Demgy acquires thermoplastic components supplier E.I.S. Aircraft

Sustainable and intelligent solutions company Demgy Group (Saint-Aubin-sur-Gaillon, France) announces the acquisition of E.I.S. Aircraft GmbH (Euskirchen), a German company specializing in the production of thermoplastic and composite components for the aerospace industry. The purchase will enable Demgy to consolidate its activities in Germany and strengthen its European leadership, promoting its processing of high value-added plastics, high-performance polymers and composites for the aeronautics sector. The company is combined under the Demgy E.I.S. GmbH name.

E.I.S. Aircraft is a long-standing industrial player specializing in cabin interiors, with the production of custom and standard components. It has industrial know-how in composites and plastic injection molding, crucial for Tier 1 suppliers and a large number of OEMs. E.I.S. Aircraft holds numerous patents for products designed and manufactured in its own factories and is unique in that it manufactures its own tools and molds and assembles its own products.  

“Demgy and E.I.S. Aircraft are two of Europe’s historic players in the production of plastic and composite components for the aerospace industry,” Pierre-Jean Leduc, chairman of Demgy Group, emphasizes. “Our two entities are aligned in terms of their values and the strategy of lightening aircraft to promote the decarbonization of the aeronautical sector.”  

With the acquisition, Demgy Group will have two additional production sites in Lemgo and Euskirchen, for a total of 10 plants and a total workforce of 800 people. The former is where the company will design and manufactures injection molded products from thermoplastic components dedicated to the aeronautics sector including equipment for aircraft cabins, armrests, shelves, air ducts, etc. The Euskirchen site specializes in composite materials, from development to assembly and finishing.

Demgy Group anticipates that its sales will exceed €100 million by 2023. Moreover, the company says it will now be able to deploy innovative solutions on a larger scale to lighten structures and offer components created from bioplastics or flax composites (e.g., Flaxcomp). Demgy Group will also enable its current customers and those of E.I.S. Aircraft to benefit from numerous intersite synergies, notably with Demgy Normandie, Demgy Atlantique, Demgy Romania and Demgy Chicago entities.

“This acquisition is a real opportunity for E.I.S. Aicraft to create technological and commercial synergies with Demgy Group,” Dr. Marcus Bernards, director of Demgy E.I.S., says. “Our aim is to make Demgy EIS an even stronger company, and to offer our customers an even more comprehensive range of products and services.”
