Crafted from premium materials for exceptional performance and durability

About Our Replacement Granulator & Crusher Blades

ShengAo precision-engineered replacement blades are the definitive solution for maintaining peak performance in Herbold, Zerma, Weima, and Cumberland granulators and shredders. As the core cutting edge of your recycling machinery, these blades are meticulously crafted to not only match but often exceed OEM specifications in durability and cutting efficiency. They are designed for the rigorous demands of reducing materials for recycling, disposal, or further processing, ensuring your operation runs smoothly with minimal downtime.

Unmatched Quality Assurance: Every ShengAo blade is backed by a comprehensive 1.5-year warranty, an industry-leading commitment that underscores our confidence in product longevity. We further ensure transparency and reliability through mandatory machinery test reports and video outgoing-inspection for every order.

Premium Material & Construction

We utilize a selection of premium steels to deliver optimal performance for specific applications. Our standard offerings include High-Speed Steel (HSS) and Alloy Tool Steel, both known for their superior wear resistance and toughness. We achieve a precise and consistent hardness of 58-60 HRC through controlled heat treatment processes, striking the perfect balance between edge retention and resistance to chipping.

Material & Finish Excellence: High-Speed Steel (HSS) Alloy Tool Steel Fully Customized Steel

Each blade undergoes precision grinding to achieve an exceptional surface finish of Ra 0.4 or less and a critical flatness of 0.01 or less. This meticulous manufacturing ensures a razor-sharp, burr-free cutting edge, minimizes friction, reduces heat buildup, and guarantees consistent, high-quality output from your granulator or crusher.

ISO 9001 Certified Manufacturing Process

Frequently Asked Questions (FAQ)

Find quick answers to common queries about replacement granulator and crusher blades.

Are ShengAo blades compatible with my Weima or Cumberland granulator?
Yes, absolutely. ShengAo specializes in manufacturing replacement shredder blades that are precision-engineered to be fully compatible with major brands including Herbold, Zerma, Weima, and Cumberland. We ensure dimensional accuracy, correct bolt patterns, and material properties that match or exceed OEM specifications for a perfect fit and optimal performance.
What is the lead time for a custom blade order?
For standard compatibility orders, lead times are: 1-10 pieces: 35 days. For orders over 10 pieces, the lead time is to be negotiated based on complexity and volume. Custom OEM/ODM projects typically require detailed consultation to determine the precise timeline, ensuring we meet your specific "granulator blade" requirements without compromising on quality.
What does the 1.5-year warranty cover?
Our industry-leading 1.5-year warranty covers defects in materials and workmanship under normal operating conditions. It is a testament to our confidence in the durability of our HSS and alloy tool steel blades. For specific terms and claim procedures, please refer to our warranty documentation. This extensive coverage is a key reason we are a trusted supplier for "crusher blades".
Can you provide blades for shredding copper cable and wire?
Yes. Our blades made from high toughness alloy tool steel with a hardness of 58-60 HRC are well-suited for processing copper recycling applications, including cable and wire granulation. The material combination provides the necessary wear resistance and strength to handle the abrasive nature of copper without excessive edge degradation.
What is included in the "video outgoing-inspection"?
Prior to shipment, we conduct and record a comprehensive inspection for your order. This video outgoing-inspection typically shows checks for critical parameters like final dimensions, edge sharpness, surface finish (Ra 0.4), flatness (0.01), hardness spot checks, and visual surface quality. This provides you with transparent, verifiable proof of quality and conformity before the blades leave our ISO 9001 certified facility.
Do you offer technical support after installation?
Yes, we provide comprehensive after-sales support. This includes video technical support to assist with installation or troubleshooting and ongoing online support. Our service extends beyond the warranty period, ensuring you have access to expert advice to maximize the performance and lifespan of your "plastic wood copper crusher blades".
What is the significance of a Ra 0.4 surface finish?
A superior surface finish of Ra 0.4 or less (a very smooth surface) is critical for high-performance blades. It minimizes friction during cutting, which reduces heat generation and power consumption. It also prevents material adhesion (e.g., sticky plastics), ensures cleaner cuts, and contributes to longer blade life by reducing microscopic stress points where cracks can initiate.
Is the MOQ really 1 piece, and how are they packaged?
Yes, our Minimum Order Quantity (MOQ) is a single item, allowing you to test our quality or replace individual blades with minimal commitment. Each blade is carefully packaged for protection. The typical single package size is 36x10x0.1 cm, with a gross weight of 0.060 kg. For larger orders, we use robust export packaging to ensure safe delivery worldwide.
