. Improve the internal structure of metal and improve the mechanical properties of metal; 2. Have high labor productivity; 3. Wide range of applications. The mass of forgings can be as small as less than 1kg and as large as hundreds of tons; it can be produced in single pieces, small batches, or in large batches; 4. The use of precision die forging can make the size and shape of forgings close to finished parts, thus greatly saving metal materials and reducing cutting processing time; 5. It cannot forge forgings with complex shapes.Advantages of forging 1. Improve the internal structure and mechanical properties of forgings. After forging, the structure and performance of the forging blank are improved and enhanced. Forging can eliminate defects such as pores, shrinkage holes and dendrites inside the metal ingot, and due to the plastic deformation and recrystallization of the metal, the coarse grains can be refined to obtain a dense metal structure, thereby improving the mechanical properties of the forging. When designing parts, if the force direction and fiber structure direction of the parts are correctly selected, the impact resistance of the parts can be improved. 2. High material utilization. Metal plastic forming mainly relies on the rearrangement of the relative position of the metal body structure without the need to cut metal. 3. Higher productivity. Forging is generally performed by presses and forging hammers. 4. The precision of the blank or forging is high. Shanxi Yongxinsheng Forging uses advanced technology and equipment to achieve less or no cutting. 5. The metal material used for forging should have good plasticity so that it can produce plastic deformation without breaking under the action of external force.Among the commonly used metal materials, cast iron is a brittle material with poor plasticity and cannot be used for forging. Copper, aluminum and its alloys in steel and non-ferrous metals can be processed by pressure in cold or hot state. 6. It is not suitable for forming forgings with complex shapes. Forging is formed in the solid state. Compared with casting, the flow of metal is restricted and generally requires heating and other process measures to achieve it. It is difficult to manufacture parts or blanks with complex shapes, especially those with complex inner cavities.
