Forging is mainly divided into hot forging and cold forging:
Hot forging: It is carried out after the metal material is heated to a certain temperature. It has good plasticity and fluidity and is suitable for forgings with complex shapes. It is often used in large-scale production, such as aerospace, automotive parts, etc.
Cold forging: Pressure is applied to the metal at room temperature, suitable for parts with simple shapes. It emphasizes precision and surface quality, is suitable for small and medium-sized batch production, and is common in mechanical and electronic equipment parts.
The process flow of forging usually includes the following steps:
Raw material preparation: Select metal billets that meet the requirements.
Heating: Heat the metal billet to a temperature suitable for forging.
Forging: Use a forging machine to apply pressure to the heated metal billet to form a forging.
Cooling: Use appropriate cooling methods to ensure the hardness and stable performance of the forging.
Post-processing: Perform necessary post-processing on the forging, such as heat treatment, surface treatment, etc.
