Main Features
Optimized for Impact: Manufactured using through-hardened steel to withstand the high impact forces inherent in heavy-duty shredding and granulation.
Superior Edge Retention: Materials like D2 and HSS ensure a long-lasting, sharp point, crucial for effective material feeding and cutting.
Precise Geometry: The customized V-cut granulator blades shape is precision-ground, ensuring a perfect clearance angle when paired with rotary knives for optimal shearing action.
Easy Replacement: Standardized hole patterns make these HSS shredder replacement blades easily interchangeable with OEM parts.
Versatility in Recycling: Excellent performance when used as recycled plastic chopping knives for PET, PVC, HDPE, and engineering plastics.
Advantages
High Impact Resistance: Our blades are treated to resist chipping and breaking, leading to fewer unplanned stops and reduced damage to the cutter head.
Increased Throughput: The sharp point and high-impact plastic recycling blades material efficiently process dense materials, leading to higher output rates.
Customization Experts: We specialize in unique, non-standard pointed corner cutting insert designs tailored to improve the efficiency of older or specialized machinery.
Reduced Noise & Vibration: The precise clearance achieved by our high-tolerance manufacturing reduces friction and operational noise.
Product Specifications
