Precision forging refers to the forming technology that only requires a small amount of processing or no processing after the parts are forged to meet the requirements of the parts. It is an important part of advanced manufacturing technology. Precision forged parts manufacturing processes are widely used in many industries such as automobiles, mining, energy, construction, aviation, aerospace, weapons, etc.
High precision: The most important feature of precision forged parts is that they have high dimensional accuracy. This high precision is achieved through precise molds, advanced process control and suitable equipment during the forging process. For example, in the manufacturing of precision forged parts in aerospace, such as the integral blade of the engine and the large blades of the aircraft, the dimensional control requirements are extremely strict, and the dimensional accuracy can reach or even exceed the traditional processing methods, thereby reducing the subsequent adaptability problems in the assembly and use process.
High-quality surface quality: The surface of the parts after precision forging is relatively smooth and flat, and the precision can control the surface roughness at a good level. Because some problems such as surface roughness and uneven texture caused by the processing method are avoided in the forging process, in some cases, the surface of the forged parts almost does not require additional surface treatment to meet the use requirements. For example, in the field of medical devices, the high-quality surface quality of precision forged parts can reduce the risk of bacterial adhesion.
Applicable to a variety of materials: It is applicable to metal materials, such as high-temperature alloys, titanium alloys and high-strength alloy steels, which are commonly used in aerospace and energy fields, as well as some commonly used steel materials, non-ferrous metals, etc. Different materials can play their characteristics in precision forging and be formed into qualified parts through precision forging processes. For example, the precision forging application of aluminum alloys in the automotive field can reduce the weight of the car and contribute to the lightweight design of the car.
High material utilization rate: Precision forging can control the flow and distribution of materials more accurately, reducing the waste of materials in traditional forging or machining processes. For example, some large structural parts can use raw materials more reasonably through precision forging technology, realize efficient use of materials, and thus reduce costs.
Improve the mechanical properties of materials: In the process of precision forging, after the material undergoes plastic deformation, the internal organizational structure is improved, and the internal crystal phase is rearranged and refined, so that the mechanical properties of the parts such as strength, toughness, and hardness are greatly improved. For example, the mechanical properties of some turbine parts in the energy field are significantly improved after precision forging compared with traditional manufacturing methods, enhancing the operating stability and reliability of the entire equipment.
