Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo Heavy-Duty Granulator Knives & Crusher Blades for plastic recycling, rubber processing, and industrial size reduction applications.

D2 steel is a high-carbon, high-chromium tool steel offering excellent wear resistance and good toughness, ideal for general plastic and rubber recycling. M2 steel is a molybdenum-based high-speed steel that maintains hardness at elevated temperatures, perfect for high-speed operations. 52100 steel is a high-carbon chromium bearing steel with exceptional hardness and wear resistance, suitable for highly abrasive applications. For most plastic recycling operations, D2 provides the best balance of performance and cost. M2 is recommended for high-speed granulators, while 52100 excels in processing highly abrasive materials. Our technical team can recommend the optimal material for your specific industrial recycling application.
Our manufacturing processes achieve superior tolerances through several measures: 1) Precision CNC machining with advanced equipment capable of micron-level accuracy. 2) Enhanced quality control with multiple inspection stages throughout production. 3) Superior material selection with consistent metallurgical properties. 4) Advanced heat treatment processes that minimize distortion. 5) Precision grinding operations that achieve surface finishes and dimensional accuracy beyond standard requirements. This results in blades that fit more precisely, balance better, and perform more consistently than typical OEM parts. For customers with specific tolerance requirements for their industrial granulator equipment, we can implement even tighter tolerances upon request.
Our quality documentation includes: Machinery Test Report: A formal document providing material certification, hardness test results (HRC), dimensional inspection data with actual measurements, surface finish analysis, and visual inspection findings. Video Outgoing-Inspection: A custom video showing: 1) Visual examination of blade surfaces and cutting edges, 2) Live dimensional measurement verification, 3) Close-up inspection of critical features, 4) Hardness testing demonstration (if applicable), 5) Packaging process documentation. This combination provides both certified documentation and visual verification that your blades meet all specifications before shipment, ensuring quality and compliance for your industrial recycling equipment parts.
Our 15-day lead time for orders of 1-100 pieces represents an efficient production schedule: 1) Material Preparation: Immediate sourcing of required steel from our strategic inventory. 2) Precision Machining: CNC operations completed within 5-7 days. 3) Heat Treatment: Controlled hardening and tempering processes (2-3 days). 4) Precision Grinding: Final dimensioning and edge preparation (3-4 days). 5) Quality Inspection: Comprehensive testing and documentation (1-2 days). 6) Packaging and Shipping Preparation: Secure packing in durable ply-wooden boxes. This timeframe begins from order confirmation and deposit receipt. For larger orders (>100 pieces), we establish custom production schedules to optimize efficiency while maintaining quality standards for industrial blade manufacturing.
We offer extensive customization options with a minimum order of 10 pieces: 1) Customized Logo: Laser engraving or etching of your company logo, part numbers, or identification marks. 2) Customized Packaging: Branded boxes, specialized packing materials, or specific shipping requirements. 3) Graphic Customization: Additional markings, instructional graphics, or safety indicators. 4) Blade Design Customization: Modifications to dimensions, edge geometries, mounting features, or special configurations. 5) Material Customization: Selection from D2, M2, 52100, or other specialized alloys. Customization fees are determined based on specific requirements and complexity. We work closely with customers to implement features that enhance their industrial equipment branding and operational efficiency.
Yes, our heavy-duty blades are specifically designed for both plastic and rubber recycling applications, but with important considerations: 1) Material Selection: D2 steel is generally suitable for both, while specialized rubber applications might benefit from specific edge geometries. 2) Edge Design: Rubber processing may require different cutting angles or edge preparations compared to plastic. 3) Equipment Compatibility: Ensure your granulator or crusher is designed for the specific material characteristics. 4) Operating Parameters: Different RPM, feed rates, and temperature considerations may apply. While our standard blades work well for both materials, we recommend discussing your specific application with our technical team to optimize blade design for your particular plastic and rubber processing needs.
Our 3-month warranty provides coverage for: 1) Manufacturing Defects: Flaws in materials or workmanship. 2) Premature Failure: Unexpected early failure under normal operating conditions. 3) Dimensional Inaccuracies: Blades not meeting specified dimensions and tolerances. 4) Material Issues: Problems with steel quality or improper heat treatment. The warranty does not cover normal wear and tear, damage from improper installation or operation, processing of inappropriate materials, accidents, or modifications made after purchase. This warranty period is designed to provide assurance of quality for your investment in industrial recycling equipment parts while recognizing that blades are consumable items subject to normal wear in operation.
For optimal performance of your industrial granulator blades: Installation: 1) Clean all mounting surfaces thoroughly before installation. 2) Follow manufacturer torque specifications precisely. 3) Ensure proper blade-to-counter blade clearance (typically 0.1-0.3mm). 4) Check rotor balance after installation. 5) Verify all fasteners are properly secured. Maintenance: 1) Regularly inspect blades for wear, damage, or dulling. 2) Monitor particle size consistency as an indicator of blade condition. 3) Keep blades clean of material buildup. 4) Sharpen blades before they become excessively dull. 5) Rotate double-edged blades when one edge becomes worn. 6) Implement effective metal detection to prevent damage from contaminants. Proper installation and maintenance maximize blade life and ensure efficient operation of your plastic and rubber recycling equipment.
