China hot forging machine maker
In modern manufacturing industry, forging technology is one of the key processes to produce high quality metal parts. Among the many forging methods, hot die forging stands out with its unique technical advantages and performs well in improving product strength, precision and surface quality.
Hot die forging can significantly improve the strength of the product. In the process of hot die forging, the metal material is heated to a higher temperature, which enhances its atomic activity and greatly improves its plasticity. This allows the material to flow and fill more fully under the action of the mold, eliminating the internal pores and porosity and other defects, thus forming a dense microstructure. For example, in the manufacture of automobile engine connecting rod, the use of hot die forging process can greatly improve the strength of the connecting rod, can withstand the complex load of the engine, and reduce the risk of fracture and failure.
In terms of accuracy, hot die forging also has obvious advantages. Due to forging at high temperatures, the deformation resistance of the metal is reduced, and the mold is able to exert more precise pressure and shape control over the material. Moreover, the hot die forging die is usually manufactured by high-precision processing technology, which can ensure that the dimensional accuracy of the forged product reaches a high level. Taking the manufacturing of precision parts in the watch movement as an example, hot die forging can accurately shape complex shapes and fine structures to meet the requirements of high-precision operation of the watch.
Hot die forging is also great at improving the surface quality of products. In the forging process, the metal material at high temperature is fully in contact with the surface of the mold, forming a uniform pressure distribution, thereby reducing surface wrinkles and scratches and other defects. At the same time, the product after hot die forging usually does not require a lot of subsequent processing, such as grinding and polishing, to obtain a good surface finish. For example, in the production of key components in the aerospace sector, hot die forging provides products that meet stringent surface quality standards, ensuring reliable operation in environments such as high speed, high pressure and high temperatures.
