Rotor Blades

Shengao's high-performance rotary slitter blades are engineered from premium materials for exceptional durability and cutting precision:

• Tungsten Carbide: Superior wear resistance for cutting abrasive materials like fiberglass, carbon fiber, and coated papers, offering up to 50X longer life than standard blades.
• High-Speed Steel (HSS): An excellent all-purpose choice offering fantastic toughness and edge retention for materials like paper, textiles, non-wovens, and certain plastics.
• Premium Tool Steels (e.g., 75Cr1, 80CrV2): Provide high wear resistance and crack resistance for heavy-duty metal processing applications.
• Specialized Coatings (TiN, TiCN, AlTiN, CrN): Reduce friction, prevent material buildup, ensure cooler cuts, and significantly extend time between sharpening.

Each material undergoes specialized heat treatment and precision CNC grinding to achieve optimal hardness (typically HRC 58-64) while maintaining toughness for maximum performance and longevity.

Selecting the optimal circular blade is critical for efficiency and cut quality. Consider these key factors:

1. Material Type & Abrasiveness: Non-abrasive materials (paper, films) may use HSS blades, while highly abrasive materials (composites, sandpaper) require Tungsten Carbide for maximum wear resistance.
2. Material Thickness & Tensile Strength: Thicker, tougher materials often require blades with specific geometries (e.g., single bevel for shearing) and higher hardness.
3. Production Speed & Volume: High-speed, high-volume environments benefit from carbide blades that maintain a sharp edge longer, reducing changeover downtime.
4. Required Cut Quality: Delicate materials like thin films or foils need extremely sharp, polished edges to avoid tearing, while adhesive materials may need non-stick coatings.
5. Slitting Method: Determine if your process uses Razor Slitting (single blade vs. anvil roll) or Shear Slitting (matched male/female blade sets).

Our expert technical team provides free consultations to analyze your specific needs and machine specs, ensuring you get the perfect blade for unparalleled performance and cost-effectiveness.

Proper maintenance is key to extending blade life, ensuring optimal performance, and protecting your investment:

• Regular Cleaning: Remove residue and adhesive buildup after each use to prevent corrosion and maintain cutting precision.
• Periodic Sharpening: Maintain the razor-sharp cutting edge. Professional re-sharpening restores original edge geometry and can significantly extend total blade life.
• Proper Storage: Store blades vertically in a dry, clean environment. Individual protective sleeves or cases are recommended to prevent damage and dulling.
• Rotation in Multi-Blade Systems: Rotate blades periodically to ensure even wear and consistent cut quality across the web.
• Inspection: Regularly check for signs of wear, chipping, or damage before use.

Shengao offers professional blade sharpening and reconditioning services. Detailed maintenance guides are provided with every purchase to maximize your productivity.

Absolutely. As a leading OEM supplier, we specialize in crafting high-precision custom circular blades to your exact specifications:

• Diameter Range: From small precision blades to large industrial diameters up to 2000mm.
• Bore Sizes & Design: Custom bore sizes with keyways, splines, or special drive mechanisms to fit your machinery perfectly.
• Precision Tolerances: Ultra-tight thickness tolerances as low as 0.001mm-0.005mm and concentricity for flawless performance.
• Tooth Configurations & Edge Geometry: Custom tooth count, angle (bevel), geometry (single/double bevel, round edge), and polished finishes for specific materials.
• Special Coatings & Materials: TiN, TiCN, AlTiN, CrN coatings, and custom material blends for unique challenges like extreme heat or corrosion.

Our engineering team can develop and deliver prototype blades within 7-10 working days. We support low Minimum Order Quantities (MOQ), starting from just 5 units for custom solutions, making bespoke blades accessible.
