About Composites Busch
Composites Busch SA is a Swiss company based in Porrentruy that has specialized in the development and manufacture of high-performance composites since 1988. The starting point was a newspaper advertisement placed by the Busch Group, actively seeking a 'pioneer in the field of composite materials'. The company offers custom composite solutions along the entire value chain: engineering and co-development with customers, composite manufacturing, additive manufacturing as well as quality management and quality assurance. Materials are primarily carbon and other composites, which are processed into components for the medical technology, watches & luxury, aerospace, space & mobility and industrial sectors. The quality management system is certified to ISO 9001:2015, ISO 13485:2016 and EN 9100:2018. As part of the internationally active Busch Group, Composites Busch manufactures, among other things, vanes for Busch vacuum pumps and was highlighted as a supplier in a Deloitte study on the Swiss watch industry.
