About Our Circular Slitter Blades

The ShengAo Circular Slitter Blade is the core component of rewinding and slitting machinery, engineered for precision cutting in continuous industrial processes. Our newly launched 2024 square blade design offers enhanced stability and cutting performance for high-volume production lines. These custom-made blades are engineered for maximum efficiency and durability in demanding slitting applications.

Premium Material & Construction

Our circular slitter blades are primarily manufactured from SKD-11 High-Speed Steel, a superior Japanese-grade tool steel known for its exceptional wear resistance, high hardness (HRC 58-62), and excellent toughness. We also offer premium alternatives including D2 and DC53 steel for specific application requirements. This material ensures high rigidity and dimensional stability, making the blades ideal for precise slitting of various materials. Each blade features a high-precision, burr-free cutting edge manufactured to exacting standards for smooth operation and consistent performance.

Key Features & Benefits

Designed for extended service life in continuous operation environments, ShengAo blades excel in demanding industrial settings. Their exceptional wear-resistant properties significantly reduce downtime for blade changes and maintenance. The square blade design provides excellent stability and prevents rotation during operation, while the high rigidity prevents deformation under heavy load, ensuring precise and consistent slit width throughout long production runs. The perfect high cutting efficiency translates to increased productivity and superior edge quality on slit materials.

Application Industries & Materials

These versatile circular slitter blades are engineered for a wide range of precision slitting tasks in converting industries. They are highly effective in processing papers, films, foils, laminates, textiles, and flexible packaging materials. Key industries include printing, packaging, label manufacturing, textile processing, and flexible material converting. The blades are compatible with most rewinding machines and slitting equipment, providing reliable performance for creating narrow-width rolls from master reels.

Customization & Quality Assurance

We specialize in providing fully customized blade solutions tailored to your specific machinery and material requirements. From exact dimensions (outer diameter, inner bore, thickness) to specialized edge geometries and material specifications, we manufacture according to your technical drawings. Our commitment to quality is demonstrated through comprehensive video outgoing-inspection and official machinery test reports for material verification. Each blade is securely packed to prevent damage during transit, ensuring it arrives in perfect condition ready for installation and optimal performance.

Frequently Asked Questions (FAQs)

Find quick answers to common questions about our SKD-11 circular slitter blades, customization process, and industrial applications.

SKD-11 (equivalent to D2 steel) is a high-carbon, high-chromium cold work tool steel renowned for its excellent wear resistance, high hardness (achieving HRC 58-62), and good dimensional stability after heat treatment. For circular slitter blades, this translates to a significantly longer service life, reduced downtime for blade changes, and the ability to maintain a sharp cutting edge for precise slitting of materials like films, foils, and papers. It offers a superior balance between toughness and wear resistance compared to many other tool steels.
To place a custom slitter blade order, please provide us with your detailed technical drawings (PDF/DWG format) specifying the outer diameter (OD), inner bore diameter (ID), thickness, keyway details (if any), and preferred material (SKD-11, D2, or DC53). For square blade designs, also specify the square dimensions. You can send your inquiry via our contact form or email. Our engineering team will review the specifications, confirm feasibility, and provide a formal quotation with lead time (typically 35 days for standard custom orders).
Our standard SKD-11 slitter blades are heat-treated to achieve a Rockwell hardness of HRC 58-62. This range is optimal for most slitting applications, providing the perfect balance between edge retention (wear resistance) and necessary toughness to resist micro-chipping. We can adjust the final hardness within this range based on your specific cutting material (e.g., harder for abrasive materials, slightly softer for very tough materials) upon request during the customization process.
Yes, absolutely. We specialize in manufacturing precision replacement blades for a wide range of rewinding and slitting machines from global brands like Kampf, Dusenbery, Goebel, Deacro, Titan, and others. Simply provide the machine model number or the original blade part number/sample. Our team ensures dimensional accuracy and fit, often improving upon the original material (e.g., upgrading to SKD-11 from a lower-grade steel) to enhance performance and lifespan. We are a leading supplier of industrial machine blades.
To guarantee the quality of our high-speed steel blades, we provide comprehensive documentation: 1) Material Test Report/Certificate verifying the chemical composition of the steel. 2) Hardness Test Report confirming the HRC value. 3) Dimensional Inspection Report showing critical measurements. 4) Video Outgoing-Inspection where we share a video of the final product and key checks before shipment. This transparent quality assurance process is part of our commitment to being a reliable industrial blade supplier.
D2 and SKD-11 are very similar (D2 is the American/AISI standard, SKD-11 is the Japanese/JIS standard), both being high-carbon, high-chromium cold work steels with excellent wear resistance. SKD-11 often has tighter controls on impurities. DC53 is an improved version of SKD-11/D2, offering higher toughness (impact resistance) and slightly better machinability, while maintaining good wear resistance. For industrial shredder blades facing high impact, DC53 may be preferable. For pure wear resistance in slitter blades, SKD-11/D2 is excellent. We can advise based on your application.
Yes, we provide attractive bulk order discounts for larger quantities. The discount structure depends on the total order value, material, and complexity. For orders of more than one set or for establishing a long-term supply agreement, please contact our sales team directly for a customized quotation. We also offer more flexible lead time scheduling for volume production of custom industrial blades. Our goal is to build a cost-effective partnership with our clients.
We offer a comprehensive warranty to ensure customer satisfaction: 1) Standard Warranty: 6 months against manufacturing defects in material and workmanship. 2) Warranty on Core Components (Material): 1 year guarantee on the steel material quality. The warranty covers issues like abnormal wear due to material flaws or heat treatment failure. It does not cover damage from improper use, incorrect installation, or cutting unsuitable materials. Our reliable warranty policy underscores our confidence as a trusted blade manufacturer.
