensuring that our knives meet the rigorous standards of the German and Japanese markets.

Delivery Network
The evolution of Dusenbery style shear slitting has been marked by the transition from manual setups to precision-engineered pneumatic knife holders and high-precision circular blades. In the North American and European markets, procurement managers are increasingly prioritizing "Cost per Cut" over the initial purchase price. This is where high-quality Chinese factories like Shen Gong provide a competitive edge.
Our role as a Dusenbery shear knife factory is to provide not just a product, but a solution that includes geometry analysis, material property testing, and quick-reply technical support.
Tailored solutions for every cutting challenge.
Since 1998, SHEN GONG has transformed from a small workshop into a global powerhouse. Our philosophy is simple: "Striving For Excellence, Forging Ahead With Determination."
