DEMGY

What DEMGY does

DEMGY is a French designer and manufacturer of high-performance plastic and composite components and sub-assemblies, founded in 1947 (originally as Dedienne Multiplasturgy Group) and operating under the current SAS DEMGY corporate structure since 2005. The company's offering is organized around its proprietary Multiplasturgy® concept, a circular one-stop-shop encompassing 15 areas of polymer-processing expertise including injection molding, thermocompression, extrusion, micro injection, additive manufacturing, composite creation, polymer machining, and metallization. DEMGY serves six primary verticals — aerospace, automotive, medical, defense, energy, and sports & leisure — with aerospace accounting for approximately two-thirds of turnover and the company holding Tier 1 supplier status with Airbus and Boeing.

The company operates 14 specialized centers across four countries (France, Germany, Romania, and the United States following the March 2025 acquisition of Tool Gauge, now DEMGY Pacific), supported by three dedicated R&D centers and approximately 900 employees. Its technology portfolio includes registered proprietary assets: Multiplasturgy® (methodology), DataComp® (polymer database), SrPP self-reinforced polypropylene, FlaxComp® bio-composites, P10™ foam, Press&Make thermocompression technology for footwear, and micro injection molding capability. The company maintains the full certification stack required for regulated industries (EN9100, IATF16949, ISO13485, AQAP2120, ISO9001, ISO14001, ISO45001).

DEMGY's business model combines custom project-based B2B manufacturing (hardware sales of finished polymer components and assemblies), direct high-performance polymer sales via the BuyPolymers e-commerce platform, additive manufacturing services via Atelier 3D, and technology licensing. Pricing is quote-based and not publicly disclosed, with multi-year contracts typical for aerospace engagements. Distribution is hybrid: direct enterprise field sales to OEM customers (Airbus, Boeing, automotive OEMs) supplemented by digital commerce channels and proximity manufacturing through regional centers. The company generated approximately €125 million in 2025 revenue and targets €137 million in 2026, with a 2030 ambition of €200 million and 1,500 employees.
