Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Industrial Plastic Crusher Blades & Rubber Recycling Knives for plastic and rubber processing applications.

9Cr Si offers excellent toughness and good wear resistance, making it suitable for general plastic crushing applications. SKD-11 provides superior dimensional stability and wear resistance, ideal for precision cutting of engineering plastics. D2 delivers exceptional wear resistance and is perfect for processing abrasive materials like filled plastics or rubber with contaminants. DC53 combines high toughness with good wear resistance, making it excellent for applications with impact risks or mixed material streams. For general-purpose plastic and rubber recycling, DC53 often provides the best balance. However, the optimal choice depends on your specific material characteristics and operating conditions in industrial size reduction applications.
You can provide specifications for custom plastic crusher blades in several ways: 1) Technical Drawing - Send a PDF, DWG, or DXF file with all dimensions, tolerances, hole patterns, and material specifications. 2) Physical Sample - Mail us an existing blade for precise reverse engineering. 3) Machine Information - Provide the make, model, and serial number of your crusher or granulator. 4) Detailed Measurements - Supply key dimensions including length, width, thickness, hole diameters, and center distances. Our engineering team will review your specifications, create a detailed drawing for your approval, and then proceed with manufacturing. This ensures perfect compatibility with your industrial plastic processing equipment.
Yes, our plastic crusher blades and rubber recycling knives are designed to handle both material types effectively when made from appropriate materials like D2 or DC53. However, optimal performance requires consideration of: 1) Material ratio - Blades can handle mixed streams but perform best when optimized for the primary material. 2) Edge geometry - Rubber may benefit from slightly different edge angles than plastic. 3) Hardness selection - Rubber processing often benefits from slightly lower hardness for better toughness. For dedicated rubber recycling operations, we may recommend specific edge treatments or geometries. If you process both materials regularly, we can design blades that provide the best compromise for your specific industrial recycling application.
To maximize the lifespan of plastic crusher blades: 1) Regular inspection for wear, chips, or cracks. 2) Proper installation with correct torque on all fasteners. 3) Timely sharpening when cutting efficiency decreases (before excessive wear). 4) Cleaning to remove material buildup that can cause imbalance. 5) Proper storage when not in use (clean, dry, protected from corrosion). 6) Avoid overheating by not overloading the machine. 7) Use appropriate blade material for your specific plastic/rubber type. 8) Regular machine maintenance to ensure proper alignment and operation. Following these procedures can extend blade life by 30-50% in industrial recycling operations.
Our machinery test report includes: 1) Material certification verifying steel grade. 2) Hardness testing results (HRC values at multiple points). 3) Dimensional inspection report with actual measurements vs. specifications. 4) Visual inspection findings. 5) Heat treatment records. The video outgoing-inspection provides visual verification of: 1) Final product appearance and surface quality. 2) Measurement verification using precision tools. 3) Edge quality assessment. 4) Packaging process showing protection methods. 5) Quantity verification. Together, these provide comprehensive quality assurance for your industrial cutting blades before shipment.
We ensure blade compatibility through: 1) Precision reverse engineering when physical samples are provided. 2) Comprehensive database of blade specifications for common crusher and granulator models. 3) CAD verification - creating detailed drawings for customer approval before production. 4) Dimensional tolerance control maintaining strict manufacturing tolerances (typically ±0.05mm to ±0.1mm). 5) Test fitting protocols for first-time custom orders. 6) Material certification to ensure proper hardness and properties. For OEM replacement blades, we match or exceed original specifications to ensure perfect fit and performance in your industrial size reduction equipment.
Our 3-month warranty offers significant advantages over typical industry warranties: 1) Extended coverage period - Many manufacturers offer only 30-60 days. 2) Comprehensive coverage - Includes defects in materials and workmanship under normal operating conditions. 3) Performance guarantee - Ensures blades meet specified hardness and dimensional tolerances. 4) Quick resolution - We process valid warranty claims promptly, typically within 7-10 days. 5) Transparent process - Clear guidelines for warranty claims with minimal bureaucracy. This extended warranty demonstrates our confidence in product quality and provides peace of mind for your industrial blade investment. Warranty claims require proof of purchase and evidence of the defect under normal use conditions.
Yes, we provide comprehensive technical support for: 1) Blade installation - Guidance on proper installation procedures, torque specifications, and alignment. 2) Troubleshooting - Assistance with common issues like uneven wear, premature dulling, or vibration. 3) Performance optimization - Recommendations for optimizing cutting efficiency based on your material mix. 4) Maintenance guidance - Proper sharpening techniques and frequency recommendations. 5) Compatibility verification - Confirming blade specifications match your equipment requirements. Support is available via email, phone, or video conference. For complex issues, we can analyze photos or videos of your equipment in operation. This ensures you achieve maximum performance and lifespan from your ShengAo plastic crusher blades.
