Xinjinghe leverages metal LPBF to manufacture aero-engine and gas turbine components

Xinjinghe, a Chinese metal additive manufacturing specialist, has detailed its production of aero-engine and gas turbine components using its in-house LiM-X series laser powder bed fusion (LPBF) systems. The company reports manufacturing parts including guide vanes, turbine nozzles, closed impellers, thrust chambers, oxygen pump housings, and combustor liners from aluminum alloys (AlSi10Mg), nickel superalloys (GH3625), and pure copper (T2). Xinjinghe's LiM-X platform covers build volumes from 150 mm to 2000 mm, supporting both single-part prototyping and batch production. The company also offers automated production line solutions for serial manufacturing.

This announcement reinforces the Chinese localization arc in metal AM, where domestic suppliers are integrating machine hardware, materials, and process know-how to serve the aerospace and energy sectors. Xinjinghe's focus on aero-engine and gas turbine components places it in direct competition with established Western and Chinese metal AM service providers targeting the same qualification-heavy verticals. The company's ability to demonstrate production of hot-section parts from multiple material classes - including copper for thrust chambers and nickel superalloys for turbine nozzles - suggests a broadening of process capability beyond titanium and aluminum. This matters because aerospace qualification remains the highest-barrier application for metal AM, and Chinese suppliers are increasingly building the reference base needed to compete for domestic and export programs.

From an industry perspective, Xinjinghe's strategy mirrors the pattern seen across Chinese AM firms: vertical integration of equipment, materials, and service to reduce dependency on foreign supply chains. The practical question is whether the company can translate these demonstration parts into repeatable, qualified production at scale - particularly for safety-critical rotating components. For buyers evaluating Chinese metal AM sources, the key differentiator will be not just machine specs or material coverage, but documented process qualification and delivery track records with tier-1 engine OEMs.
