Main Features
- Superior Wear Resistant Steel Matrix: Premium Cr12MoV and D2 tool steels with optimized vacuum hardening deliver outstanding abrasion resistance, standing up to continuous friction from plastic strands and filler additives.
- Adjustable Slotted Mounting Holes: Elongated hole design enables fine adjustment of cutting gap and blade position, simplifying installation and adapting to different pelletizer tool holder configurations.
- Uniform Precision Ground Edges: Full-length CNC grinding ensures consistent edge sharpness and straightness, producing evenly sized pellets without uneven length or chipping.
- Impact-Resistant Reinforced Body: Thickened blade structure absorbs repeated impact from extruded strands, preventing edge chipping and blade deformation under heavy continuous operation.
- Stress-Relieved Stable Structure: Deep cryogenic treatment eliminates internal residual stress, preventing dimensional shift and maintaining long-term cutting accuracy after extended use.
Advantages
- Consistent Uniform Pellet Quality: Precision sharp edges produce regularly sized, smooth-surface pellets, reducing out-of-spec products and improving finished material marketability.
- Reduced Dust & Material Waste: Clean shear cutting minimizes fine plastic powder and scrap, lowering raw material loss and reducing equipment cleaning frequency.
- Extended Production Uptime: High wear resistance and durable construction extend sharpening and replacement intervals, cutting machine downtime and improving overall line output.
- Fast Setup & Adjustment: Slotted mounting holes simplify blade replacement and gap calibration, shortening changeover time and improving production flexibility.
- Cost-Effective OEM Alternative: Factory-direct pricing delivers OEM-level durability and precision at significantly lower procurement costs for plastic processing facilities.
