Exhaust • Flex Bellows

Flexible solutions for automotive and industrial applications

Our products ensure more driving comfort, reduce system vibrations and disruptive noise development while at the same time meeting the highest demands on durability. In addition, our elements successfully contribute to complying with current requirements from environmental and emission regulations. Constant further developments in the automotive and commercial vehicle industries require customized decoupling solutions that meet the respective requirements with regard to environmental specifications, internal combustion engine development and compact assemblies.
These are implemented with appropriately sophisticated technical decoupling solutions. Constant further development of our products in terms of functionality and cost / benefit is our top priority. Numerous patent applications for highly damping decoupling elements as well as the elimination of undesirable component aging phenomena and the introduction of new process capabilities for weight savings and increased durability reflect this development.

Research and Development

TECHNICAL RESEARCH AND DEVELOPMENT CENTER OF THE SJM GROUP IN SOUTH KOREA OFFERS OUR CUSTOMERS OUTSTANDING DEVELOPMENT SUPPORT, INNOVATIVE DESIGN SOLUTIONS AND STATE-OF-THE-ART TESTING AND VALIDATION TECHNOLOGY.

Our company’s expertise in technical development and our customer focus enable us to collaborate closely with all leading automotive and commercial vehicle manufacturers. The team draws on decades of experience, which is compiled in a knowledge database. This database also contains information from vehicle measurements taken on over 30 test tracks belonging to vehicle manufacturers worldwide. This expertise allows for targeted, flexible, and efficient product development.

To enable an efficient development process, we utilize state-of-the-art simulation techniques such as FEA modeling for lifetime prediction. Furthermore, we have our own prototype production line. Local support teams for engineering issues in Europe, North America, India, and South Korea guarantee close and direct contact with our customers’ development departments. Our engineers work seamlessly with the development departments of exhaust system manufacturers and OEMs to develop a comprehensive system solution for each decoupling system, including flexible bellows and thermal management.

Our R&D activities focus on development, validation, and engineering support.

Production

THE CONSTRUCTION AND DEVELOPMENT OF THE TOOLS AND MACHINERY REQUIRED FOR THE COMPONENT PRODUCTION AND MASS PRODUCTION IS ALMOST 100% IN-HOUSE BY SJM.

Using the latest technologies, our production systems are developed exclusively in-house in order to take into account the special manufacturing techniques that are required for production. This allows an efficient design of the production processes, the consideration of product-specific production steps and the compliance with the required quality standards. Thanks to standardized production processes and manufacturing centers, most products can be manufactured at any of our production sites around the world. At SJM, we pride ourselves on offering high quality products. Constant quality control and detailed tests are part of everyday life in production. The production capacities can be adjusted in our decentralized manufacturing plants within a very short time.
