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

Original Equipment
The Original Equipment segment develops, produces and sells parts and assemblies for vehicle engines, transmission units and exhaust systems as well as components for lithium-ion batteries and fuel cells. The client base includes nearly all the world’s vehicle and engine manufacturers. The Swiss subsidiary Hug Engineering AG, Elsau, which forms part of the Original Equipment segment.

In the Aftermarket segment, ElringKlinger supplies a range of spare parts consisting mainly of cylinder-head gaskets and complete gasket sets. These are marketed under the “Elring – Das Original” brand. Supplied in OEM quality, the parts are used primarily for repairs to engines, gearboxes and exhaust systems. The Group’s Aftermarket products are primarily sold in Western and Eastern Europe, the Middle East and North Africa. ElringKlinger is currently expanding its activities in North America and China. Additionally, this segment is in the process of extending its product portfolio within the French and Italian market for spare parts. Business within the Aftermarket segment is transacted primarily through a network of wholesalers and major group purchasing organizations.

Engineered Plastics
The Engineered Plastics segment encompasses the subsidiary ElringKlinger Kunststofftechnik GmbH, Bietigheim-Bissingen/Germany, together with its subsidiaries, including Polytetra GmbH, Mönchengladbach/Germany, a company acquired in 2014. This segment develops, manufactures and sells products made of the high-performance plastic PTFE. Almost half of the Group’s revenue from this segment is generated outside the automotive industry. Within Europe, ElringKlinger Kunststofftechnik has emerged as one of the leading suppliers of products for PTFE applications. China and the United States are served by local sales companies. The ElringKlinger manufacturing plants in these markets operate production lines for PTFE products.

The Services segment is made up of Elring Klinger Motortechnik GmbH, Idstein/Germany, as well as ElringKlinger Logistic Service GmbH, Ergenzingen/Germany, and KOCHWERK Catering GmbH, Dettingen/Erms/Germany. Elring Klinger Motortechnik GmbH provides development services for engines, transmissions and the exhaust tract using cutting-edge testing and measurement facilities. The segment’s customer base includes both vehicle manufacturers and automotive suppliers. As a result, ElringKlinger has established close links with its customers’ development units. ElringKlinger Logistic Service GmbH provides logistics services for the Aftermarket segment and for external customers. KOCHWERK Catering GmbH operates the restaurant at the principal site at Dettingen/Erms/Germany and provides catering services for external customers.

Industrial Parks
The Industrial Parks segment encompasses the Group’s industrial parks in Idstein near Frankfurt/Germany, and in Kecskemét/Hungary. The purpose of the business is to lease and administer buildings.


Segment Proportion of revenue Main customer groups
Original Equipment 83.1% Car, truck and engine manufacturers, automotive suppliers
Aftermarket 9.5% Independent aftermarket business
Engineered Plastics 6.5% Vehicle industry, mechanical engineering, medical technology
Services 0.6% Vehicle manufacturers and suppliers
Industrial Parks 0.3% Unspecified industries


(prior year) in € million 

Segment Proportion of revenue
Original Equipment 1,294.3 (1,255.8)
Aftermarket 147.3 (142.2)
Engineered Plastics 101.7 (96.6)
Services 9.7 (8.3)
Industrial Parks 4.5 (4.3)



The segments are divided into a total of eleven divisions. Seven of these belong to the Original Equipment segment, which at roughly 80% contributes the largest share of total Group revenue. Each of the four remaining segments (Aftermarket, Engineered Plastics, Services and Industrial Parks) also constitutes a separate division.

Cylinder-head gaskets
ElringKlinger is the world’s leading supplier of cylinder-head gaskets. The market is characterized by an oligopoly. ElringKlinger’s two main competitors are US conglomerates that do not actually specialize in gasket solutions. Some of the local markets include smaller, regional competitors.

Specialty gaskets
The Specialty Gaskets division focuses mainly on metal flat gaskets for high-temperature applications relating to engines, turbochargers, transmissions and exhaust systems. The competitive situation is very similar to that of the Cylinder-head Gaskets division. ElringKlinger is a leading player in the field of metal specialty gaskets and is ranked as one of the three largest suppliers worldwide. The Specialty Gaskets division has benefited from ever-higher demands on sealing technology and a growing number of potential applications.

Shielding technology
The Shielding Technology division specializes in combined thermal and acoustic shielding solutions. 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. Of all the Group’s divisions, Shielding Technology accounts for the biggest share of total Group sales. Here, too, ElringKlinger is one of the world’s top three suppliers. The Shielding Technology division also benefits from structural growth, since the number of shielding components required in each vehicle is set to rise over the coming years. The market is more differentiated than in the area of gaskets/seals. ElringKlinger’s main competitor is a US company.

Lightweighting/Elastomer Technology
The Plastic Housing Modules/Elastomer Technology division develops and manufactures lightweight components made of polyamide plastics and fiber-reinforced organo sheets, e.g. cam covers and oil suction pipe modules. The market is experiencing steady growth in the range of potential applications for plastics used in vehicles. Additionally, the truck industry, too, is seeing an ever-growing trend towards the use of lightweight plastic components to replace heavy metal parts. Other key products for this division include high-performance metal-elastomer gaskets for commercial vehicles. The market is more fragmented than in the case of other divisions.

The E-Mobility division focuses on cell contact systems for lithium-ion batteries, which are used in both pure electric and hybrid vehicles. The company’s customer base in this specific area of business also includes two of Germany’s premium car manufacturers. Growth within this division is heavily dependent on demand for electric vehicles. Cell contact systems are available only from a small group of suppliers.

Tooling Technology
Tooling Technology is one of the Group’s core fields of expertise. Accordingly, ElringKlinger has established a dedicated division for these operations. This division encompasses internal tool manufacturing at the site in Dettingen/Erms/Germany as well as specialist plastic injection molding processes performed by Hummel-Formen, Lenningen/Germany. The majority of services provided by this division are attributable to entities within the Group.

New Business Areas
In general, new activities are transferred to dedicated divisions only once they generate their first contribution to revenue at series production level. Until that point, they are pooled under the heading New Business Areas. At present, this category mainly includes ongoing projects relating to fuel cell technology.
