About Our OEM Granulator & Shredder Blades
Our precision-engineered OEM replacement blades and knives are the core cutting components for leading European and North American recycling machinery brands. Designed as direct replacements for Herbold, Zerma, Weima, and Cumberland shredders and granulators, these blades are engineered to restore your equipment to its original cutting performance. We offer both standard sizes (like 385mm, 486mm, 585mm lengths) and fully customized dimensions to ensure perfect compatibility with your specific machine model and application requirements.
Premium Material & Precision Engineering
We manufacture our granulator knives from high-performance alloy tool steels including D2, SKD11, 1.2379, M2, ASP, and various HSS grades. Each material is selected for specific applications: D2 and SKD11 for excellent wear resistance in plastic recycling, and high-speed steels for high-temperature operations. Our blades undergo specialized heat treatment to achieve an optimal hardness range of HRC 56-63, providing the perfect balance between edge retention and toughness. Every blade is precision-machined to achieve high-accuracy dimensions and burr-free edges, ensuring smooth operation and consistent particle size output in demanding recycling environments.
Key Features & Operational Benefits
Designed for maximum performance and longevity, our replacement blades deliver significant operational advantages. The high hardness (HRC 56-63) ensures extended service life between sharpening cycles, reducing maintenance frequency and associated downtime. Our precision manufacturing process guarantees perfect fit and alignment in your original equipment, preventing vibration and uneven wear. The blades' excellent wear resistance handles abrasive materials like filled plastics and copper wire, while their impact-resistant design withstands occasional hard contaminants. These features combine to deliver higher throughput, consistent particle size, and reduced operating costs for your plastic, wood, or copper wire recycling operation.
Application Industries & Material Processing
These versatile blades are engineered for a wide range of size reduction applications across multiple recycling sectors. They are highly effective in processing various plastics (including engineering plastics, films, and lumps), wood waste, copper wire, and other recyclable materials. Specifically designed as OEM replacements for major brands, they are ideal for plastic recycling facilities, wood processing plants, electronic waste (WEEE) recycling operations, cable and wire recovery systems, and general industrial scrap processing. Whether installed in a granulator for fine cutting or a shredder for coarse reduction, our blades provide reliable performance that matches or exceeds original equipment specifications.
Customization & Comprehensive Quality Assurance
We specialize in providing fully customized OEM replacement solutions for virtually any granulator or shredder model. From exact dimensional matching to material specification and hardness requirements, we can tailor blades to your specific machine and material stream. Our commitment to quality is demonstrated through ISO9001:2008 and TUV certified manufacturing processes and comprehensive documentation including official machinery test reports and video outgoing-inspection for every order. Backed by a solid 6-month warranty and a minimum order quantity of just 10 pieces, our blades represent a cost-effective, high-performance solution. Securely packaged in wooden boxes or custom packaging, they arrive ready for installation and immediate productivity in your recycling operation.
