Raw Materials & Alloys

Crafted from premium materials for exceptional performance and durability

About Our High-Performance Rubber Cutting Blades

The rotor and counter blades are the core components of any single shaft shredder, directly responsible for the cutting efficiency and output quality. Specifically engineered for the demanding task of tire, rubber, and plastic recycling, our heavy-duty blades are precision-crafted to deliver maximum performance in high-impact, high-wear environments. Built for longevity and consistent cutting action, they ensure optimal size reduction of tough materials into uniform granulate for further processing or recycling.

Premium Material & Construction

Our blades are manufactured from premium Tool Steel grades, primarily D2/SKD11, which are renowned for their exceptional wear resistance and ability to maintain a sharp edge under heavy load. This high-chromium, high-carbon steel is heat-treated to achieve a hardness of HRC 56-63, providing the perfect balance between hardness for wear resistance and toughness to prevent chipping. Each square blade undergoes precision CNC machining and grinding to achieve a dimensional tolerance within ±50 microns, ensuring a high-precision, burr-free cutting surface. This precision is critical for consistent cutting performance, smooth operation, and maintaining the efficiency of your plastic and rubber recycling machinery.

Key Features & Operational Benefits

The cornerstone of our blades is their ability to deliver a long service life in the most abrasive applications. The high wear resistance of D2/SKD11 steel dramatically extends intervals between sharpening or replacement, minimizing costly machine downtime and maintenance. The high hardness (HRC 56-63) ensures the cutting edge stays sharp longer, maintaining high cutting efficiency and consistent particle size. Furthermore, the robust construction provides high rigidity and impact resistance, preventing deformation and allowing the blades to handle the extreme forces encountered when shredding tires, dense rubber blocks, and hard plastics. This combination translates directly to increased productivity and lower total cost of ownership.

Application Industries & Materials

These high-performance rubber cutting blades are purpose-built for the recycling industry's most challenging materials. They excel in processing whole tires (car and truck), rubber scraps and trimmings, EPDM, silicone, industrial rubber products, hard plastics (HDPE, PP, PVC lumps), and plastic purgings. Key industries that depend on their reliability include tire recycling plants, rubber product manufacturers, plastic recycling facilities, and waste management operations focused on ELT (End-of-Life Tire) processing. Whether installed in a primary shredder or a fine granulator, these blades provide the durable cutting solution needed to transform tough, elastic, and abrasive materials into valuable secondary raw materials.

Customization & Quality Assurance

We specialize in providing completely customized blade solutions. From the overall size and thickness to the bore hole pattern and cutting edge geometry, we manufacture blades to fit your specific single shaft shredder model perfectly. Our commitment to quality is transparent and verifiable. We provide an official machinery test report and a video outgoing-inspection for every order, allowing you to verify quality before shipment. Backed by a solid 6-month warranty, your investment is protected. Blades are securely packed in carton boxes inside sturdy wooden cases to ensure they arrive at your facility undamaged and ready for immediate installation and peak performance.

Frequently Asked Questions (FAQs) - Rubber Cutting Blades

Find expert answers to common questions about ShengAo High-Performance Rubber Cutting Blades for single shaft shredders in tire, rubber, and plastic recycling.

D2/SKD11 tool steel is considered optimal for tire and rubber shredding blades due to its exceptional combination of properties. It is a high-carbon, high-chromium steel that offers: 1) Superior Wear Resistance: The primary requirement for shredding abrasive materials like tire rubber filled with carbon black and silica. 2) High Hardness (achievable up to HRC 62-63): Maintains a sharp cutting edge for clean shearing, reducing power consumption and heat generation. 3) Good Toughness: Provides enough resistance to chipping when encountering steel belts or bead wires in tire recycling. This balance ensures a long service life and consistent performance, directly lowering the operational cost per ton in rubber recycling machinery.
The hardness range of HRC 56-63 is strategically chosen for plastic and rubber recycling blades. A hardness around HRC 56-58 offers excellent toughness, making blades more resistant to chipping when processing dense plastic lumps or encountering contaminants. A higher hardness of HRC 60-63 maximizes wear resistance, which is crucial for processing abrasive materials like filled plastics, glass-reinforced polymers, or tire rubber. Our standard heat treatment aims for the optimal balance within this range. For primarily plastic recycling, we might target the lower end for toughness; for dedicated tire shredding, we target the higher end for wear resistance. This precise control ensures the blade lasts longer and maintains high cutting efficiency in your specific application.
Yes, our square rubber cutting blades are specifically engineered to process whole passenger car tires (ELTs) in robust single shaft shredders. The square design provides multiple cutting edges, allowing rotation for extended life. The D2/SKD11 material and HRC 56-63 hardness provide the necessary toughness to absorb the impact of the initial tire engagement and the wear resistance to handle the highly abrasive rubber and fabric/steel cord. However, successful shredding also depends on having a shredder with sufficient power, a properly designed cutting chamber, and often pre-processing (sidewall removal). We recommend consulting with us about your specific machine model to ensure our blade geometry and hardness are perfectly matched for your tire recycling application.
Our official machinery test report is a comprehensive quality document that provides verifiable data on your blades. It typically includes: 1) Material Certification: Confirmation of the steel grade (e.g., D2/SKD11). 2) Hardness Test Results: Documentation of Rockwell C (HRC) hardness measurements taken at multiple points on the blade to ensure uniformity (e.g., HRC 58, 59, 60). 3) Dimensional Inspection Record: Verification of critical dimensions (thickness, width, hole diameter) against your drawing, confirming the ±50 micron precision. 4) Visual Inspection Notes: Confirmation of surface finish and absence of major defects. This report serves as your formal quality assurance and is essential for traceability and validating the specifications of your industrial spare parts.
The square blade design offers significant operational and economic advantages for single shaft shredders. The primary benefit is that it provides four usable cutting edges. When one cutting edge becomes dull from wear, the blade can be rotated 90 degrees (or 180 degrees for double-sided use) to present a fresh, sharp edge to the material. This effectively quadruples the service life between blade sharpenings or replacements. This feature drastically reduces machine downtime for maintenance, lowers the inventory cost of spare blades, and simplifies blade management for operators. It is particularly cost-effective in high-wear applications like tire and rubber recycling, where blade edges degrade faster.
Yes, a 15-day lead time for 1-100 pieces of custom-sized blades is our standard and achievable commitment for most orders. This efficiency is due to our streamlined manufacturing process, strategic stock of raw materials (D2/SKD11 steel blanks), and dedicated production scheduling for small to medium batches. The process includes: 1) Quick tooling setup based on your provided drawings. 2) Efficient CNC machining and grinding. 3) Controlled heat treatment in our own facility. 4) Final inspection and packing. The lead time starts after order confirmation and deposit receipt. For extremely complex first-time customizations, we will provide a transparent update if more time is needed. This fast turnaround minimizes your machine downtime waiting for critical replacement blades.
The dual-layer carton box + wooden case packaging is essential for protecting your high-value, high-precision industrial blades during international shipping. The inner carton box provides a clean, controlled environment. Each blade is typically wrapped in VCI (Vapor Corrosion Inhibitor) paper or oiled to prevent rust during transit. The carton separates blades and prevents edge-to-edge contact. The outer wooden case provides critical structural strength and impact resistance. It protects the contents from crushing, punctures, and severe handling that can occur during sea or road freight. The wooden case is also easily handled by forklifts. This robust packaging ensures your blades arrive in the same perfect condition they left our factory, ready for installation and delivering their promised long service life.
Providing specifications for a customized blade order is straightforward. We need clear information to ensure a perfect fit and performance. The best methods are: 1) Send an Original/Drawing: A technical drawing (PDF, DWG, DXF) with all dimensions, tolerances, hole sizes, and positional tolerances. 2) Send a Physical Sample: Mail us a worn or new blade from your machine. We can reverse-engineer it precisely. 3) Provide Machine Details: The make, model, and serial number of your single shaft shredder. We may have existing drawings for that model. 4) Material & Hardness Requirement: Specify if you want our standard D2/SKD11 (HRC 56-63) or a different grade. Our engineering team will then review, ask any clarifying questions, and provide a formal quote and drawing for your confirmation before production begins.
