Introduction to Circular Blades
Circular blades are round cutting tools designed for precision slicing, trimming, and slitting operations across various industries. These blades are characterized by their circular shape with a central mounting hole for secure attachment to machinery. They are engineered to provide minimal cutting resistance and maximum wear resistance, making them ideal for processing materials like paper, films, foils, and plastics. The versatility of circular blades stems from their ability to maintain consistent cutting performance while withstanding continuous operational demands in industrial environments. Shengao's circular blades represent a balance of practical engineering and cost-effectiveness, delivering reliable performance for universal industrial applications without the premium cost of highly specialized precision tools.
2. Shengao Circular Blades: Features & Functions
Shengao's circular blades are workhorse components designed for reliability and efficiency in demanding production environments. They serve as versatile cutting solutions optimized for papermaking, packaging, printing, and plastic film industries, where consistent performance is more critical than extreme precision. Our blades are engineered to reduce downtime and maintenance costs while delivering clean, precise cuts across a wide range of materials.
2.1. Premium Material Composition
The foundation of Shengao's blade performance lies in our careful material selection. We primarily utilize 440C stainless steel for applications requiring corrosion resistance and consistent performance. This material contains approximately 1.2% carbon with chromium content of 16-18%, offering excellent anti-rust properties while maintaining sufficient hardness for most industrial cutting applications. For more demanding applications, we employ materials like Cr12mov, W6Mo5Cr4V2, and W18Cr4V, which provide enhanced wear resistance and edge retention. Through specialized heat treatment processes including deep cryogenic treatment, our blades achieve hardness levels between HRC 57-61, creating an optimal balance between toughness and sharpness retention for extended operational life.
2.2. Precision Engineering for Optimal Performance
Shengao blades undergo precision grinding processes to ensure consistent cutting performance across all production runs. Our engineering focus emphasizes practical efficiency improvements, particularly the ability to handle higher feed rates compared to standard blade shapes. For instance, when processing flat surfaces without steps, circular blades can increase feed rates by approximately 2.6 times compared to conventional blade shapes while maintaining equivalent surface finish quality. This efficiency gain translates directly to higher production throughput and reduced cycle times. The continuous cutting edge of circular blades also allows for indexable use as sections wear, maximizing utilization before resharpening is required. This design is particularly advantageous for operations processing non-metallic materials like paper, cardboard, and plastic films where extreme hardness is less critical than consistent sharpness and clean cutting action.

4. Primary Industry Applications
Shengao circular blades serve as industry-universal components with particular strength in several key sectors where reliability and cost-effectiveness are prioritized over extreme precision.
4.1. Papermaking Industry
In paper manufacturing and conversion, Shengao circular blades are extensively used for precision slitting and trimming operations. They handle various paper grades from lightweight tissues to heavy cardboards with consistent cutting performance. The blades' design minimizes resistance during cutting, reducing energy consumption while maintaining clean edges that prevent dust generation. Applications include rotary slitters for parent rolls, precision trimmers for finished product sizing, and scrap reduction systems for recycling paper waste. The durability of our blades ensures consistent performance throughout extended production runs, maintaining dimensional accuracy in the final paper products.
4.2. Packaging and Printing
Packaging converters rely on Shengao circular blades for processing corrugated boards, folding cartons, and various flexible packaging materials. Our blades deliver precise cutting for post-print slitting, carton blanking, and flexible packaging conversion. The consistent cutting quality ensures clean edges on printed materials without jagged edges or material deformation that could compromise package integrity or appearance. For corrugated board processing, our specially engineered blades handle the abrasive nature of paperboard while maintaining sharpness through extended production runs. In printing operations, the precision of our blades ensures accurate registration maintenance during finishing operations.
4.3. Plastic Film and Foil Processing
Shengao blades excel in processing flexible materials including plastic films (PP, PE, PET), aluminum foil, and laminated structures used in packaging. We offer both single-sided and double-sided sharpened blades, with double-edged versions particularly suited for thin materials below 70μm thickness where edge cleanliness is critical. Our blades maintain precise cutting angles that prevent material stretching or deformation during slitting operations. For challenging materials like composite films with metalized layers or adhesive coatings, we provide specialized edge geometries that reduce buildup and prevent premature blade degradation. The application precision directly impacts product quality, particularly in industries like capacitor manufacturing or food packaging where edge quality affects both functionality and aesthetics.
4.4. Other Major Applications
Beyond our core markets, Shengao circular blades serve numerous other industries including textile processing (fabric cutting and trimming), rubber manufacturing (strip cutting and blanking), foam conversion (precision slitting), and food processing (product portioning). The versatility of our standard blade designs allows for adaptation across multiple industries with minimal customization, while our specialized options address unique material challenges in sectors like pharmaceutical packaging, non-woven fabric production, and electrical insulation manufacturing. This breadth of application experience enables us to provide practical solutions based on proven performance across diverse operating conditions.
