The Group’s operating business is divided into five segments, as outlined below:

Original Equipment
The Original Equipment segment develops, manufactures, and sells products and assemblies destined for the automotive industry. They include lightweight components, thermal and acoustic shielding systems, cylinder-head and specialty gaskets, battery and fuel cell systems, and complete electric drive units. Supplied to the car and truck market, these products are used in engine, drivetrain, exhaust system, underbody, chassis, and vehicle body applications.

In the Aftermarket segment, ElringKlinger offers an extensive range of high-quality gaskets, gasket sets, and service parts for the professional repair of engines, transmissions, exhaust systems, and auxiliary units in cars and commercial vehicles. They are marketed under the “Elring – Das Original” brand. Business within the Aftermarket segment is transacted through a global network of wholesalers and major group purchasing organizations. Alongside Western and Eastern Europe, the key markets for this area of business in terms of revenue include the Middle East and North Africa. 

Engineered Plastics
The Engineered Plastics segment covers the development, production, and sale of customized products made from various high-performance plastics. Revenue is attributable primarily to sales within the mechanical engineering sector and the medical, chemical, and energy industries as well as the vehicle industry. ElringKlinger is pushing ahead with efforts to grow its business in this segment at an international level, having previously focused on Europe, and is currently stepping up the expansion of its sales and production activities in the United States and China.

Within the Services segment, ElringKlinger provides development and assessment services for engines, transmissions, and the exhaust tract using state-of-the-art testing and measurement facilities. The segment’s customer base includes both vehicle manufacturers and automotive suppliers. This segment also includes logistics services for aftermarket sales and the catering service of a Group subsidiary.

Industrial Parks
The Industrial Parks segment covers the business activities lease and administration, of the industrial parks in Idstein, Germany, and Kecskemét, Hungary. As the Group's strategic focus is on the future-oriented fields of lightweighting and e-mobility, it disposed of its industrial park in Kecskemét, Hungary, in 2019.

The Original Equipment segment is divided into the following divisions: Lightweighting/Elastomer Technology, Shielding Technology, Specialty Gaskets, Cylinder-head Gaskets, E-Mobility, Drivetrain, and Exhaust Gas Purification. The segments Aftermarket, Engineered Plastics, Services, and Industrial Parks correspond to divisions.

Lightweighting/Elastomer Technology
The Lightweighting/Elastomer Technology division has an extensive portfolio that includes lightweight components made of polyamide plastics and fiber-reinforced organo sheets for drivetrain and vehicle body applications. The range of applications is expanding. This is due, in part, to the trend within the automotive industry – specifically also in the commercial vehicle sector – to substitute metal with lightweight components and thus achieve considerable weight savings. At the same time, the refinement of plastics and hybrid technology (i. e., a combination of plastic and metal) has opened up more and more fields of application. As a result, this division offers significant potential for growth. In contrast to the other divisions, the market within this area is much more fragmented.

Shielding Technology
The Shielding Technology division develops and produces thermal, acoustic, and aerodynamic shielding systems. They handle a wide range of tasks relating to temperature and acoustic management in modern motor vehicles, in addition to assisting with aerodynamics along the vehicle underbody. This product area is also of relevance to e-mobility applications, as it covers acoustics and electromagnetic shielding. The product design and associated material composition are dependent on the specific requirements of the field of application within the vehicle. ElringKlinger offers customized solutions for this purpose. ElringKlinger is one of the few suppliers in the world to offer complete shielding packages for both the engine as well as the underbody and the exhaust tract. Based on revenue, the Group ranks as one of the top three suppliers at an international level in this division.

Specialty Gaskets
The product portfolio managed within the Specialty Gaskets division includes a very broad range of gaskets for various engine, turbocharger, transmission, and exhaust tract applications as well as transmission control plates and complex formed parts engineered from sheet metal. Due to the trend toward e-mobility, this division has also seen an expansion within its product portfolio, which now also includes components for batteries and electric motors. ElringKlinger ranks as one of the three leading suppliers worldwide. Competition within this field is extensive due to the relatively high level of product diversity.

Cylinder-head Gaskets
Metallic Cylinder-head Gaskets represent one of the traditional fields of business for ElringKlinger. Drawing on decades of experience in the metal stamping, embossing, and forming processes that are essential to this line of business as well as extensive knowledge in the field of coating technology, the company has retained its long-standing position as market leader in this oligopolistic market. Among its global competitors are, in particular, two major corporations based in the United States.

The E-Mobility division supplies battery and fuel cell components as well as end-to-end battery and fuel cell systems. Building on many years of R&D experience in the field of fuel cell technology, ElringKlinger offers market-ready fuel cell stacks for mobile applications. Having acquired an interest in engineering specialist hofer in fiscal year 2017, ElringKlinger also supplies complete electric drive units (Drivetrain division).

Exhaust Gas Purification
The Exhaust Gas Purification division has seen its business activities shrink significantly since the sale of the Hug subgroup as of March 1, 2018.
