Tungsten Carbide Circular Slitting Knife HRC92-95 for Lithium Battery Electrode
In recent years, the rapid development of the new energy industry has led to increased production of lithium batteries, creating significant demand for high-quality lithium battery blades. As a key player in this sector, we specialize in manufacturing precision cutting tools for lithium battery production, including pole slice cutting, diaphragm cutting, and non-ferrous metal cutting applications.
Our lithium battery electrode slice slitters are manufactured from cemented carbide powder through pressing, sintering, and fine grinding processes. These blades feature high wear resistance and anti-adhesion properties, specifically designed to address common cutting challenges such as sticking, dust accumulation, burrs, knife back prints, wavy edges, and color differences.
Each blade undergoes 500x magnification inspection to ensure flawless edges. Our years of experience in cemented carbide tool production, combined with strict quality control and unique edge precision machining technology, guarantee superior performance and safety in lithium battery manufacturing applications.
- Hard alloy tungsten steel material with exceptional wear resistance
- High-precision cutting edge with thickness accuracy up to 3 microns
- Extended service life with cutting length up to 20,000 meters
- Excellent blade consistency with minimal burr formation
- Designed for cutting lithium battery pole pieces, ceramic diaphragms, copper foil, and aluminum foil
- Available in matched upper and lower knife sets
