Introduction
Explore Shengao's high-speed steel (HSS) cutting knives, the reliable workhorse blades engineered for superior performance in the papermaking, packaging, printing, and plastic film industries. These knives are designed to deliver durable, precision cutting, enhancing efficiency in continuous industrial operations. They represent an optimal balance of toughness, wear resistance, and cost-effectiveness for a wide range of material processing applications.
2. Shengao High-Speed Steel Cutting Knives: Features & Functions
Shengao's high-speed steel cutting knives are composite materials engineered for reliability. The base is high-speed steel with good strength and toughness, while the surface layer is a high-hardness, high-wear-resistant material, making them versatile for various industrial cutting tasks.
2.1. Premium High-Speed Steel Material
Shengao utilizes mainstream high-speed steel such as M2 (SKH-51/SKH-9), M35, and M42. The hardness of high-speed steel tools typically ranges from 62 HRC to 70 HRC (766 HV to 1037 HV). Through physical vapor deposition (PVD) coating of a thin TiN (Titanium Nitride) or TiC layer (2-6 micrometers), the surface hardness can be significantly increased to 2000 HV-3200 HV (exceeding 83 HRC). This enhances the tool's surface heat resistance to over 1000°C, allowing cutting speeds to be increased by 50% to 100% and tool life extended by 2 to 10 times. The coating also reduces friction, resists abrasive and adhesive wear, and can lower cutting forces by 20%-40% and cutting heat by about 20%.
2.2. Precision Engineering for Clean Cuts
The knives undergo precision grinding to ensure sharp and smooth cutting edges. This precision engineering is crucial for achieving clean cuts on materials like paper, cardboard, and plastic films without fraying or producing excessive dust. Proper blade geometry and sharpness contribute to reducing the cutting force required, which can lower the overall energy consumption of the machinery and minimize material deformation, especially important for thin and delicate substrates.
2.3. YouTube Video Demonstration
This video showcases Shengao's high-speed steel cutters efficiently processing rolls of packaging material and paperboard. Key observations include the smooth, uninterrupted operation, the clean, burr-free edges on the cut materials, and the consistent performance throughout the demonstration, highlighting the blade's reliability and sharpness retention.
3. Blade Design and Customization Support
Shengao offers a range of standard high-speed steel knife designs while emphasizing strong customizability to meet specific machine specifications and unique material cutting challenges encountered by clients.
3.1. Standard Blade Designs and Schematics

Shengao produces various standard knife types, including straight blades for bag machines, circular blades for cross-cutting, and tungsten steel circular knives for heavier-duty applications. Technical schematics detail critical dimensions like diameter, thickness, bore size, and bevel angles. The choice of angle, for instance, is tailored to the material: a sharper angle is optimal for cleanly slicing through paper and film, while a more robust angle provides strength for cutting thicker cardboard or plastic stacks.
3.2. Custom Design and Development Services
A core strength of Shengao is its customization capability, supporting OEM and ODM services. Clients can request modifications to standard dimensions to fit non-standard machinery, adjustments to the blade's edge geometry for specific materials (e.g., optimizing for anti-stick coatings when cutting adhesive films), or select from different HSS grades. Customers can provide their own drawings or samples. Shengao's technical team collaborates to modify designs for improved performance and longevity, ensuring the blade meets the specific application needs.
4. Primary Industry Applications
Shengao's high-speed steel cutting knives are versatile tools designed for reliability across several key industries involved in converting and processing flexible and semi-rigid materials.
4.1. Paper and Cardboard Cutting
In paper mills and converting plants, Shengao knives are used for precision slitting and sheeting of paper rolls, cutting cardboard, and processing corrugated board. The high wear resistance of the blades ensures consistent cut quality and long intervals between sharpening, which is crucial for high-volume production lines. The clean cuts prevent dust and paper fraying, maintaining product quality.
4.2. Flexible Packaging and Plastic Film Processing
These knives are widely used in the packaging industry for cutting and sealing plastic films, such as PE, PP, and BOPP, used in bags and pouches. They are integral to bag-making machines. The knives' ability to maintain a sharp edge is essential for producing clean seals and precise cuts on these often thin and delicate materials without tearing or generating excessive heat that could melt the film.
4.3. Printing and Label Industries
For the printing and label sectors, precision is paramount. Shengao blades are used for cutting labels, tapes, and other printed materials. The sharp, durable edge ensures accurate, clean cuts without damaging the printed surface or the adhesive backing, which is vital for the final product's appearance and functionality.
5. Comparative Analysis: Shengao vs. Other Major Brands
When selecting industrial cutting knives, buyers often evaluate several options. The following table provides a simplified comparison based on common market offerings.
Feature | Shengao Blades | Typical Competitor A (Generic Brands) | Typical Competitor B (Premium Brands) |

6. Maintenance, After-Sales Support, and Durability
Proper maintenance and reliable support are key to maximizing the value of your investment in cutting knives.
6.1. Routine Maintenance Guidelines
Effective maintenance prolongs blade life and ensures consistent cut quality. Key practices include:
- Regular Cleaning: Clean blades periodically to remove residue from paper dust, plastic particles, or adhesives, which can impair cutting performance and cause corrosion.
- Edge Inspection and Sharpening: Regularly inspect the cutting edge for dullness or minor damage. Timely sharpening restores performance. Under normal conditions, Shengao's coated HSS blades offer a significantly extended service life before requiring resharpening compared to uncoated tools.
- Proper Storage: Store blades in a dry environment to prevent rust. Use protective edge covers when not in use.
