Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Double Shaft Shredder Blades for industrial plastic crushing applications.

The ±0.002 thickness tolerance represents exceptional precision in manufacturing double shaft shredder blades. This tight tolerance ensures: 1) Perfect Blade Alignment: Consistent thickness across all blades allows for uniform cutting action and balanced load distribution. 2) Reduced Vibration: Minimizes operational vibration that can cause premature wear and machine damage. 3) Consistent Cutting Performance: Ensures each blade in the system cuts with equal efficiency and force. 4) Extended Bearing Life: Reduces uneven stresses on shredder shafts and bearings. 5) Energy Efficiency: Optimized cutting reduces power consumption. This level of precision is critical for high-volume plastic recycling operations where consistent particle size and minimal downtime are essential for profitability.
Choose D2 tool steel when processing highly abrasive plastic materials like glass-filled plastics, mineral-filled compounds, or heavily contaminated plastic streams where maximum wear resistance is critical. D2 offers excellent edge retention and abrasion resistance. Choose SKD11 for a balance of wear resistance and toughness, ideal for general-purpose plastic recycling with occasional hard contaminants. Choose Cr12Mov when improved toughness and shock resistance are needed for processing bulky or irregular plastic pieces that may cause impact loading. Our engineers can recommend the optimal material based on your specific plastic waste composition, throughput requirements, and maintenance schedule for double shaft shredder applications.
Our exceptional 1.5-year warranty provides comprehensive coverage for double shaft shredder blades: 1) Material Defects: Coverage for flaws in D2, SKD11, or Cr12Mov steel composition. 2) Manufacturing Workmanship: Protection against manufacturing flaws affecting installation or performance. 3) Premature Wear: Coverage for abnormal wear not caused by improper operation or foreign objects. 4) Hardness Failure: Protection if blades fail to maintain specified HRC 56-58 hardness under normal use. 5) Structural Failure: Coverage for cracking or breaking not caused by impact with metals or improper installation. The warranty period begins from delivery date and reflects our confidence in manufacturing quality for industrial plastic recycling equipment components.
Numerical control (CNC) grinding provides significant advantages over conventional grinding methods for double shaft shredder blades: 1) Exceptional Precision: Achieves consistent ±0.002 thickness tolerance and +50 micron accuracy. 2) Consistent Edge Geometry: Maintains identical cutting angles across all blades in a set. 3) Repeatability: Ensures identical blade profiles for replacement sets. 4) Burr-Free Edges: Produces clean cutting edges with 18N-30N sharpness without micro-burrs. 5) Reduced Heat-Affected Zone: Minimizes thermal distortion during grinding. 6) Extended Service Life: Precise geometry distributes wear evenly across cutting edges. This advanced manufacturing technique is essential for high-performance plastic recycling operations requiring consistent particle size and minimal downtime.
Starting from 100 pieces minimum order, we offer comprehensive customization: Logo/Graphic Design (laser etching or engraving of your company logo, part numbers, or identification codes directly on blade surfaces), Custom Packaging (branded boxes, specialized protective packaging, or customized labeling systems), and Full Size Customization (tailored dimensions to match specific double shaft shredder models). For logo/graphic customization, we work with your provided artwork to ensure professional results that enhance brand recognition. Customization fees are calculated based on complexity and quantity, with prices confirmed upon request. These options enable medium to large plastic recycling operations to obtain branded, precisely fitted blades for their specific equipment requirements.
The 18N-30N sharpness rating represents an optimal range for double shaft shredder blade performance in plastic cutting applications: 1) Efficient Cutting ActionReduced Energy Consumption: Sharper blades require less power to achieve the same cutting results. 3) Consistent Particle Size: Maintains uniform cutting action for predictable output size distribution. 4) Reduced Heat Generation: Efficient cutting minimizes frictional heat that can degrade plastic materials. 5) Extended Sharpness Retention: The specified range balances initial sharpness with durability for longer service intervals. This optimized sharpness is particularly important for high-volume plastic recycling operations where energy efficiency and consistent output quality directly impact operational costs.
Our double shaft shredder blades incorporate multiple safety features: 1) Precision Balance: Each blade is balanced to minimize vibration that can lead to component fatigue and failure. 2) Secure Mounting Design: Engineered for positive retention in shredder housings. 3) Burr-Free Edges: All edges are deburred to prevent accidental cuts during handling and installation. 4) Material Integrity: Premium steel grades with proper heat treatment reduce risk of catastrophic failure. 5) Consistent Performance: Predictable cutting behavior reduces risk of material jam-ups and associated hazards. 6) Clear Identification: When customized, blades can include safety warnings or handling instructions. These features contribute to the high safety level rating, essential for protecting operators and equipment in industrial plastic recycling facilities.
Our custom-sized double shaft blades offer several advantages compared to OEM parts: 1) Material Options: We offer multiple steel grades (D2, SKD11, Cr12Mov) versus OEM's typically single option. 2) Enhanced Precision: Our ±0.002 tolerance and +50 micron accuracy often exceed OEM specifications. 3) Longer Warranty: 1.5-year warranty compared to typical 6-12 month OEM warranties. 4) Customization Flexibility: Branding and packaging options not typically available from OEMs. 5) Cost EffectivenessRapid Availability: 35-day lead time versus potentially longer OEM delivery. For compatibility, provide your machine model or blade samples, and we'll manufacture precision replacement blades that match or exceed OEM performance for your plastic crusher machine.
