Rotary Slitter Blades

Shengao rotary slitter blades are crafted from premium materials to ensure exceptional durability and cutting performance in demanding industrial applications:

• Tungsten Carbide: Superior wear resistance and hardness (HRC 58-65) for cutting abrasive materials including metals, composites, and technical fabrics
• High-Speed Steel (HSS): Excellent heat resistance and durability for high-volume production environments and continuous operation
• Tool Steel Alloys (D2, SKD-11): High-carbon steel with chromium content providing optimal toughness and edge retention for various cutting applications
• Coated Variants: Specialized coatings including TiN, TiCN, TiAlN, and DLC for reduced friction, heat resistance, and extended blade lifespan

Each material undergoes specialized heat treatment and precision engineering to achieve optimal hardness (HRC 45-65) while maintaining toughness and structural integrity for industrial slitting operations.

Selecting the appropriate rotary slitter blade depends on several key factors specific to your operational requirements:

1. Material Type: Different materials (metals, plastics, paper, textiles) require specific blade compositions and edge geometries for optimal cutting performance
2. Production Requirements: High-speed applications need blades with optimized tooth geometry and advanced coatings for heat resistance and durability
3. Precision Needs: Fine-cut applications require blades with higher tooth counts and precision grinding (tolerances ±0.01-0.05mm) for clean, accurate cuts
4. Thickness Capacity: Thicker materials require blades with larger diameters and specialized configurations to handle increased cutting forces
5. Environmental Conditions: Consider humidity, temperature, and corrosion factors when selecting blade materials and coatings

Our technical team provides customized recommendations based on your specific material characteristics, production volume, and performance expectations for optimal results.

Proper maintenance extends blade life and ensures optimal cutting performance for rotary slitter blades:

• Regular Cleaning: Remove resin, pitch, and debris after each use using appropriate cleaning solutions to prevent buildup and maintain cutting efficiency
• Professional Sharpening: Maintain cutting edge sharpness through professional sharpening services using diamond wheels for carbide blades or appropriate abrasives for steel blades
• Proper Storage: Store blades in dry, controlled environments (15-25°C, humidity below 50%) using protective covers to prevent damage and corrosion
• Performance Monitoring: Track cutting efficiency and inspect for wear patterns, chipping, or damage regularly to determine optimal maintenance intervals
• Rotation System: Rotate blades in multi-blade systems to ensure even wear and extended service life across all blades

Shengao offers professional sharpening services and provides detailed maintenance guidelines specifically designed for rotary slitter blades to maximize their lifespan and performance.
