The production process of blades mainly includes different materials and changes in usage requirements. For example, the manufacturing process of hard alloy blades requires an additional sintering step to melt the pressed powder into hard alloy, a material with extremely high hardness. There are also some blades made of special materials, and their production process will be more complex, requiring specialized equipment and technology. The production process of blades can be divided into several main steps, and the detailed process is introduced below.
1. Material preparation
Firstly, select the appropriate material based on the requirements of the blade's usage properties. This includes considering factors such as hardness and sharpness, as well as whether rust prevention, wear resistance, and other characteristics are needed. The selection of materials directly affects the performance and lifespan of the blade.
2. Stamping or casting
For some small or thin blades, they can be directly stamped with steel strips or steel plates. For blades made of other materials, it may be necessary to increase the density of the material through casting, which may also result in unnecessary hardness.
3. Precision grinding
After stamping or casting, the blade needs to undergo initial grinding to ensure the accuracy, glossiness, and smoothness of the product. This is a very delicate step in the production process that requires professional equipment and technology.
4. Quenching and insulation
The ground blade needs to be quenched to improve its hardness. Subsequently, in order to increase the wear resistance of the product, a period of insulation treatment is required.
5. Surface treatment
After quenching and insulation treatment, the blade needs to undergo surface treatment, including polishing, grinding, product finishing, glossiness, parallelism, etc. In addition, electrolytic treatment may be required to remove burrs and prevent oxidation.
6. Inspection and Packaging
After completing the above steps, the blade needs to undergo a detailed inspection to ensure that the product is qualified. Finally, package different products accordingly and prepare for shipment.
