Precision engineering group Doncasters is looking to grow in key sectors including aerospace with a $919.3 million capital boost from its New York Stock Exchange initial public offering on June 25. The UK-based group, founded in 1778, produces an array of nickel- and cobalt-based superalloy components such as airfoil blades and vanes, engine structural castings, and hot-side turbocharger wheels.
Doncasters’ aerospace customer base includes Safran Aircraft Engines, for which it supplies structural and hot-section airflow castings for the CFM International Leap-1A and 1B turbofans. It also produces blades and vanes for several other propulsion systems under long-term supply agreements.
In recent months, the company has started building a 32,000-sq-ft production facility at its site in Bochum, Germany, as part of plans to strengthen its aerospace supply chain. This work is part of a $52 million investment in the facility announced in December 2025, which also includes new furnaces to be installed over the next 12 months. The group has 14 production locations across Europe, Asia, and North America.
For components with complex internal features, Doncasters uses the customer’s design to produce the precision ceramic core that will be used for superalloy casting. From this, it makes a wax replica mold and coats the structure with strengthening materials before firing the ceramic shell to remove the wax. Once the structure has solidified, the ceramic mold is removed and the surfaces trimmed to remove excess metal before further strengthening processes.
