About Our Pelletizer Knife (ST-017) & Crusher Blades
The pelletizer knife (model ST-017) is a precision cutting blade designed for plastic recycling and size reduction machinery. As a critical component of granulators, crushers, and pelletizing systems, these knives work in tandem with rotor blades to efficiently process plastic scrap, rubber products, and recyclable materials. Our standard L129xW35mm x T5mm knives are engineered to deliver consistent cuts, producing uniform pellets or flakes ideal for downstream recycling processes, material recovery, or direct reuse.
Premium Material & Construction
Our pelletizer knives are manufactured from high-precision tool steels including D2, SKD11, M2, ASP, and High-Speed Steel (HSS). These materials are selected for their superior edge retention, wear resistance, and toughness. Each blade undergoes specialized heat treatment to achieve an optimal hardness of 56-63 HRC, providing the perfect balance between sharpness and durability for cutting various plastics and rubber. The blades feature a polished surface finish and precise roundness geometry, ensuring smooth operation, minimal friction, and consistent cutting performance in high-speed granulation.
Key Features & Operational Benefits
Designed for longevity in demanding recycling environments, our pelletizer knives offer significant operational advantages. The primary key benefits are extended wear life and precision cutting. The high hardness (HRC 56-63) ensures excellent resistance to abrasion from reinforced plastics and rubber compounds. The polished surface reduces material buildup and drag, while the precise geometry ensures clean, uniform cuts. This translates directly into reduced downtime for blade changes, consistent pellet/flake quality, and higher overall equipment efficiency (OEE), maximizing your plastic recycling operation's productivity.
Application Industries & Materials
These versatile knives are specifically engineered for the plastic recycling industry and related size-reduction applications. They excel in processing post-consumer plastics (PET, HDPE, PP, PVC), plastic film, rigid plastic containers, engineering plastics, and rubber products. Industries that heavily rely on these precision knives include plastic recycling facilities, plastic pelletizing plants, synthetic fiber production, rubber reclaiming operations, and waste management companies. Whether installed in a central granulator for bulk reduction or a precision pelletizer for uniform flake production, our ST-017 knives deliver reliable performance essential for efficient material recovery and reprocessing.
Customization & Comprehensive Quality Assurance
We specialize in providing fully customized OEM and ODM blade solutions. While we offer the standard ST-017 model, all specifications—including dimensions, edge geometry, material grade, and hardness—can be tailored to fit your specific granulator or crusher model. Our manufacturing processes are certified to ISO9001:2008 standards, ensuring consistent quality. We can provide detailed material certifications and performance data upon request. Our commitment to precision and durability means you receive a high-performance cutting tool engineered for your specific plastic or rubber processing application, backed by our expertise in tool steel manufacturing.
