Slitter Blade for Industrial Paper, Film & Metal Cutting – Precision CNC-Machined Circular Blades with Polished Finish Experience unmatched performance and durability with our custom industrial slitter blades, engineered for precision cutting in paper mills, plastic film production, metal sheet processing, and pharmaceutical equipment. Designed by Shenzhen Wanda Xiang Industrial Co., Ltd., a leading manufacturer with over 13 years of expertise, these circular knives deliver consistent results across high-speed industrial applications—ensuring clean cuts without burrs, scratches, or discoloration. Key Features: - Customizable dimensions and materials including 9CrSi, Cr12MoV, SKD-11, SKH-51, and tungsten carbide - Surface finish: polished for reduced friction and enhanced wear resistance - Hardness range: HRC 44–68 for optimal balance between toughness and edge retention - Manufactured via CNC milling for micron-level accuracy and repeatability - Available in multiple sizes (e.g., Ф105*Ф70*1.2mm) tailored to specific machine requirements - OEM/ODM services supported for unique configurations and specialized needs Detailed Description: These industrial slitting tools are crafted from high-strength alloy steels and advanced tool materials, heat-treated to maximize hardness while maintaining structural integrity under continuous operation. The precision honing process ensures minimal cutting resistance, allowing smooth passage through delicate materials like gold leaf, aluminum foil, and thin films. Each blade undergoes rigorous quality control to meet ISO 9001:2008 standards, guaranteeing reliability in demanding environments such as printing presses, converting lines, and cold rolling mills. Whether you require a standard circular knife for paper roll slitting or a custom-designed insert blade for automated machinery, our team can produce exactly what your production line demands. Ideal Applications: Perfect for use in paper converting machines, plastic film slitters, packaging equipment, metal shearing systems, and pharmaceutical blister packers. These blades maintain sharpness over extended periods, reducing downtime and improving overall efficiency. They are especially effective when handling sensitive substrates where surface quality is critical—such as glossy paper, laminated films, and medical-grade foils. Customer Feedback: Users consistently praise the long service life and consistent cut quality. Many report fewer rejects due to edge imperfections, which translates into cost savings and improved product consistency. One client noted, “After switching to these blades, we saw a 30% reduction in blade replacements per month—without compromising on cut quality.” Frequently Asked Questions: What type of manufacturing facility produces these blades?
