1. Table of Contents
Introduction
Shengao Tungsten Carbide Shredder Blades represent the pinnacle of cutting technology for demanding recycling applications. Engineered with premium-grade tungsten carbide, these blades deliver 8-10X longer service life than standard steel blades while maintaining superior cutting performance in metal shredding, plastic recycling, and e-waste processing operations. With global waste generation exceeding 2.01 billion tons annually and recycling rates still below 20% for many materials, efficient size reduction technology has never been more critical. Shengao blades withstand extreme abrasion from ferrous metals, impact resistance from electronic components, and chemical corrosion from plastic additives, making them the optimal solution for operations seeking to maximize uptime and reduce operational costs.
2. Shengao Blades: Features & Functions
Shengao's engineering focuses on solving the core challenges in industrial shredding: rapid blade wear, frequent replacements, and inconsistent performance across varied materials. Our tungsten carbide blades are designed to withstand the most abrasive recycling applications while maintaining cutting precision.
2.1. Tungsten Carbide Superiority
Shengao blades utilize premium tungsten carbide with cobalt binders (Grade YG15) featuring hardness ratings of 89-92 HRA. This composition delivers exceptional wear resistance that outperforms conventional tool steel by 8-10 times in abrasive applications. The microstructure features uniform carbide grain distribution (1-3μm) that prevents microfractures while maintaining impact resistance. Unlike standard blades that rapidly dull when processing reinforced plastics or metal-contaminated streams, Shengao blades maintain sharp cutting edges through extended operational cycles, reducing changeover frequency by up to 70%.
2.2. Precision Engineering & Geometry
Each blade undergoes CNC grinding with tolerances within ±0.002mm, ensuring perfect balance and consistent cutting performance across multi-blade rotor systems. The optimized tooth geometry features alternating shear and impact profiles that create efficient material fracture points while minimizing energy consumption. For metal shredding applications, our specialized hook-tooth design generates maximum torque at initial engagement, while plastic-specific blades feature wave patterns that prevent material wrapping. This precision engineering reduces vibration-related wear on shredder shafts and bearings, extending overall machine lifespan.
2.3. Material Versatility
Shengao blades are engineered for cross-application performance in mixed-material recycling streams. The tungsten carbide composition maintains cutting integrity when transitioning between:
- Ferrous Metals: Handles steel, iron, and automotive scrap
- Non-Ferrous: Efficiently processes aluminum, copper, and brass
- Plastics: Maintains sharp edges through reinforced polymers and glass-filled compounds
- E-Waste: Withstands impact from circuit boards and electronic components

5. Industry Applications
Shengao blades deliver superior performance across critical recycling sectors.
5.1. Metal Recycling
In metal shredding operations, Shengao blades withstand extreme abrasion from ferrous materials while maintaining cutting efficiency for non-ferrous separation. The tungsten carbide construction resists impact damage from heavy scrap loads and maintains dimensional stability at high operating temperatures. With global steel recycling reaching 630 million tons annually, efficient shredding blades directly impact operational profitability.
5.2. Plastic Recycling
For plastic recyclers, Shengao blades maintain sharp cutting edges through glass-filled polymers and reinforced compounds that rapidly degrade conventional blades. The specialized geometry prevents melting and buildup when processing challenging materials like PVC or nylon. With plastic recycling rates below 10% globally, efficient size reduction technology is essential for improving recycling economics.
5.3. E-Waste Recycling
In e-waste processing, Shengao blades withstand impact from circuit boards and connectors while resisting corrosion from brominated flame retardants. The precision cutting action enables clean component liberation without excessive fines generation. With global e-waste exceeding 53 million tons annually, specialized shredding technology is critical for efficient material recovery.

8. Frequently Asked Questions (FAQ)
What makes tungsten carbide superior to tool steel for shredder blades?
Tungsten carbide maintains hardness at elevated temperatures, resists abrasive wear 8-10 times better than tool steel, and maintains cutting edge integrity through impact loading. This translates to significantly longer service life in demanding recycling applications.
Can Shengao blades handle mixed material streams?
Yes, our tungsten carbide blades are specifically engineered for challenging mixed streams like e-waste (circuit boards + plastics + metals) and contaminated plastic recycling. The material composition resists both abrasive and impact damage from incidental metal in plastic streams.
How do I determine the optimal blade geometry for my application?
Provide our engineering team with details of your processed materials, machine specifications, and desired output size. We'll recommend the optimal tooth configuration, cutting angle, and carbide grade for your specific operation.
What is the typical ROI when switching to tungsten carbide blades?
Most operations achieve full ROI within 4-6 months through reduced changeover downtime, decreased replacement costs, and improved throughput. Operations processing abrasive materials often see ROI in as little as 60 operational days.
How should I store spare blades?
Store blades in climate-controlled environments with protective coating intact. Use blade trees or individual protective sleeves to prevent edge damage. Maintain humidity below 60% to prevent corrosion of steel substrates.
