Located in North Rhine-Westphalia, near Bielefeld and Hanover, DEMGY Lemgo is one of DEMGY E.I.S. GmbH's two German sites, specializing in high-performance polymer injection molding for civil and military aircraft cabins. The site covers design, tooling, series production and assembly of engineering thermoplastic parts for Airbus, Boeing and Embraer programs.

Over 60 years of aerospace thermoplastic injection know-how, under EN 9100:2018.

High-performance thermoplastic injection molding

Injection molding is used as a direct alternative to metal, laminated composites and hybrid structures, with equivalent mechanical performance at significantly reduced weight — supporting airline DOC (Direct Operating Cost) targets per CS-25 and FAR 25.

Engineering polymers

PEEK, PEI (Ultem™), PSU (polysulfone), PPS, PPA, PPO, PC/ABS, ABS with FST (Fire, Smoke, Toxicity) formulations, aligned with Airbus ABD0031 and Boeing BMS. Direct grade access via BuyPolymers DEMGY.

In-house tooling & industrial capabilities
