The corrugated slitter blades are used to cut corrugated paper. Slitting is an important process in the production of corrugated paper. When the blade is heat treated, we use a large-diameter vacuum quenching furnace, the heat treatment is uniform, and the blade hardness HRC: 53°-65°. Using CNC machining machinery, the blade adopts grinding process to make the blade precision higher. We are committed to selling China's most professional carbide corrugated knives. Compared with ordinary corrugated knives, our cemented carbide corrugated knives are made of ultra-fine tungsten carbide powder and cobalt powder. It has no burrs, no indentation, low cutting resistance, high wear resistance, and sharp cutting edges. The best choice for corrugated cardboard 3/5/7 layer cutting. Super mirror surface (maximum surface thickness of 0.025 microns) can prevent shredded glue from accumulating on the blade, thereby achieving faster and more precise cutting.
