In the field of metal processing, hot die forging, as a kind of precision forging technology, plays an important role in industrial production by virtue of its unique technical characteristics. Hot die forging, as the name suggests, is the placing of metal blanks heated to high temperatures in a mold, which is plastically deformed into the desired shape and size by the action of pressure. In this process, hot die forging has shown remarkable characteristics such as high precision, good surface quality, high material utilization rate and fast production efficiency, which make hot die forging stand out among many forging technologies.

High precision

One of the core advantages of hot die forging is its ability to achieve high precision machining. In the process of hot die forging, the metal blank has good plasticity at high temperatures and can be tightly fitted to the mold cavity, thus ensuring the accuracy of the size and shape of the forging. Compared with free forging, hot die forging does not rely on manual operation, reduces the human error, and greatly improves the dimensional accuracy of the forging. At the same time, the high guiding accuracy of the hot die forging press and the design of the combined die with the guide post further ensure the dimensional stability of the forging. This high precision makes hot die forging widely used in industries such as aerospace and automobile manufacturing, which require very high precision parts.

Good surface quality

Another notable feature of hot die forging is the surface quality of its forgings. Under the joint action of high temperature and high pressure, the surface defects such as cracks and inclusions of the metal blank are effectively eliminated, and the metal flow is more uniform, reducing the surface roughness and roughness. In contrast, although cold forging can also obtain better surface quality, but because of the poor plasticity of the metal in the cold state, it is easy to produce cracks and uneven deformation. Free forging is more difficult to ensure the surface quality of the forgings, often require subsequent processing to meet the requirements. Therefore, hot die forging has obvious advantages in the production of parts that require high-quality surfaces.

High material utilization rate

Hot die forging also performs well in improving material utilization. Due to the good flow of metal at high temperatures, the mold cavity can be filled more fully, reducing the generation of flash and residual material. In addition, through reasonable mold design and process optimization, the utilization rate of materials can be further improved. In contrast, free forging needs to reserve a large processing margin, and the material utilization rate is relatively low. Although cold forging can also obtain a higher material utilization rate, it is limited by the cold plasticity of the metal, and its application range is relatively limited. Therefore, in the pursuit of efficient use of materials today, hot die forging is undoubtedly a more ideal choice.

Fast production efficiency

Hot die forging is also known for its high productivity. In the automated production line, the hot die forging press can continuously carry out forging operations, which greatly improves the production efficiency. At the same time, due to the accuracy and stability of the mold, the rejection rate and rework rate are reduced, and the overall production efficiency is further improved. In contrast, free forging and cold forging are difficult to compete with hot die forging in terms of productivity. Free forging depends on manual operation and experience judgment, the production efficiency is low and it is difficult to ensure quality stability; Although cold forging can also achieve automated production, it is limited by the cold plasticity of the metal and mold wear and other problems, and its production efficiency is relatively low.

To sum up, hot die forging with its high precision, good surface quality, high material utilization rate, fast production efficiency and other characteristics, in the field of metal processing has shown a strong competitiveness and broad application prospects. With the continuous progress of technology and process optimization, hot die forging will play an important role in more fields and promote the sustainable development and progress of related industries.
