Wholesale Metal hot forging manufacturers tell you that there are two types of hot forging process, one is the hot forging of powder preform without pre-sintering, which is called powder forging, and the other is the hot forging of powder preform after pre-sintering, called powder sintering forging. Wholesale Metal hot forging manufacturers tell you that most of them use the latter, and sinter in a protective atmosphere to make it have a certain strength, and then heat the perform to the forging temperature.

Wholesale Metal hot forging manufacturers tell you that after heat preservation, it is quickly put into the die cavity for forging, and a forging that meets the design requirements can be forged at one time. Compared with general forging, powder hot forging absorbs the characteristics of the common die forging process, and heats and forges the powder preform to increase the density of the product, so that the performance of the product is close to or even exceeds the level of similar cast products. On the other hand, powder hot forging maintains the characteristics of powder metallurgy technology.

Wholesale Metal hot forging manufacturers tell you that because the powder preform contains about 80% pores, its forging flow stress is much lower than that of ordinary casting materials. Therefore, it can be formed under lower forging energy. At the same time, the shape and size of the preform can be reasonably designed to accurately control its weight, so as to achieve no or less burr forging and improve the utilization rate of materials.

Wholesale Metal hot forging manufacturers tell you that in general, the utilization rate of powder hot forging materials is more than 80%, while that of ordinary forging is only about 50%. Compared with general forged products, powder-forged products have high dimensional accuracy, uniform structure, and no component segregation. Another important feature is the ability to forge metals or alloys that are generally called difficult to forge, such as high-temperature cast alloys that are difficult to deform, and can be forged into various products or products with complex shapes by powder hot forging technology.

Wholesale Metal hot forging manufacturers tell you that powder hot forging technology is developed on the basis of ordinary powder metallurgy and precision die forging technology. Because the powder hot forging process improves the quality of metal products, and at the same time can achieve less or no cutting, simplify the machining process, and save valuable materials and processing hours, which has attracted widespread attention. In many sectors of industry and agriculture, powder hot forging products are widely used. However, its technology is still in the initial stage of development, and it still needs to be gradually perfected and improved in scientific research and production.
