About Our OEM Tungsten Carbide Crusher Blades

ShengAo OEM Tungsten Carbide Crusher Blades represent the pinnacle of cutting technology for plastic recycling machinery. These hard metal blades are engineered to be the ultimate wear-resistant solution for the most demanding size reduction applications. Manufactured as original equipment manufacturer (OEM) components, they serve as the core cutting elements in granulators, shredders, and crushers used across the recycling industry. Designed to handle abrasive and tough materials that would rapidly degrade conventional steel blades, our carbide blades are engineered for maximum longevity, minimal maintenance, and consistent cutting performance throughout their exceptionally long service life.

Premium Material & Construction

Our crusher blades are manufactured from premium-grade Tungsten Carbide, specifically grades YG6 and YG8, which correspond to international grades K10, K20, and K30. Tungsten carbide is a composite material consisting of tungsten carbide particles (with a fine particle size of -200μm) bonded together with a cobalt binder. This construction gives the blades an exceptional hardness of 89 HRA - far exceeding that of any tool steel. Each blade is precision-ground to achieve superior surface finishes (Ra0.1 to Ra0.3) and exacting dimensional accuracy across a size range from 2 to 500 mm. The material's inherent properties provide extreme wear resistance and anti-corrosion capabilities that ensure consistent cutting performance even in the most abrasive environments.

Key Features & Benefits

Designed specifically for the challenges of modern plastic recycling, these blades deliver unparalleled advantages. The primary benefit is extreme wear resistance, providing a service life that is typically 20-50 times longer than conventional steel blades when processing abrasive materials. This dramatically reduces blade replacement frequency, minimizes machine downtime, and lowers overall operating costs. The anti-corrosion properties ensure consistent performance even in wet or chemically aggressive recycling environments. The exceptional hardness maintains sharp cutting edges for longer periods, ensuring consistent particle size and throughput efficiency. While the initial investment is higher than steel blades, the significantly extended service life delivers a much lower cost per processed ton, making them the most economical choice for high-volume or demanding applications.

Application Industries & Materials

These tungsten carbide blades are specifically engineered for processing the most challenging materials in the recycling industry. They excel at shredding abrasive plastics such as reinforced plastics, fiberglass-filled materials, mineral-filled compounds, and engineering plastics. They are particularly effective for plastic films (especially contaminated films), nylon (PA6, PA66), fiberglass composites, carbon fiber materials, and other reinforced polymers. Key applications include plastic recycling facilities processing post-industrial waste, automotive shredder residue (ASR) processing, electronic waste (e-waste) recycling, and composite material recycling operations. They are ideal for operations where blade wear is a primary cost driver or where consistent particle size is critical to downstream processes.

Frequently Asked Questions (FAQs)

Find answers to common technical questions about our Tungsten Carbide Crusher Blades and their applications in demanding plastic recycling.

When processing abrasive materials (like fiberglass-filled plastics, mineral-filled compounds, or contaminated films), tungsten carbide blades typically last 20 to 50 times longer than premium tool steels like D2 or H13. This lifespan multiplier depends on the specific abrasiveness of the material. For example, when shredding fiberglass-reinforced plastics, carbide blades might last 6-12 months where steel blades would need replacement every 2-3 weeks. While the initial cost is higher, the dramatically reduced downtime and lower cost per processed ton make them the most economical choice for challenging plastic recycling applications.
YG6 and YG8 are Chinese standard designations for tungsten carbide grades, where the number indicates the approximate cobalt binder percentage (6% and 8% respectively). K10, K20, K30 are ISO standard designations. Generally, YG6 corresponds to K10/K20 range and offers a balance between hardness (wear resistance) and toughness. YG8 corresponds to K20/K30 range with slightly higher cobalt content, providing increased toughness (impact resistance) with a minor reduction in hardness. For most plastic recycling applications involving abrasion, YG6/K10-K20 is often optimal. For applications with higher impact (like large lumps), YG8/K20-K30 might be preferred. We can recommend the best carbide grade for shredding based on your material.
Yes, tungsten carbide blades can be resharpened, but the process is more specialized than sharpening steel blades. It requires diamond grinding wheels (as carbide is harder than conventional abrasives) and should be performed by technicians experienced with carbide tooling to avoid thermal cracking. Due to carbide's exceptional wear resistance, resharpening intervals are much longer than with steel blades. Many operations find that the extended service life makes resharpening worthwhile. We can provide guidance on proper resharpening techniques or recommend service providers. It's important to note that improper sharpening can damage the blade, so professional service is recommended for industrial carbide cutting tools.
Tungsten carbide has higher hardness but lower toughness (impact resistance) compared to tool steels. While carbide is more susceptible to chipping or cracking from extreme impact (like hitting large metal pieces), the higher grades we use (YG6/YG8 with appropriate cobalt binder) are engineered for industrial applications. For most plastic recycling where contaminants are small (stones, bits of metal), properly designed carbide blades perform excellently. For operations with frequent large metal contaminants, we might recommend a hybrid approach (carbide for abrasion, with system protections against large tramp metal) or select a tougher carbide grade (YG8/K30). Proper machine operation and feed control are always important for maximizing blade life in recycling.
For our OEM tungsten carbide blades, we offer flexible ordering. The minimum order quantity for customized logos or packaging is just 1 kilogram (and these customizations are free). For standard or custom blade production, we work with various order sizes. The standard lead time is within 25 days for most orders. Specifically, for orders of 1-10 kilograms, the lead time is 25 days. For larger orders (>10 kg), the lead time is negotiable based on production scheduling. We understand the importance of timely delivery for your recycling operation maintenance and strive to meet these targets consistently.
Yes, we operate under a comprehensive ISO9001:2015 certified quality management system. This certification ensures consistent processes, traceability, and continuous improvement in our manufacturing. With each order, we can provide relevant quality documentation including material certificates for the tungsten carbide raw material (verifying grade and composition), dimensional inspection reports, and certification of our ISO9001:2015 compliance. This documentation provides assurance that you are receiving high-quality industrial wear parts manufactured to international standards. For specific compliance needs, please discuss with our technical team.
Yes, we specialize in OEM and custom manufacturing of tungsten carbide blades for virtually any brand and model of granulator, shredder, or crusher, including Vecoplan, Rapid, WEIMA, Zerma, and many others. To ensure perfect compatibility, we need either: 1) The original blade or a detailed drawing with all critical dimensions, 2) The machine make and model along with OEM part number, or 3) Access to the machine for measurement. We replicate the exact dimensions, mounting features, and cutting geometry. Switching from steel to carbide blades might require slight design adjustments to optimize for carbide's properties, which our engineers can advise on. We are experts in hard metal wear part replacement.
While not always required, a proper break-in procedure can help maximize the life of your tungsten carbide blades. We recommend: 1) Initial Inspection: Check blades for any shipping damage and ensure proper installation. 2) Gradual Loading: Start with softer, less abrasive material for the first few hours to allow the cutting edges to "seat" properly. 3) Monitor Performance: Listen for unusual noises and monitor power consumption. 4) Avoid Shock Loading: Feed material consistently, avoiding large lumps that could cause impact. 5) Check Clearances: Ensure proper blade-to-blade or blade-to-counter-knife clearances as specified. Following these steps helps ensure optimal performance from your industrial carbide cutting tools from the start. We provide specific installation and break-in guidance with each order.
