Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo SKD-11 High-Performance Double Shaft Shredder Blades with CNC precision and 3-year warranty.

SKD-11 (equivalent to D2 tool steel) is superior for double shaft shredder blades due to its exceptional combination of properties critical for industrial recycling: 1) Extremely High Wear Resistance: Contains high chromium and carbon content, forming hard carbides that resist abrasion from plastics, rubber, and contaminants. 2) Good Toughness: Can withstand the impact and shock loads of shredding dense, heterogeneous materials. 3) High Hardness Retention: Maintains its hardness (typically HRC 58-62) even under the frictional heat generated during continuous operation. 4) Dimensional Stability: Responds well to heat treatment with minimal distortion, which is crucial for maintaining the tight tolerances (±0.002 mm) required for precise blade alignment in dual-shaft systems.
CNC precision with ±0.002 mm tolerance in blade thickness is critical for optimal double shaft shredder performance. This ultra-tight tolerance ensures: 1) Perfect Blade Alignment: All blades on the rotor have identical thickness, creating a uniform cutting clearance between the rotor and counter blades. This eliminates uneven wear and inefficient cutting. 2) Reduced Vibration and Noise: Precise dimensional consistency minimizes dynamic imbalance, leading to smoother, quieter operation and less stress on bearings. 3) Extended Blade Life: Even wear across all cutting edges maximizes the service life of the entire blade set. 4) Consistent Output Size: Uniform cutting geometry produces more consistent particle size in the shredded material. This precision directly translates to higher efficiency, lower maintenance, and better product quality in industrial recycling.
Yes, a 3-year warranty for shredder blades is considered industry-leading, as most manufacturers offer 1 year or less. Our warranty covers defects in material and workmanship under normal operating conditions. This includes premature cracking, breaking, or abnormal wear that is not attributable to improper installation, operation outside design limits (e.g., shredding materials much harder than specified), lack of maintenance, or accidental damage. To make a claim, provide the order number and evidence (photos/video) of the defect. This extended warranty reflects our absolute confidence in the quality of our SKD-11 blades, their CNC precision manufacturing, and heat treatment processes, offering unparalleled peace of mind for your investment in industrial recycling equipment.
W6Mo5Cr4V2 (M2) and W18Cr4V (T1) are high-speed steels (HSS) with different properties than SKD-11 (D2). Choose HSS grades when: 1) High Heat Resistance (Red-Hardness) is Critical: HSS retains its hardness at much higher temperatures (500-600°C+) than D2. This is vital in high-speed shredding or when processing materials that generate significant heat through friction. 2) Combined Wear and Toughness Needed: M2 HSS offers a good balance. 3) Superior Abrasion Resistance at High Speed: For extremely abrasive streams at high RPMs. SKD-11/D2 remains the best all-around choice for most dual-shaft shredding due to its excellent wear resistance and good toughness at lower cost. For specific high-heat or high-speed scenarios, our engineers can recommend the optimal HSS grade.
Sharpness in the range of 18N to 30N refers to the cutting force required, often measured with a precision cutting force tester (like a CATRA or similar). A lower value (e.g., 18N) indicates a sharper edge that cuts with less force. Our specified range means the blades are finished to a precise sharpness that balances two key factors: 1) Cutting Efficiency: A sharp enough edge (closer to 18N) requires less motor power to shear material, improving energy efficiency and reducing heat generation. 2) Edge Durability: An extremely sharp edge can be more fragile. The range ensures the edge is robust enough (closer to 30N for tougher applications) to resist micro-chipping during the initial engagement with hard materials. Our numerical control grinding achieves this optimal balance for your specific plastic crusher machine application.
The 35-day lead time for a single piece is our standard for a fully customized, precision-made blade. This period encompasses several critical stages: 1) Engineering Review & Programming: Creating CNC programs for a one-off custom part. 2) Material Procurement: Sourcing the specific steel grade (SKD-11, etc.) if not in stock. 3) Precision Machining: CNC milling, turning, and drilling to exacting tolerances. 4) Heat Treatment: Controlled hardening and tempering cycles. 5) Precision Grinding: Achieving the final dimensions and sharpness with CNC grinding. 6) Quality Inspection & Reporting. For bulk orders (>1 piece), economies of scale apply, and lead time is negotiable. Expedited production may be possible for urgent needs—please contact us directly to discuss expedited options and associated costs.
Yes, we offer logo and graphic design customization on our blades, subject to a minimum order quantity of 2 pieces. This is typically achieved through laser engraving or etching onto a non-critical surface of the blade (e.g., the side or mounting hub). This service allows for brand identification, part numbering, or other markings. To proceed, please provide a high-resolution vector file (e.g., AI, EPS, DXF) of your logo/design. Our engineering team will review it to ensure it does not compromise the blade's structural integrity or interfere with its function. This added customization is a unique value-add for companies looking to brand their industrial spare parts or ensure traceability.
Our video outgoing-inspection and machinery test report provide complementary, multi-layered proof of quality. The Machinery Test Report is the formal, documented evidence. It includes quantifiable data: material certification, hardness test results (HRC), dimensional inspection records against your drawing (verifying the ±0.002 mm tolerance), and visual inspection conclusions. The Video Outgoing-Inspection is the visual, real-time companion to the report. It shows the actual blades being measured, the testing equipment in use, the surface finish, and the final packaging. The video proves the report's data corresponds to the physical product you will receive. Together, they offer complete transparency and build trust before your high-precision industrial blades ship, ensuring they meet every specification.
