Zehan Hot Forging Service
Zehan has a complete hot forging production line, equipment forging capacity of 20T-3000T, and according to product design requirements, providing high-precision molds, can be used for metal forging of brass, steel, aluminum, stainless steel.
What is hot forging?
The forging process performed on the metal re-crystallization temperature is named hot forging. Hot forging, also known as hot die forging, has a severe flow of deformed metal during forging, and the contact time between the forging and the mold is longer. Therefore, the mold material is required to have high thermal stability, high temperature strength and hardness, impact toughness, thermal fatigue resistance and wear resistance, and is easy to machine. Hot forging dies for lighter workloads can be made from low alloy steel.


The Advantages of Hot Forging
1. Improve the internal structure of the metal and improve the mechanical properties of the metal;
2. Have high labor productivity;
3. A wide range of adaptation. The quality of forgings is as small as less than 1kg and as large as hundreds of tons; it can be produced in one-piece and small-volume production, and can be mass-produced;
4. Using of precision die forging can make the dimension and shape of the forging close to the finished parts, which can greatly save metal materials and reduce cutting work hours.
Average temperatures for hot forging includes:
Aluminum (Al) Alloys - 360° (680°F) to 520°C (968°F)
Copper (Cu) Alloys - 700°C (1 292°F) - 800°C (1 472°F)
Steel(Fe) – 1150°C (2102°F)
