Powder forging usually refers to the forming process method of forging into a part in a closed die after heating the powder sintered preform. It is a new process that combines traditional powder metallurgy and precision forging, and combines the advantages of both.

2. Process characteristics The powder forged blank is a sintered body or an extruded blank, or a blank obtained by hot isostatic pressing. Compared with forging with ordinary billets, powder forging has the following advantages:

1. High material utilization

Forging is a closed die forging, there is no flash, no material loss for forgings, and a small margin for subsequent machining. From powder raw materials to finished parts, the total material utilization rate can reach more than 90%. 

2. High molding performance

Metals or alloys that are generally considered unforgeable can be forged. For example, difficult-to-deform high-temperature cast alloys can be forged into products with complex shapes through powder forging, and forgings with complex shapes can be easily obtained.

3. High forging performance

The powder forging preform is heated without oxidation protection, and the precision and roughness after forging can reach the level of precision die forging and precision casting. The optimal preform shape can be used to form complex forgings in the final shape.
