slitting blade

Precision in slitting is the difference between a high-quality roll and costly waste. TINVO’s slitting blades are engineered for high-speed, high-accuracy conversion of diverse materials, including metal foils, films, paper, and non-wovens. Our knives are designed to deliver a perfect “scissor-cut” or “crush-cut” action, ensuring burr-free edges and consistent strip widths.

• Elite Material Selection: We offer blades crafted from premium D2 (SKD11), M2 (HSS), and Tungsten Carbide. These materials provide the necessary hardness and thermal stability to maintain a razor-sharp edge during continuous, high-speed production runs.

• Micron-Level Precision: To eliminate cumulative errors in multi-blade setups, our circular slitter knives are manufactured to extreme tolerances . This ensures that each strip in your slitting line is uniform and dimensionally accurate.

• Mirror-Finish Surface Treatment: Our specialized grinding and lapping processes result in a mirror-like finish on the blade faces. This significantly reduces friction, prevents material buildup (especially with adhesives), and extends the time between regrinds.

• Advanced Heat Treatment: Every blade undergoes a vacuum hardening process (typically HRC 60-64 depending on material) to ensure maximum wear resistance without compromising the toughness required for high-speed rotation.

• Custom Engineering for Every Application: From thin foil slitting to heavy-duty paper conversion, we provide custom blade profiles, bevel angles, and spacer sets tailored to your specific machinery and material requirements.
