Quality and Production

NOK-FREUDENBERG (CHINA) can provide quality and reliable solutions through three certified, state-of-the-art production sites; Changchun, Taicang and Wuxi. With a long history of exploring the many aspects of production, these production sites are operated with extensive knowledge and experience. Each location has not only been properly certified, but many of our major customers have audited our production processes and awarded certificates that verify our quality.

Such quality is a reflection of the global localization standards applied to our production processes. As the global innovation leader in sealing technologies, we firmly enforce these standards to provide our clients in China with identical high-performance products available in Japan, Europe or America. NOK Corporation and Freudenberg Sealing Technologies conduct extensive internal process tests to verify the replication of materials, machinery, processes and inspection methods as their other production sites.

Only with our passion for details can we provide the high performance solutions that our customers can utilize confidently.
