HAL’s Koraput Engine Division Accelerates Indigenous Push: RFI for 20,000-Ton Isothermal Forging Press Signals Aero-Engine Autonomy

In a decisive stride toward self-reliance in aerospace propulsion, Hindustan Aeronautics Limited (HAL)’s Engine Division at Koraput has issued a Request for Information (RFI) inviting Indian vendors to enable the installation of a 20,000-ton isothermal forging press — a critical piece of infrastructure to manufacture large titanium and nickel-alloy components for next-generation aero-engines.
The facility, to be located within the Koraput engine complex, aims to serve major strategic programmes including aircraft engine upgrades, indigenous engine development and foreign collaborations. The 20,000-ton press is one of the heaviest forging units planned in India, and its capability is vital for producing parts like turbine discs and rotor shafts — components that currently rely heavily on imports.
Isothermal forging is a highly specialised manufacturing process where pre‐heated metal is forged at elevated temperatures under precise conditions of strain and temperature control. This ensures superior strength, fine grain structure and high integrity — attributes essential for aerospace engine parts.
The RFI explicitly calls for Indian industrial firms with demonstrated expertise in heavy press design, installation, automation, lifecycle support and stringent aerospace compliance. The HAL unit plans to adopt a phased execution: starting with civil works and foundations, followed by equipment delivery, commissioning, automation, testing and integration.
This move by HAL aligns with India’s broader defence manufacturing strategy to reduce dependence on foreign supplies, strengthen local supply chains and build advanced manufacturing capacity — especially for aero-engines where critical components have been bottlenecked by imports. With the new forging facility, HAL expects to position Koraput as a self-sufficient hub for large alloy forgings, serving both defence and civil aviation sectors.
Execution will hinge on technological tie-ups, vendor selection, funding, regulatory clearances and the ability to industrialise the press at scale. If successful, this project represents a key milestone in India’s drive toward aerospace autonomy and indigenous engine manufacturing.
