Different forging methods have different processes, among which the technological process of hot die forging is the longest, and the general order is:

Forging blank blanking; Forging billet heating; Roll forging for blank preparation; Die forging; Trimming; Punching; Correction; 

Intermediate  inspection for size and surface defects of forgings; Heat treatment of forgings to eliminate forging stress and improve metal cutting performance; 

Cleaning, mainly to remove the surface of the oxide skin; Correction; Inspection, general forging to go through appearance and hardness inspection, important forging also through chemical composition analysis, mechanical properties, residual stress and non-destructive inspection.

Forging is one of the two components of forging (forging and stamping).Through forging, it can eliminate the defects such as the porosity of the cast state generated in the process of smelting, optimize the microstructure and structure, and the mechanical properties of forgings are generally better than castings of the same material due to the preservation of complete metal streamline. 

For the important parts with high load and severe working conditions in related machinery, forging is often used, except for the plate, profile or welding parts with simple shape that can be rolled.
