Recommended #3: Shengao SKD-11 Rotor and Bed Granulator Knives
1. Superior Sharpness Retention:
Made from SKD-11 (D2 equivalent) cold work steel, these blades maintain a razor-sharp edge through extended runs. This results in clean, uniform granules and significantly lower power consumption compared to standard blades, as the machine doesn't have to work as hard.
2. Optimized Geometry for Clean Shearing:
The precise shear and clearance angles are calculated for efficient scissor-action cutting. This clean shear action minimizes friction and heat generation, effectively reducing the risk of plastic melting and sticking to the blades—a common headache in granulation.
3. Perfectly Matched Sets for Smooth Operation:
We supply perfectly matched rotor and bed blade sets. Each set is ground together to ensure flawless alignment and consistent cutting clearance, which is critical for achieving high-quality regrind and protecting your granulator from premature wear.

4. Professional Serrated Cutting Blades
Brand Popularity: ★★★★☆
Brand Introduction: Shengao's serrated blades feature "Anti-Slip Tooth Geometry," a 2025 innovation for slippery materials.
Market Position: Essential for packaging and textile industries.
Why It's Listed: Provides a positive grip on materials, preventing slippage for perfectly straight cuts.
Recommended #4: Shengao High-Speed Steel Serrated Slitter Blades
1. Non-Slip, Precision Cutting:
The laser-cut, precision-ground teeth grab onto slippery materials like laminated films, non-wovens, and rubber, preventing movement during the cut. This guarantees perfectly straight, accurate slitting without frayed edges or misalignment.
2. Extended Sharpness with Multi-Point Contact:
Unlike plain blades, the serrated edge distributes wear across multiple points. This means the blade remains effective for much longer, even if individual micro-teeth wear, providing a more consistent cut life and reducing blade replacement costs.
3. Versatile for a Range of Materials:
Available in different tooth pitches and patterns (fine, medium, hook), these blades can be customized for various materials. From cleanly cutting sticky adhesive tapes to tearing through fibrous materials, there's a serrated solution for your specific challenge.
