2.Heating: The material is heated to a specific temperature to make it more malleable for forging.
3.Shaping: The heated material is shaped using various methods, such as open-die or closed-die forging.
4.Hammering or Pressing: The material is hammered or pressed into the desired shape using mechanical or hydraulic force.
5.Cooling: The forged part is allowed to cool, typically through air cooling or controlled cooling methods.
6.Trimming: Excess material, such as flash or burrs, is trimmed from the forged part.
7.Finishing: Final machining, surface treatment, or heat treatment is applied to meet the product specifications.
8.Inspection: The part is thoroughly inspected for quality, strength, and dimensional accuracy.
This process ensures the production of strong, precise, and durable forged components for various industrial applications.
