Isothermal Forging Technology:
Isothermal forging is a closed-die process in which the dies and the workpieces are heated to the same temperature, so that forming can take place without loss of temperature in the workpiece.
- It’s a preferred process for forming engineered parts, including jet-engine and other aerospace components in high-density lightweight alloys.
- In this process, the workpiece is formed to shape at a slow rate and at a temperature almost equal to that of the heated die.
- The long forging time, alongside forces exerted by the die, help to form an almost ‘ready to use’ component needing minimal supplementary machining.
- This is a crucial technology for establishing self-reliance in aeroengine technology.
- With this development, India has joined the league of limited global engine developers to have the manufacturing capabilities of such critical aero engine components.
