1. Introduction to Industrial Blades
Industrial blades are critical tools widely used across various industries for cutting tough materials such as wires, leather, ropes, and thick paper. Typically manufactured from high-carbon steel, these blades are engineered for sharpness, durability, and reliability. This article provides a comprehensive overview of the production process, blade types, materials, technical parameters, usage scenarios, packaging methods, and common issues encountered in the production and application of industrial blades.
1.1 Industrial blade production video
2. Production Process of Industrial Blades
The manufacturing of industrial blades involves a series of precise steps to ensure the final product meets stringent quality standards. Below is a detailed breakdown of each stage.
2.1 Stamping
- Raw Material Inspection: Steel strips, the primary raw material, are tested for hardness and dimensional accuracy.
- Mold Installation: Molds are selected and installed based on the production order specifications.
- Stamping and Forming: The steel strip is stamped into the desired blade shape using adjusted and calibrated equipment.
- Dimension Verification: The formed blades are measured against customer-provided drawings. Only blades meeting specifications proceed to the next stage.
2.2 Heat Treatment (Quenching)
- Quenching: Blades undergo quenching at temperatures of 650°C, 750°C, 800°C, 820°C, 850°C, 870°C, 880°C, or 885°C (±20°C tolerance). This process includes preheating, quenching, crystal transformation, and forming to enhance hardness and wear resistance.
- Tempering: Blades are tempered at 200-250°C to relieve internal stresses and improve toughness.
- Hardness Testing: Unquenched steel strips have a hardness of HV 280-330, which increases to HV 700-780 post-quenching. Blades passing hardness inspection proceed with a production capacity of 10,000 pieces per hour.
- Laser Engraving: For customers requiring logos, laser engraving is performed after heat treatment.
2.3 Grinding
- Grinding Process: Eight grinding wheels perform rough, fine, and precision grinding to sharpen the blades, achieving a production capacity of 25,000 pieces per hour.
- Polishing: Burrs and rough edges from grinding are removed through polishing.
- Blade Cutting: Blades are separated into individual units.
- Edge Inspection: Blade edges are inspected every 30 minutes to ensure quality compliance.
- Note: Grinding is adjusted (rough, fine, or precision) based on customer cutting needs, with rough and precision grinding being the most common.
2.4 Oil Immersion
- Oil Soaking: Blades are immersed in rust-preventive oil for approximately 15 minutes to form a protective oil film, enhancing rust resistance.
- Oil Selection: Oil type and viscosity vary based on customer specifications.
- Oil Types: Two categories are available—food-grade and industrial-grade rust-preventive oils.
Note: For utility and trapezoidal blades, production concludes after oil immersion, followed by packaging per customer requirements.
2.5 Assembly (For Safety Blades)
- Preparation: Post-oil immersion, bare blades are transferred to the assembly workshop.
- Clip Arrangement: Stamped clips are organized and sent to the assembly area.
- Assembly: A proprietary clipping machine assembles bare blades with clips and installs protective paper.
- Manual Boxing: Assembled blades are packed manually according to customer specifications.
- Quality Check and Storage: Products passing quality inspection are stored in the warehouse, with stacking limited due to weight.
2.6 Packaging
- Packaging details are outlined in Section 6.
3. Types of Industrial Blades and Materials
The table below summarizes the types of industrial blades, their materials, and coating options:

Materials sourced from Korean POSCO (SK2, SK4, SK5) and domestic steel grades.
4. Parameters of Industrial Blades
Key performance metrics for industrial blades include thickness, hardness, sharpness, durability, and rust resistance (via salt spray testing). The table below compares these parameters:
| Blade Type | Parameter | Industry Min | Industry Avg | Our Standard | Industry Max |

| Hardness (HV) | 670 | 700-760 | 720-780 | 800 | |
| Sharpness (mm) | ≥20 (first cut) | – | – | – | |
| Durability (mm) | 40+ | 60 | 150 | 250 | |
| Salt Spray Test | Level ≥8 (4h) | – | – | – | |
| Trapezoidal Blades | Thickness (mm) | 0.58 | 0.58 | 0.6 | 0.6 |
| Hardness (HV) | 700 | 700-800 | 750-850 | 900 | |

8. Common Issues and Solutions
Rust Resistance and Storage Duration
- Question: How effective is rust resistance, and how long can blades be stored?
- Answer: Made from carbon steel, rust resistance depends on storage conditions. Salt spray tests (5% neutral, 3 hours) yield a level ≥8.
Minimum Order Quantity
- Question: What is the minimum order quantity?
- Answer: One ton of material produces 150,000-200,000 trapezoidal/utility blades or 300,000-500,000 safety blades.
Blade Quality Assessment
- Question: How is blade quality judged?
- Answer: Durability is the primary metric, given their use with hard materials.
Custom Mold Costs
- Question: What is the cost of custom mold development?
- Answer: Simple molds cost 6000-6500 RMB. Superior materials reduce burrs and defects compared to competitors (e.g., Ningbo).
