Ducommun Inc was founded in California in 1849 and was reincorporated in Delaware in 1970. The Company through its subsidiaries provides engineering and manufacturing services for high-performance products and high-cost-of failure applications used primarily in the aerospace, defense, industrial, natural resources, medical and other industries. The Company has two operating segments; Ducommun LaBarge Technologies and Ducommun Aerostructures. Ducommun LaBarge Technologies segments designs, engineers and manufactures products used in technology-driven markets including aerospace, defense, natural resources, industrial and medical and other end-use markets. Its products range from prototype development to complex assemblies. Its products offerings includes electronics manufacturing for diverse, high-reliability applications; complex cable assemblies and interconnect systems, printed circuit board assemblies, and higher-level electronic, electromechanical and mechanical assemblies. Components and assemblies are provided principally for domestic and foreign commercial and military fixed-wing aircraft, military and commercial helicopters and space programs. It provide selected non-aerospace high-reliability applications for the industrial automation, natural resources (mine automation and drilling), and medical device end-use markets. We build custom, high-performance electronics and electromechanical systems. Ducommun LaBarge Technologies through Ducommun Miltec missile and aerospace system design, development, integration, and test. Its expertise includes engineering capabilities in systems engineering, aerodynamics, propulsion, guidance-navigation-and control ("GNC"), lethality/warheads, simulations, avionics, structures, software, inertial measurement units, seeker/sensors, and signal/data processing. Ducommun Aerostructures products are used on commercial aircraft, military fixed-wing aircraft and military and commercial rotary-wing aircraft. DAS has three major product offerings to support a global customer base: commercial aircraft, military fixed-wing aircraft, and military and commercial helicopters. Our applications include structural components, structural assemblies and bonded (metal and composite) components. In the structural components products, DAS designs, engineers, and manufactures large complex contoured aluminum, titanium and Inconel aerostructure components for the aerospace industry. Structural assemblies' products include winglets and fuselage structural panels for aircraft. Metal and composite bonded structures and assemblies products include aircraft wing spoilers, large fuselage skins, helicopter rotor blades and components, flight control surfaces and engine components. To support these products, DAS maintains advanced machine milling, stretch-forming, hot-forming, metal bonding, composite layup, and chemical milling capabilities and has an extensive engineering capability to support both design and manufacturing. The raw materials used in the manufacture of the products include aluminum, titanium, steel and carbon fibers, as well as a wide variety of electronic interconnect and circuit card assemblies and components. Its products offerings support customers such as commercial aircraft, military fixed-wing aircraft and military and commercial helicopters. The Company had significant sales of Boeing and Raytheon. The Company competes with domestic and international companies in several markets. It competes primarily with Tier 2 and Tier 3 suppliers. The Company's business, operations and facilities are subject to numerous stringent federal, state and local environmental laws and regulations issued by government agencies.
