Raw Materials & Alloys

Crafted from premium materials for exceptional performance and durability

About Our Single Shaft Shredder Blades

The single shaft shredder rotor blade and counter blade are the core component of the shredder. They are used in various applications across different industries to reduce the size of materials for easier handling, recycling, disposal, or processing. Our custom-made single shaft shredder blades, available in premium SKD-11 and D2 tool steel, are engineered for maximum performance and durability in demanding industrial environments. These high-precision blades ensure efficient size reduction for plastic recycling, rubber processing, and waste management operations worldwide.

Premium Material & Construction

Our blades are primarily manufactured from SKD-11 and D2 Tool Steel, superior grades known for their exceptional wear resistance and toughness. These materials ensure high rigidity and impact resistance, making the blades ideal for shredding challenging materials. We also offer customization with 6CrW2Si, 42CrMo, DC53, LD, and Cr12MoV tool steels upon request. Each blade undergoes precise heat treatment to achieve HRC 60-62 hardness and features a high-precision, burr-free surface for smooth operation and consistent cutting performance in industrial shredding machines.

Key Features & Benefits

Designed for a long service life, these blades excel in demanding environments. Their high wear-resistant properties significantly reduce downtime for blade changes, while their impact-resistant design handles unexpected hard objects. The high rigidity prevents bending and deformation under heavy load, ensuring stable and efficient shredding output over extended periods. Key benefits include easy operation, competitive pricing, high-accuracy cutting, and reduced maintenance costs for your plastic shredder or industrial recycling equipment.

Application Industries & Materials

These versatile single shaft shredder blades are perfect for a wide range of size reduction tasks. They are highly effective in processing plastics (including hard plastics and lumps), various textiles, films, rubber, tires, wood, metal, circuit boards, and other recyclable or waste materials. Industries such as recycling, waste management, manufacturing, and textile processing will find these blades to be a reliable solution for their industrial shredding needs. They are compatible with most single shaft shredder machines on the market.

Customization & Quality Assurance

We specialize in providing tailor-made blade solutions. From dimensions to material specifications, we can customize the blades to fit your specific single shaft shredder model and material stream. Our commitment to quality is demonstrated through provided video outgoing-inspection and official machinery test reports, giving you confidence in every purchase. Backed by a 1-year warranty and packed securely in wooden cases, the blades arrive ready for installation. With a Minimum Order Quantity (MOQ) of just 10 pieces and support for OEM/ODM, we offer flexible solutions for all business sizes.

Frequently Asked Questions (FAQs)

Find expert answers to common questions about ShengAo SKD-11/D2 Single Shaft Shredder Blades for plastic recycling, industrial waste processing, and size reduction applications.

SKD-11 (Japanese JIS standard) and D2 (American AISI standard) are both high-carbon, high-chromium cold work tool steels with very similar chemical compositions and properties. Both are excellent choices for industrial shredder blades due to their high wear resistance and good toughness after heat treatment. The primary difference lies in their origin standards. In practice, both achieve a hardness of HRC 58-62 and perform exceptionally well in plastic recycling and rubber shredding applications. At ShengAo, we use both grades interchangeably based on customer preference and material availability, ensuring top performance for your single shaft shredder machine.
Compatibility is determined by three key dimensions: Outer Diameter (OD), Inner Diameter (ID), and Thickness. The best way is to check your shredder's manual or measure an existing blade. Common sizes include 34x34x20mm, 40x40x20mm, and 50x50x25mm. You can also provide your shredder's make and model, and our technical team can match it with our database. For non-standard sizes, we offer full custom OEM shredder blade manufacturing. Simply send us a sample, drawing, or precise specifications, and we will produce blades that fit your machine perfectly for optimal plastic waste recycling efficiency.
The lifespan of SKD-11 shredder blades varies based on the material processed, shredder load, and maintenance. For common plastics like PET, HDPE, and LDPE, you can expect several hundred to over a thousand hours of operation before requiring sharpening or replacement. For more abrasive materials like glass-filled plastics, rubber, or circuit boards, lifespan will be shorter. Our HRC 60-62 hardness treatment maximizes wear resistance. Proper installation, correct blade clearance, and avoiding metal contamination are key to extending blade life. Many of our customers report a 30-50% longer service life compared to standard blades, reducing overall industrial blade replacement costs.
Currently, we focus on manufacturing new, high-quality shredder knives and do not offer a dedicated blade sharpening service. However, SKD-11/D2 blades can be professionally sharpened multiple times to extend their life. We recommend using a qualified local service with experience in tool steel grinding to ensure the correct angle and finish are maintained without compromising the heat treatment. For consistent performance, many customers find it more cost-effective to keep a set of spare blades on hand and order replacements from us with our competitive pricing and 40-day lead time for standard orders.
Our commitment to quality includes two key deliverables: 1) Video Outgoing-Inspection: A custom video showing your blades, verifying dimensions, surface finish, and visual quality before packing. 2) Machinery Test Report: A document certifying the material grade and hardness (HRC) achieved. We back our blades with a comprehensive 1-year warranty against manufacturing defects in material and workmanship. This warranty covers issues like premature cracking or abnormal wear under normal operating conditions for plastic and rubber shredding. It does not cover damage from improper installation, metal contamination, or processing of unsuitable materials.
Absolutely. Customization is our specialty. For shredding highly abrasive or tough materials like tires, cables, or thin metals, we recommend different material grades or treatments. While SKD-11/D2 is excellent for most plastics and rubber, we might suggest 6CrW2Si for higher impact resistance or a different heat treatment protocol. We can adjust the blade geometry (hook angle, cutting edge) to optimize for specific material tearing or shearing. For true metal shredding, we would discuss alternative materials. Simply inform us of your target material, and our engineers will propose the best custom shredder blade solution for your application.
We offer flexible payment terms: typically T/T (Bank Transfer) with 30% deposit and 70% balance before shipment. For established customers, other terms can be discussed. We ship worldwide via reliable couriers like DHL, FedEx, UPS for samples and small orders, and by sea for large, heavy orders to optimize cost. All blades are securely packed in wooden cases to prevent damage during transit. Shipping costs and times depend on order quantity, weight, and destination. We provide a detailed quote including all logistics and customs documentation support to ensure smooth delivery of your industrial shredder spare parts.
The 40-day lead time ensures we deliver the highest quality blades. This period includes: 1) Material procurement of genuine SKD-11/D2 steel bars. 2) Precision machining (cutting, milling, drilling) to your specifications. 3) Critical heat treatment (quenching and tempering) to achieve HRC 60-62, which requires controlled cycles. 4) Precision grinding and finishing for exact dimensions and sharp edges. 5) Rigorous quality inspection and documentation. Rushing these processes can compromise blade performance and longevity. For urgent needs, please contact us—we may have standard sizes in stock or can explore expedited options for your recycling business operations.
