Main Features
Precision Adjustment: The elongated slots are crucial for adjustable positioning shear blades, allowing for precise clearance setting between fixed and rotary knives, which is vital for granulation quality.
Premium Tool Steel: We offer standard options like D2 for wear resistance (D2 steel moving cutter for plastic) and HSS (HSS slitter and cutter blades) for high-speed impact applications.
High Tolerance Machining: Manufacturing is focused on achieving extremely tight tolerances in thickness and parallelism, reducing vibration and ensuring a consistent cut.
Versatile Use: Ideal for use as plastic recycling machine fixed blades (stator knives) or moving (rotor) knives in granulators.
Custom Dimensions: We specialize in non-standard sizes, including custom thickness rectangular machine knives, to meet specific machine requirements.
Advantages
Optimized Granule Size: The precise gap setting enabled by the slots and high-precision finish results in uniform granule size and minimal fines.
Extended Service Life: Exceptional material quality ensures they are long-life film trimming knife replacement options, reducing consumable costs.
Reduced Downtime: Quick and accurate installation due to precision slot and dimension machining.
Strong Edge Integrity: Designed to withstand the shearing of hard and thick plastic scrap without chipping or premature dulling.
Product Specifications
Granulator Knives: Both moving and fixed/bed knives for various plastic recycling machines.
Trimming Blades: Used for cutting and trimming edges on wide-web processing lines.
Material Options: Tailored based on the plastic type (e.g., tough engineering plastics require D2, soft films may use high-chrome steel).
Compatibility: Suitable for major granulator brands.
Customization: We work from customer samples or blueprints for complex custom thickness rectangular machine knives and slot patterns.
