GE Aerospace bets on 'black art' of castings to secure jet engine supply
GE•Strategic logic and antitrust risk
Expansion is not solely driven by bottlenecks.
GE plans to use its LEAN production system to improve efficiency and unlock greater rewards. Analysts say a tone was set by the turnaround and IPO of UK peer Doncasters.
Castings and forgings are also at the centre of a strategic contest between developers of the next generation of engines. China is also pursuing a place in the market, Michaels said.
"They (GE) are expecting a return that allows them to make this work financially, but it also allows them to own a piece of the supply chain that is critical to the future of engine performance," Jerrold Lundquist, managing director of advisory firm The Lundquist Group, said.
Broader competition for advanced metal parts was highlighted last week by Elon Musk who posted that plans by SpaceX to handle separate castings in-house would be a "profound game-changer".
