The Corrugated Slitter Blade is precision-engineered from ultra-fine tungsten carbide and cobalt powders, sintered to form a high-performance cutting tool optimized for the carton manufacturing industry. It is the premier choice for cleanly and accurately slitting corrugated cardboard (3/5/7-ply). Its ultra-specular finish, with a maximum surface roughness of 0.025μm, minimizes material adhesion, ensuring cleaner and more precise cuts.
Designed for durability, the Corrugated Slitting Knife excels in demanding environments, offering enhanced strength and resistance to damage during operation. Manufactured using advanced, high-precision m-class equipment, it achieves exceptional flatness, preventing edge collapse during cutting and meeting the rigorous demands of various cardboard slitting applications.
Corrugated Cardboard Slitter Circular Knives
Slitter knives are crafted from materials with an ultra-fine-grained microstructure, ensuring exceptional edge sharpness. Designed for high-speed operations, they offer superior shear strength and precisely engineered bevels, delivering clean, burr-free, razor-sharp cuts with consistent accuracy.
