Circular Slitter Blades

Shengao Precision Circular Slitter Blades are crafted from premium materials to ensure exceptional durability and cutting performance:

• Tungsten Carbide: Superior wear resistance (HRA 90-92.5) for cutting abrasive materials and extended lifespan
• High-Speed Steel (HSS): Excellent sharpness retention and heat resistance for high-volume paper and film cutting applications
• Alloy Steel: D2, 9CrSi, and Cr12MoV grades for long-lasting sharpness and durability in various cutting environments
• Specialty Coatings: TiN, TiCN coatings for reduced friction, non-stick properties, and enhanced corrosion resistance

Each material undergoes specialized heat treatment and cryogenic processing to achieve optimal hardness (HRC 58-64 / HRA 90-92.5) while maintaining toughness for precision cutting operations.

Selecting the appropriate circular slitter blade depends on several key factors:

1. Material Type: Different materials (paper, film, metals, textiles) require specific blade compositions and edge geometries
2. Material Thickness: Thicker materials require blades with appropriate hardness and edge geometry
3. Production Speed: High-speed applications need blades with specialized steel grades and heat treatment
4. Cut Quality Requirements: Fine-cut applications require blades with precision grinding and optimal edge angles (typically 15°-30°)
5. Machine Compatibility: Ensure proper fit for Polar, Wohlenberg, and other slitting systems

Our technical team provides customized recommendations based on your specific requirements and machine specifications.

Proper maintenance extends blade life and ensures optimal cutting performance:

• Regular Cleaning: Remove paper dust, film residue, and debris after each use to prevent buildup and maintain cutting precision
• Periodic Sharpening: Maintain cutting edge sharpness using appropriate grinding equipment and techniques
• Proper Storage: Store blades vertically in dry, temperature-controlled environments with protective coatings
• Rotation Practice: Rotate blades in multi-blade systems to ensure even wear and consistent performance
• Lubrication: Apply appropriate lubricants to reduce friction and prevent rust during storage

Shengao offers professional sharpening services and provides detailed maintenance guides with every purchase.
