Last year Addmaster won a Queen's Award for Enterprise in the International Trade category, thanks largely to a strong export performance. The company, which prides itself on keeping its manufacturing and R&D operations in the UK, exports to more than 25 countries. Addmaster reports a rise in its latest export figures "of over 125%."
