Sigma has operated in global aerospace markets for over 10 years. With manufacturing facilities across the UK and China, our customers have benefited from a wholly-owned, dedicated capability in China since 2006.

Each of our businesses, in either the UK or China, offers specialist expertise in engineering, operations, purchasing and quality, ensuring we provide a broad range of services to customers across the aerospace sector.

Customers can deal with whichever location is most convenient to them, while our multi-lingual customer-facing teams manage all ‘back-office’ activity to ensure we get your aircraft parts to you on time and in full.
