2. Shengao Crusher Blades: Features & Functions
Shengao's crusher blades are engineered for reliability and efficiency in demanding industrial environments. They are designed as versatile workhorse components suitable for a wide range of plastic processing applications, from recycling post-consumer waste to handling manufacturing scrap.
2.1. Premium Material Composition
The core of Shengao's blade performance lies in the selection of robust materials. Primarily manufactured from high-carbon steel and alloy tool steels like SKD11 and D2, these blades achieve a Rockwell Hardness (HRC) of 58-62. This specific hardness range is critical as it provides an exceptional balance between wear resistance and toughness, ensuring the blades can withstand the impact of crushing rigid plastics like PET bottles and ABS scraps without chipping or deforming prematurely. The advanced heat treatment processes further enhance the blade's toughness and edge retention, allowing them to maintain sharpness over extended periods.
2.2. Precision Engineering for Optimal Performance
Shengao blades are subject to precision grinding using CNC machinery to ensure razor-sharp cutting edges. This precision is not just about sharpness; it directly translates to operational benefits. A precisely sharp blade reduces the force needed to cut, leading to lower energy consumption for the entire crusher. Furthermore, it ensures a uniform particle size of the output granules, which is crucial for efficient melting and pelletizing in downstream processes. The blades are also dynamically balanced to minimize vibration during operation, which contributes to smoother running and reduced wear on the crusher's bearings and other components.

3. Blade Design Diagrams and Customization Support
Shengao understands that a one-size-fits-all approach is ineffective in the diverse plastic processing industry. Therefore, the company offers a range of standard designs while emphasizing strong customizability to meet specific machine requirements and material challenges.
3.1. Standard Blade Designs and Technical Schematics
Shengao produces a variety of standard blade types to suit different crusher configurations and material types. These include straight Rotor Blades (rotating knives), Stator Blades (fixed knives), and specialized designs like Claw Blades for tearing tough, bulky materials. The company provides clear technical schematics for each standard model, detailing critical dimensions such as length, width, thickness, and bore diameter, as well as the precise blade angle. The blade angle is particularly important; a sharper angle is optimal for cleanly cutting soft plastics, while a blunter angle provides more strength for crushing hard plastics.
3.2. Custom Design and Development Services
The cornerstone of Shengao's service is its customization capability. The company supports OEM and ODM services, allowing clients to tailor blades to their exact needs. This includes customizing dimensions to fit non-standard machine models, adjusting the blade angle or tooth shape for specific materials (e.g., saw-tooth edges for film or smooth edges for sticky plastics), and selecting specialized materials for unique applications. Customers can provide their own drawings, sketches, or even samples for reverse engineering. Shengao's technical team can also assist in modifying existing designs to improve performance and longevity, offering a collaborative approach to problem-solving.
4. Primary Industry Applications
Shengao plastic crusher blades are industry-universal components designed for reliability across several key sectors within the plastic economy.
4.1. Virgin Plastic Pelletizing (New Plastic Granulation)
In the production of new plastic products, crushers are used to process off-specification items, injection molding runners, and production scrap directly at the manufacturing site. Using Shengao blades in this closed-loop recycling system ensures efficient size reduction of these materials into uniform regrind flakes. This regrind can be blended with virgin pellets and fed back into the production line, significantly reducing raw material costs and minimizing waste. The durability of Shengao blades is key here, as they maintain consistent particle size over long periods, which is essential for maintaining the quality of the final product.
4.2. Recycled Plastic Granule Production
This is the most demanding application, where blades encounter contaminated and mixed plastics. Shengao blades are widely used in dedicated plastic recycling facilities to crush post-consumer items like PET bottles, HDPE containers, and PVC pipes into flakes for washing, sorting, and final pelletizing. Their robust wear resistance allows them to handle abrasive materials and occasional contaminants, reliably processing material before requiring maintenance. The ability to produce a consistent flake size is critical for achieving high-quality recycled pellets that can compete with virgin materials.
4.3. Injection Molding and Manufacturing Scrap Recycling
Every injection molding, blow molding, or extrusion operation generates scrap—sprue, runners, rejected parts. On-site granulation is the most cost-effective way to manage this. Shengao blades are perfectly suited for this task, offering the toughness needed to handle thick, often glass-filled sprues and parts. Their reliable performance ensures a steady supply of clean regrind, maximizing material utilization and improving the overall sustainability of the manufacturing process.
4.4. Film and Bag Recycling
Processing lightweight and flexible materials like PE films and PP woven bags presents a unique challenge, as they can easily wrap around rotating components. Shengao offers blades with designs suited for this task, such as specific tooth shapes, which grab and cut these materials efficiently without jamming. This capability supports the recycling of agricultural film, silage wrap, and supermarket bags, promoting sustainability in sectors that generate large volumes of flexible plastic waste.
