Modern Manufacturing Technologies

Tenneco uses modern technologies and processes to manufacture our products which meet our customers´ high quality expectations worldwide.

Forming Technology:
State-of-the-art press technology is applied to produce premium components for exhaust systems with complex geometry, i. e. a 400 tons mechanical press in our Edenkoben plant which was commissioned in 2008.
 

 

Joining Fitting Technology:
Joining of high quality raw materials incl. different material combinations is one of Tenneco's core competence. The use of different fitting joining technologies is especially necessary in view of lightweight design in order to assure function and durability of the components. Besides metal arc and resistance welding, laser welding is a standard process established in our facilities. C02 lasers as well as ND:YAG- and diode lasers are in use for various applications. 

Manufacturing of Catalytic Converter and Particulate Filter:
The assembly of a ceramic converter / particulate filter into a metallic housing requires an innovative technology in order to ensure a reliable function in the exhaust gas treatment.
Canning:
The implementation of a fully automatic and flexible manufacturing process for catalysts and Diesel particulate filters allows Tenneco to drastically improve productivity as well as process capability and traceability.

Manifold manufacturing:
The production of fabricated manifolds of various designs , such as the tubular manifold , the shell manifold and the air gap insulated manifold belongs to Tenneco's core competences. Depending on the setting of the task, varying levels of automation up to the fully automated production line are in use. Tenneco's strengths are also the processing of high-quality and exotic materials, such as Ni-based alloys for high temperature applications or titanium for specific lightweight requirements.
Just in Time (JIT)-Production and Just in Sequence (JIS)-Production:
In the JIT-plants, Tenneco pursues the strategy of sequence-in-time production. According to the mounting sequence at the customer's final-assembly line, the exhaust systems are fabricated with a lead time of between 96 and 310 minutes only. A specifically programmed IT-system linked to SAP ensures that the order-to-deliver instruction signals arriving from the customer plant at sequence speed are processed for the robot welding units in real time. Through the synchronization of the production processes with those of the customer, the JIT-plants are able to minimize component handling cost and material lead times compared to manufacturing according to lot sizes - while increasing productivity.
