Lightweight Engineering

Lightweight Engineering Competence in Saxony

Saxony’s companies and research institutes provide outstanding expertise for “lightweight construction in efficient material combinations”. In doing so they offer all the requisite competences for the entire value creation chain in lightweight construction -ranging from materials development / characterization, to the engineering / calculation / design of components all the way to innovative processing technologies including quality testing.

Strong R&D clusters

With the Cluster of Excellence “Merge Technologies for Multifunctional Lightweight Structures (MERGE)” at Chemnitz University of Technology and the Dresden University of Technology’s Institute of Lightweight Engineering and Polymer Technology (ILK) and  Europe’s two largest R&D centers for lightweight construction are found in Saxony. In 2016, Dresden‘s, Chemnitz‘s and Freiberg‘s Universities of Technology joined their competences within the „Alliance for lightweight construction in Saxony”.

Lightweight Engineering Companies in Saxony

Action Composites Hightech GmbH, technology and testing center Kesselsdorf

Since 2013, the thyssenkrupp AG has been pooling its activities revolving around high performance lightweight components made of carbon fiber-reinforced plastics (CFRP) in a Tech Center Carbon Composites in Kesselsdorf near Dresden. On August 19, 2019, thyssenkrupp AG announced the sale of thyssenkrupp Carbon Components GmbH to the Austrian Action Composites Hightech GmbH. The main business area of the  Action Composites Hightech GmbH's technology and testing center in Kesselsdorf is the development and production of such vehicle components as, for example, lightweight CFRP wheels which entail weight savings between 30 and 50 percent when compared to conventional aluminum rims.

Located in Frankenberg, the BENSELER Group from Baden-Württemberg supports the lightweight automotive construction industry with its innovative coating procedures. The surface specialists protect both the front axle module of the BMW i8 and the undercarriage of the BMW i3 against corrosion. By applying a special cathodic dip coating (CDC) procedure and thanks to the competences that have been developed in the bonding sector, the ready-to-assemble aluminum components can be attached directly to the carbon passenger compartment in the BMW Plant Leipzig. In addition to cathodic dip coating, the BENSELER Beschichtungen Sachsen GmbH & Co. KG also provides electrostatic powder coating and wet coating. The BENSELER Sachsen GmbH & Co. KG specializes in diverse deburring processes.

The electric car of the future

... will be light, efficient, and affordable. And it will come from Saxony:

  • Scientists at Dresden University of Technology’s Institute of Lightweight Engineering and Polymer Technology (ILK) have developed an ultralight e-car together with the Leichtbau-Zentrum Sachsen GmbH and ThyssenKrupp AG corporations. »InEco®« weighs less than 900 kilograms and is designed to delight primarily short-distance drivers in densely populated urban areas. The car consists of steel-CFRP hybrid components. They unite the best properties of both materials, for example, the low weight of CFRP and the high malleability of steel. This creates components which are not only extremely light, but can also absorb a considerable amount of impact energy in the event of a crash.
  • With the »INNVELO® Three,« the ICM – Institut Chemnitzer Maschinen- und Anlagenbau e. V. has developed a three-wheel, lightweight electric vehicle together with its partners from Saxony which was specifically designed for individual trips in densely populated areas and for its use in the small business sector. The vehicle combines the advantages of an electric bicycle (light, inexpensive) with those of an electric car (convenience, cruising range, speed).


The Mittweida-based COTESA GmbH specializes in the production of fiber-reinforced composite components. Since its founding in 2002, the COTESA GmbH has evolved into an important series supplier for many big aerospace companies. Its customers include Airbus, Airbus Helicopters, ESW, and the Diehl Group. COTESA manufactures, for example, extremely lightweight, curved sandwich structures, CFRP profiles, and bulletproof lightweight components. The company possesses state-of-the-art production facilities with a number of autoclaves as well as CNC processing technology and can build components with sizes of up to 8 x 2 meters.

The EAST-4D Carbon Technology GmbH in Dresden is dedicated to the topic lightweight construction with ultramodern procedures. The company develops ideas and project proposals in line with specific customer requirements. Design and approvals are implemented individually in further process steps. For the mass production of ultralight composite structures, the company has developed the filament winding forming and the filament winding injection procedure. These procedures permit the production of both rotating components with complex geometry and nacelles which are exposed to maximum stress. With this patented technology, EAST-4D produces, for example, the jet engine inlet cone for the Airbus A350 900 XWB. 


The Leichtbau-Systemtechnologien KORROPOL GmbH (LSK) is a specialist for innovative lightweight applications in machine and plant construction as well as the aerospace and energy technology sectors. With more than 50 years of experience in fiber composites, KORROPOL is one of the most traditional GFRP and CFRP processing companies in Germany. The production in Dresden focuses primarily on structural components as well as the requisite GFRP forming dies and tools. Through such customers as, for example, BMW, Voith, VEM, Airbus, Volkswagen, and many more, KORROPOL products are found in more than 20 countries around the entire globe. The company’s spectrum encompasses, for example, support structures and robotic hands, machine housings, equipment items for wastewater treatment plants and sewage systems, trim and cladding components for rail technology as well as wall and ceiling panels, design objects, and façade claddings.


The Chemnitz-based FIBER-TECH Products GmbH manufactures customer-specific structural components from fiber composite materials (GFRP, CFRP, textile-reinforced ceramics) – for example, rotor blades for wind turbines or elements for improved acoustics in the Deutsche Staatsoper Berlin opera house.
