What are the advantages of forging processing?

1. Improve the internal organization of forgings, improve mechanical properties. After forging, the structure and performance of forging blanks have been improved and improved, forging processing can eliminate the porosity, shrinkage and dendrite defects inside the metal ingot, and because of the plastic deformation and recrystallization of the metal, the coarse grain can be refined and the dense metal structure can be obtained, thus improving the mechanical properties of the forging. In the part design, if the force direction and fiber structure direction of the part are correctly selected, the impact resistance of the part can be improved.

2. High utilization rate of materials. Metal plastic forming is mainly based on the relative position of the metal structure rearrangement, without the need to cut the metal.

3. High productivity. Forging processing is generally the use of press and forging hammer for forming processing.

4, high precision of blank or forging.

5, the metal material used in forging should have good plasticity, so that under the action of external force, it can produce plastic deformation without breaking. Among the commonly used metal materials, cast iron is a brittle material with poor plasticity and can not be used for forging. Copper, aluminum and their alloys in steel and non-ferrous metals can be processed under cold or hot pressure.

6, not suitable for forging with more complex shape. Forging process is formed in a solid state, compared with casting, the flow of metal is limited, generally need to take heating and other process measures to achieve. It is difficult to manufacture parts or blanks with complex shapes, especially with complex internal cavities.
