High-Quality Pelletizing rotor knife is designed for pelletizing in the plastics industry Manufacturers, Supplier

The plastic pelletizer blade is designed specifically for plastic pelletizing equipment and the plastics processing industry. Made of high-hardness carbide, it features high hardness, strong wear resistance, and produces neat, sharp pellets. It is widely used in plastic production equipment.

Product Description

Product Description

The plastic pelletizer blade is a key component in pelletizing production. Multiple moving blades are mounted on a cutter drum and work in conjunction with a fixed blade. Their performance directly determines the uniformity and surface quality of the pellets. Our moving blades are made of high-performance carbide, precision CNC machined, and custom-designed with cutting edge angles. This ensures a smooth and stable cutting process, sharpness, and durability. Suitable for pelletizing a variety of plastic materials, including PP, PE, PET, PVC, PA, and PC, the blades are suitable.

Product Features

Selected fracture-resistant alloy grades (YG6X and YG8X) facilitate rework after insert passivation.
CNC machining enables the production of complex insert geometries.
Overall insert straightness is controlled, including flatness and parallelism.
Edge defects are controlled to the micron level.
Available threading tools include solid carbide and welded alloy threading tools.

Frequently Asked Questions

Q How long do your blades last?
In typical PP/PE stranding conditions, the blade life is approximately 1.5–3 times longer than that of ordinary carbide tools due to our high-performance carbide grades.
Q Can the blade geometry be customized?
Yes, we support rapid customization and prototyping. Our process covers everything from design drawing and prototyping to small batch verification and full-scale production with strict tolerance controls.
Q Are your blades compatible with my machine model?
We maintain a comprehensive library of over 300 mainstream domestic and imported models, supporting strand pelletizing, water ring pelletizing, and underwater pelletizing systems.
Q What quality assurance measures are in place?
We utilize a complete production process that ensures full traceability and controllable quality inspection throughout every stage of manufacturing.
Q Which plastic materials are these blades suitable for?
Our blades are highly effective for cutting PP, PE, PET, PVC, PA, PC, PS, ABS, and various other engineering plastics and masterbatches.
Q What manufacturing precision can I expect?
By utilizing CNC machining, we control edge defects to the micron level and ensure strict adherence to flatness and parallelism specifications.
